In recent years, countries in the Global South have increasingly engaged in marine ecological governance in response to mounting environmental pressure and the increasing prominence of sustainable development agendas. Against this backdrop, this study examines the evolution of marine ecological governance thinking and the logic of international cooperation in Brunei, a maritime member of the Association of Southeast Asian Nations (ASEAN). This study provides a systematic and dynamic analysis of how a small Global South state has transformed its governance approach, thereby integrating it into regional and global governance frameworks. This study adopted a qualitative research design based on policy analysis, literature review, and case study methods. It constructed an analytical framework centered on governance pathways and examined marine ecological governance in Brunei across institutional, organizational, and cooperative dimensions. This study identified the structural features and operational logic of Brunei’s governance model by synthesizing official documents, international cooperation initiatives, and existing academic research. The findings indicate that Brunei has undergone a profound transformation from a traditional experience-based governance approach to a modern model characterized by institutionalization and scientific management. Since the beginning of the 21st century, Brunei has gradually established a comprehensive governance system supported by five key pathways: 1) legal regulation has been strengthened by improving legislation on marine pollution prevention and environmental protection, and fisheries resource management, thereby forming an institutional framework that covers critical aspects of marine ecological protection; 2) organizational management has been advanced through cross-departmental coordination and a whole-of-government approach, enabling integrated governance of marine affairs; 3) international cooperation has been expanded by actively participating in bilateral and multilateral mechanisms, thus constructing a multilevel and multidimensional network for marine ecological governance; 4) scientific and technological support has been enhanced by promoting research incentives and industry-academia-research collaboration, thereby strengthening the knowledge base and technical capacity of governance; and 5) public participation has been fostered through education and multi-actor engagement, thereby improving societal awareness of, and involvement in, marine ecological protection. Through interactions between these pathways, Brunei has developed a relatively systematic and coordinated governance model. This model has enabled the country to actively engage in regional and global marine ecological governance agendas, promote environmental restoration, and generate positive socioeconomic outcomes. The results further suggest that Brunei’s governance practice reflects a distinctive "small-state pathway" within the Global South, characterized by institutional consolidation, external cooperation, and capacity-building strategies. However, the study also found that Brunei continues to face several constraints, including limited natural and financial resources, increasingly complex governance issues, and the persistent tension between economic development and environmental protection. These challenges may affect the sustainability and scalability of the governance model. This study contributes to existing literature in several ways. It enriches the Global South perspective by highlighting the role of small states in global marine ecological governance. These findings offer empirical support for understanding how governance capacity can be enhanced through multipathway coordination. Moreover, the study provides policy implications for advancing regional cooperation, particularly in promoting the construction of a China-ASEAN maritime community with a shared future and a China-ASEAN blue partnership. By doing so, it can help to strengthen the voices and participation of Global South countries in global marine ecological governance.

Cross-regional venture capital investments are crucial drivers for reshaping urban and regional economies, and their structural characteristics and operational mechanisms are popular topics in economic and urban geography. Based on intercity venture capital flows in the Yangtze River Economic Belt from 2006 to 2022, directed and weighted networks were constructed at six time points, and the network structural characteristics were analyzed from the perspectives of micro-node hierarchy, meso-cluster classification, and macro-topological attributes. Subsequently, the underlying operational mechanisms of intercity venture capital flows were further explored through the lenses of endogenous structural, urban attribute, and external contextual effects using exponential random graph models. The results showed that (1) Shanghai has consistently remained the core of venture capital networks in the Yangtze River Economic Belt, followed by Hangzhou, Nanjing, Wuhan, Chengdu, and Chongqing. Investment clusters are highly aligned with provincial or regional administrative boundaries, forming a strong cluster in the Yangtze River Delta, a dual-core cluster in Chengdu and Chongqing, a multicenter cluster in the middle reaches of the Yangtze River, and emerging clusters in Yunnan and Guizhou. (2) The core-periphery differentiation of intercity venture capital networks in the Yangtze River Economic Belt is prominent. The overall investment scale and intercity investment intensity of the networks increased, reciprocity and small-world characteristics were continuously strengthened, and network structures were gradually optimized. (3) The endogenous operational mechanisms of intercity venture capital flows in the Yangtze River Economic Belt evolved from reciprocal and preferential attachment mechanisms in the early stage to a later triadic closure mechanism driven by multiparty games. Regarding the exogenous operational mechanisms, the globalization, marketization and urbanization of cities promoted intercity venture capital flows, however, the roles of globalization and urbanization were decreasing whereas the role of marketization was increasing; the driving force of geographical and organizational proximity between cities to intercity venture capital flows was also decreasing. Based on these empirical findings, this study proposes policy recommendations for optimizing financial resource allocation and promoting coordinated regional development through network agglomeration and diffusion, urban functional division and interaction, and intercity barrier breaking and integration. Departing from existing research, this study systematically aligns network structural analysis with operational mechanisms across the micro-, meso-, and macro-levels, constructing an integrated multiscale analytical framework and a simulation methodology for complex networks. The applicability of this framework is validated through empirical investigation of intercity venture capital networks in the Yangtze River Economic Belt with the aim of deepening our understanding of intercity venture capital investment mechanisms while providing insights for research on other urban networks.

With the accelerated transition of the global energy structure and expansion of the renewable energy sector, critical materials such as rare earth elements are becoming increasingly important in the wind power industry chain. However, the current complex geopolitical environment, constrains the free flow of the global wind power supply chain. Therefore, the trade network structure and evolutionary characteristics of critical products must be analyzed from a segmented industry chain perspective. Simultaneously, the Belt and Road Initiative (BRI) provides a multinational cooperation framework to systematically assess its role in promoting the integration of participating countries into the wind power industry chain trade network, enhancing their trade network positions, and alleviating resource and technology constraints. This study constructed a segmented global trade network for the wind power industry chain and quantitatively examined how BRI affects the trade network positions of participating countries, along with the underlying mechanisms. The study draws on trade data from 52 major countries and regions for the 2009-2022 period. Rare earth ores, rare earth permanent magnets, and direct-drive wind turbines were selected to represent the upstream, midstream, and downstream segments of the industry chain, respectively. A directed and weighted trade network was constructed to capture the structural characteristics and evolutionary trends of the network. A multi-period difference-in-differences model was employed to evaluate the impact of the BRI on the trade network positions of countries along the initiative’s route, and mechanisms such as policy coordination, infrastructure connectivity, and trade facilitation were incorporated to assess the channels through which the initiative affects trade network embedding. First, the results indicate that the global wind power industry chain trade network has become increasingly complex, with a growing scale, enhanced connectivity, and significant small-world properties across all segments, reflecting the networked nature of the global supply chain. Among the segments, the midstream permanent magnet network exhibited the highest connectivity and clustering, the upstream rare earth network was sparse, and the downstream complete turbine network was constrained by market access limitations and standardization levels. Second, Germany, the United States, and China are core countries across different segments, whereas the networks of major participating countries are becoming increasingly diversified, with resource-rich European countries such as Denmark and Belgium gaining greater importance over time. China’s position exhibits a composite pattern of "strong downstream, stable midstream, weak upstream," and through systematic cooperation under the BRI, its network position has improved. Despite certain bottlenecks in key technological control, China has become a key component in the global wind power industry chain, significantly influencing the production and application of wind power equipment. Finally, BRI significantly enhanced the trade network positions of participating countries in the wind power industry chain. The initiative’s effects exhibited pronounced heterogeneity across industry chain segments, levels of national development, and spatial corridors, with particularly strong effects observed for resource- and technology-intensive segments, developed countries, and countries along the Silk Road. The mechanism analysis indicates that policy coordination enhances network embedding through intergovernmental cooperation and foreign aid, whereas infrastructure and trade facilitation improve shipping connectivity and reduce tariffs, thereby indirectly enhancing the trade position of the countries. The contributions of this study are twofold. First, it constructs a global wind power trade network from a segmented industry chain perspective, revealing heterogeneous characteristics across segments. Second, it systematically evaluates the effects of the BRI on the policy, infrastructure, and trade dimensions, providing theoretical and practical guidance for formulating international renewable energy cooperation policies and optimizing the industry chain layout for participating countries.

Amidst the global transition toward renewable energy, China has emerged as the world leader in solar photovoltaic (PV) capacity and generation. However, the climatic risks and operational stability of this extensively deployed PV infrastructure under future climate change remain insufficiently assessed. Previous studies have primarily focused on the theoretical PV power-generation potential (P_solarPV) across terrestrial areas, overlooking the specific climatic risks of existing operational PV facilities. This study addresses this critical gap through a comprehensive, multi-dimensional risk assessment for China's deployed PV systems. We developed a high-resolution hourly P_solarPV model driven by a multi-model ensemble from the NASA Earth Exchange Global Daily Downscaled Projections (NEX-GDDP-CMIP6) under three greenhouse gas (GHG) emission scenarios from 2015 to 2060. Focusing on China’s existing deployed PV infrastructure and seven representative regions, we quantified future changes in annual P_solarPV and their driving factors, the frequency of extreme PV power events (energy "surplus" and energy “deficit” days), and intra-annual variability (short-term fluctuations and seasonal variations). Our results reveal that future trends in P_solarPV across China’s PV deployments are shaped by the opposing effects of increasing solar radiation (positive effect) and rising surface temperatures (negative effect). Under the low-emission scenario (SSP1-2.6), enhanced solar radiation dominates, leading to a nationwide increase in annual P_solarPV of 3.4%±0.4% (multi-model mean ± standard error). In contrast, under the high-emission scenario (SSP5-8.5), thermal-induced efficiency losses offset these gains, resulting in a slight increase of 0.6%±0.4% in P_solarPV and a rise in the frequency of poor-power days by 0.1 d per decade. Moreover, climate-induced impacts exhibited pronounced spatial heterogeneity. With increasing GHG emissions, deployed PV systems in northwestern, northern, and eastern China are projected to be the most climate-sensitive, experiencing greater changes in power-generation potential and more frequent extreme power-generation events. Northwest China, where PV deployments are concentrated, is projected to experience a decline of -0.5%±0.2% in P_solarPV and an increase of 1.0 d per decade in extreme poor-power days under the high-emission scenario. Conversely, the deployed PV systems in South and Southwest China exhibited stronger climate resilience. Furthermore, higher GHG-emission scenarios are expected to intensify seasonal and short-term P_solarPV fluctuations, especially in northern regions (e.g., Northeast, North, and Northwest China), posing greater challenges to grid stability and power dispatch management. In conclusion, this study provides the first location-specific, forward-looking climate risk assessment of China's existing PV infrastructure. These findings highlight that stringent GHG mitigation is critical for safeguarding solar energy assets and ensuring the long-term sustainability of PV power generation. They also emphasize the need for spatially differentiated climate adaptation strategies, including optimizing future deployment in climate-resilient regions, strengthening grid capacity with advanced energy storage, and enacting policies that enhance the climate resilience of China’s solar power system.

In the context of ecological civilization construction and high-quality development, exploring the mechanisms of local environmental governance transformation under globalization is of substantial academic significance for understanding regional sustainable development. Existing studies on environmental governance in the Pearl River Delta (PRD) have mainly examined the driving forces from a single perspective, such as economic development, industrial structure, and globalization. However, relatively limited attention has been paid to identifying the hierarchical roles and evolutionary dynamics of multiple factors from a multi-scalar interaction perspective, particularly the intermediary roles of institutional spillovers from Hong Kong and Macao in regional governance. To address this gap, this study develops an analytical framework of "globalization input-local response-environmental governance" from the perspective of the geography of sustainability transitions. Using the GeoDetector method, this study systematically examined the spatiotemporal evolution of environmental regulation intensity and its driving mechanisms across nine cities in the PRD from 1990 to 2018. The main findings are as follows. First, environmental regulation intensity in the PRD has increased continuously over time, exhibiting distinct stage-based transitions and forming a spatial gradient centered on highly open cities such as Shenzhen and Guangzhou. Second, the driving forces of local environmental governance evolved from an endogenous, development-driven stage dominated by economic growth and urbanization to a multi-scalar governance mode characterized by interactions between globalization inputs and local institutional responses. Lastly, institutional opening channels play a critical bridging role in governance transition. In particular, the number of first-class ports demonstrates the strongest explanatory power, indicating that global environmental rules and governance concepts are primarily embedded in local governance systems through institutional channels of opening. Under the influence of Hong Kong’s and Macao’s institutional spillovers, these processes further promote local institutional innovation and improve governance capacity. This study suggests that, in highly open regions, environmental governance transformation is driven jointly by global rule diffusion, local institutional absorption, and cross-jurisdictional institutional interactions. By revealing the evolutionary mechanisms of environmental governance from a multi-scalar interaction perspective, this study extends the explanatory power of the geography of sustainability transitions in the context of cross-border institutional interactions and regional institutional diversity. It provides new theoretical insights and empirical evidence for understanding environmental governance transformation in open regions.

This study proposed a theoretical framework of "spatial justice perception-psychological transformation-behavior formation." Using multisource data, including semi-structured interviews, participatory observations, and secondary materials, the research applied a constructing grounded theory approach involving a four-level coding analysis: initial coding, focused coding, axial coding, and theoretical coding. By deconstructing individuals’ perceptions of spatial injustice, this study reconstructed the dimensions of spatial justice and examined the differences in perceptions and behavioral mechanisms between tourists and local residents. The key findings are as follows: (1) Both tourists and residents derive their spatial justice perceptions from issues of spatial injustice, which are reconstructed in four core dimensions: distributive justice, procedural justice, recognition justice, and restorative justice. For tourists, the psychological transformation mechanism operates as follows: perceptions of distributive, recognition, and restorative injustice trigger disappointment in service value, alienation in the cultural experience, and a sense of lack of ecological education, leading to imbalanced spatial value perception. Perceptions of distributive and recognition injustice shape cognitive biases such as deviation from group preferences and a lack of cultural respect, resulting in conflicts with spatial discipline. Perceptions of distributive and restorative injustice weaken behavioral confidence and decision-making autonomy, causing diminished spatial agency. For residents, perceptions of distributive, recognition, and restorative injustice induce survival anxiety, cultural anxiety, increased economic burden, reinforced doubts about fairness, and a heightened sense of deprivation, leading to perceived spatial survival pressure. Perceptions of procedural injustice foster intergroup opposition, intensify value conflicts, and erode group trust, resulting in a torn spatial identity. Perceptions of procedural and restorative injustice jointly reduce decision autonomy and undermine developmental confidence, leading to reduced spatial empowerment. (2) Structural differences exist between tourists and residents in spatial justice perception and behavior, rooted in the profound tension between two spatial attributes—"paradise" vs "homeland"—and their respective subject positions. Tourists who occupy transient, consumption-oriented positions prioritize experiential rights. They often expressed dissatisfaction through negative word-of-mouth, passive participation, on-site compensation, or rule-breaking adventures. Their negative behaviors generate short-term public opinion and operational pressure, whereas their long-term effects can undermine destination attractiveness. Residents situated in fixed livelihood-dependent positions emphasize their rights to survival, development, and culture. They tend to adopt resistance measures, such as boycotts, collective action, external appeals, covert resistance, and strategic gaming. Their negative actions easily provoke governance conflicts and social risks, potentially undermining the legitimacy of governance in the long term. This study contributes theoretically by deconstructing differences in spatial justice perceptions between tourists and residents of Potatso National Park, and deepens the connotation of spatial justice theory in ecological conservation contexts, complementing existing research focused on urban development. Second, it innovatively proposes "restorative justice" as a key dimension in ecological conservation, defining it as "dismantling structural roots of injustice through systematic intervention to halt the reproduction of spatial conflicts and achieve sustainable reconciliation of eco-social relations." Finally, moving beyond macro-structural perspectives, this study constructed a micro-level analytical framework, offering new theoretical tools to analyze the psychological formation of spatial justice and advance national park governance. Practically, this study systematically identifies real-world issues in Potatso National Park’s conservation and management, analyzes the underlying mechanisms, and proposes targeted, multi-dimensional governance strategies tailored to different stakeholders. This study provides concrete pathways for enhancing park governance effectiveness.

The "tidal phenomenon" of tourist flows in rural destinations—characterized by peak-season overcrowding and off-season stagnation—poses a critical barrier to sustainable development. Conventional hard strategies, such as capacity expansion and price regulation, are often inefficient and may undermine local authenticity. The soundscape, as a largely overlooked form of sensory capital, offers potential to flexibly guide tourists’ spatio-temporal behavior; however, its underlying mechanisms remain unclear. This study integrates sensory capital, cultural acoustics, and spatio-temporal fix theories to construct a "value-meaning-practice" framework, aiming to elucidate the core pathways and differentiated strategies for soundscape-based mitigation. A multi-case qualitative design encompassed six rural destinations in China: Yuantang Terraces and Libo Zhangjiang (ecological), Yongding Tulou and Dangjia Village (cultural-heritage), and Moganshan and Zhanqi Village (suburban). Data were collected through participant observation (7-15 days per site), in-depth interviews (80 respondents; approximately 120,000 words), and textual analyses (327 User-Generated Content (UGC) items and official documents). The analysis followed a three-stage coding process using NVivo 12 until theoretical saturation was achieved. The results revealed a three-stage progressive pathway—sensory capital activation, cultural acoustics empowerment, and spatio-temporal fixation—embedded within a self-reinforcing feedback loop. At the sensory capital activation level, natural soundscapes generate use value through stress reduction and attention restoration, extending tourists’ average dwell time at Yuantang Terraces by 20 min. Humanistic soundscapes generate symbolic value through nostalgia and participatory engagement. Elderly tourists in Dangjia Village planned winter return visits triggered by traditional peddlers’ calls, while younger tourists developed a sense of belonging through interactive drum performances. Soundscapes also carry exchange value as information carriers: the "rice paddy frog calls" short video in Zhanqi Village directly prompted off-season bookings, while off-season mountain singing in Yongding Tulou encouraged off-peak recommendations. At the cultural acoustics empowerment level, local communities encode productive and everyday soundscapes (e.g., rammed earth chanting symbolizing solidarity and morning pestle sounds reflecting a grain-cherishing philosophy). Tourists decode these sounds through generational, urban-rural, and cultural distance lenses, thereby fostering deep place attachment. Drum sounds initially perceived as "noisy" were reinterpreted as “powerfully beautiful” after tourists learned about their historical military and harvest functions. This internalization translates into three behavioral outcomes: off-season intention (e.g., Moganshan winter bamboo-listening participants expressed a willingness to revisit during the off-season), consumption desire (e.g., purchasing soundscape-themed teaware as memory vessels), and enhanced sharing motivation (e.g., UGC related to weaving sounds achieved significantly higher interaction rates than conventional landscape photographs). At the spatio-temporal fixation level, spatial diversion during peak seasons achieves a geographical fix: zoning of Yuantang Terraces into quiet listening and interactive areas reduced core-area crowding by an estimated 28%, while drum sounds in Dangjia Village acted as an "acoustic lighthouse," guiding tourists toward peripheral alleys. Temporal staggering during the off-season achieves a temporal fix: Libo Zhangjiang’s "summer night firefly stream soundscape" narrative increased off-season visitation by 35%, while Moganshan’s soundscape membership system (off-season points redeemable for peak-season privileges) cultivated stable off-season visitation habits. This process forms a self-reinforcing loop—"deep experience → identity reinforcement → active off-peak behavior"—providing endogenous momentum for long-term visitor balance. The mechanism exhibits differentiated emphases across rural types: ecological villages prioritize use value and restorative experiences; cultural heritage villages emphasize symbolic value and cultural authenticity; and suburban villages prioritize exchange value and flexible scene construction. The essence of soundscape mitigation lies in a systematic socio-cultural process of "sensory activation → cultural identification → spatio-temporal restructuring," with its feedback loop ensuring sustainability. The theoretical contributions are twofold: first, the study introduces an auditory dimension into sensory capital theory by operationalizing a three-dimensional value system and demonstrating how soundscapes guide spatio-temporal decisions through physiological, emotional, and cognitive pathways, thereby challenging the visual-centric bias in tourism geography; second, it establishes a cultural interpretative pathway for spatio-temporal fixation theory by demonstrating that soundscape-based cultural narratives constitute a non-economic fix, thereby extending the theory’s application from capital logic to sensory-cultural governance.

The emergence of the information society has made two major limitations of traditional socio-economic increasingly evident: its emphasis on temporal and spatial dimensions while neglecting social relationships, and its focus on natural and economic capital while overlooking social capital. Using literature analysis and empirical evidence, this study examines the evolution of research from social capital theory to the practice of community construction and from social relationship network theory to the development living-circle planning. The results indicate the following: (1) The emergence of social capital theory reflects a renewed recognition of the importance of social communities. Trust mechanisms, participatory networks, and norms of reciprocity inherent in social capital contribute significantly to community construction and governance. Social relationship network theory focuses on connections and interactions among individuals and highlights the influence of network structure on individual behavior and decision making. Both social capital and social relationship networks operate at three levels: micro, meso, and macro. The interaction between these two dimensions continuously reshapes the social relationship system and constitutes an important form of “soft power” in the development of a high-quality society. (2) As innovative assets, social relationship networks derive their value from their capacity to transform social capital into innovation capital and to address uncertainties in innovation processes that formal markets or bureaucratic systems often struggle to manage, primarily through informal governance mechanisms. Innovation is therefore not merely a technical challenge but also a dynamic process involving the formation and evolution of social relationship networks. (3) The scarcity of social capital and the weakening of interpersonal relationships have resulted in significant social deficits and growing inequality. Strengthening interpersonal relationship networks, fostering supportive neighborhood mutual-assistance systems, cultivating a cohesive collective ethos, maintaining stable family lifestyles, and preserving a balanced relationship between market and family values are critical issues that must be addressed in the pursuit of high-quality social development in the new era of socialism with Chinese characteristics. Based on these findings, this study proposes several key pathways for reconstructing robust social relationship networks, including innovating institutional frameworks for network development, deepening the construction of resilient community commonwealths, optimizing the planning and design of urban social spaces, and strengthening social relationship networks through digital intelligence technologies. Finally, potential directions for future research in this field are outlined. Overall, this study proposes strategic goals, key tasks, and implementation pathways for reconstructing robust social relationship networks, offering both theoretical insights and practical guidance for high-quality social development.

The Central Urban Work Conference held in July 2025 indicated that China’s urbanization has entered a stage of stable development, placing new demands on the quality of the public space environment. As an important paradigm in contemporary urban spatial research, scene theory holds significant theoretical and practical value for reconstructing public space systems and stimulating the dynamics of urban-rural development. Based on a synthesis of the conceptual connotations of scene theory, this study employed CiteSpace and VOSviewer to conduct a bibliometric analysis and visual mapping of 289 studies on scene theory in public space published in the China National Knowledge Infrastructure(CNKI) and Web of Science databases from 2007 to 2024, to clarify research progress and identify future development trends. The findings are as follows: (1) From the perspective of research evolution, the development of this field can be broadly divided into three stages. From 2007 to 2015, the field was in an exploratory stage, with studies focusing primarily on preliminary discussions of cultural symbols and urban-rural spaces. From 2016 to 2021, it entered a stage of interdisciplinary integration, during which research shifted toward urban-rural spatial transformation and the expansion of localized applications. From 2022, the field entered a stage of rapid development, propelled by policy support that has advanced the reconstruction of cultural tourism and digital spaces. In comparison, international research began earlier and has maintained a relatively stable developmental trajectory. In contrast, domestic research received relatively limited attention before 2015, began to grow after 2016, and has accelerated since 2022, demonstrating strong developmental vitality. (2) From the perspective of research actors, international studies on scene theory and public space have emerged earlier and have generally incorporated scene theory as an analytical lens into topics such as urban studies, cultural consumption, and spatial governance, exhibiting clear interdisciplinary characteristics. Although domestic studies started later, the advancement of practical agendas, such as urban renewal, cultural-tourism integration, and digital governance, has gradually shifted the research focus from theoretical introduction to localized application and the construction of diversified scenes. (3) In terms of research hotspots and themes, the field has preliminarily formed a hotspot network centered on "scene theory-public space-scene making" and extended through themes such as "urban renewal-rural space-regional culture". However, a systematic and comprehensive theoretical framework is yet to be established. Major research themes were concentrated in areas such as public space development, public spaces in historic districts, urban public space renewal, scene-based construction of park cities, and the optimization of cultural scene spaces. Simultaneously, the research content showed a transition from single-dimensional planning and design toward the integration of multiple scene values. Overall, the evolution of this field has moved from "cultural symbol research" to "the expansion of localized applications", and further to "digital scene construction", indicating a shift in scholarly attention from explaining the physical form of space toward a people-centered emphasis on scene experience and value creation. Overall, research on public spaces from the perspective of scene theory relies predominantly on element identification and empirical induction. There remains a lack of systematic reviews and clear explanations regarding how scene elements are perceived in practice, and how such perceptions further influence the modes of public space use and the manifestation of public value. In response, this paper proposes an analytical framework of "scene elements-experience process-value outcomes". From the dimensions of elements, processes, and outcomes, it seeks to integrate and advance the directions for deepening scene theory in public space research, thereby enhancing its explanatory power and integrative capacity, and providing a new perspective for systematically understanding the comprehensive value of public space.

City diplomacy, as a vital driving force and dynamic manifestation of deepening ties between China and Global South nations, offers fresh perspectives for understanding the mechanisms of bilateral cross-border tourism. Utilizing panel data from China and Global South nations from 1992 to 2019, this study applies an extended gravity model and a two-way fixed-effects approach to explore the relationship. The findings reveal the following. (1) The scale of city diplomacy aligns positively with tourism flows, with sister-city partnerships fostering exchanges between China and Global South nations. (2) Effects are asymmetric, with stronger promotion of Chinese outbound travel than inbound visits. Each additional sister-city pair corresponds to an estimated 22,520 outbound trips from China and 11,840 trips from Global South countries. (3) Institutional distance influences this relationship negatively, more strongly for Chinese outbound tourism, reflecting sensitivity to institutional risks, while inbound visitors appear more influenced by cultural appeal. (4) City diplomacy operates through dual pathways, viz. political trust and economic symbiosis thereby shaping policy environments, trade, investment that support tourism. (5) Variation in economic development and industrial structures across Global South nations result in heterogeneous effects, with greater impact in lower-middle and upper-middle income countries. It most effevtively promotes outbound tourism from China to tourism-oriented destination, while exerting prominent pulling effect on inbound tourim to China from resource-rich nations. This study contributes to theory by employing the emerging perspective of city diplomacy to move beyond state-centered frameworks, broadening insight into the forces driving mechanisms of cross-border tourism. Practically, the findings offer empirical support for optimizing city twinning strategies and advancing tourism cooperation policies between China and Global South nations, while serving as a useful reference for advancing South-South collaboration.

As an important proponent of Mazu culture in South China, Nansha Tianhou Palace is undergoing a structural transformation from a “historical field,” centered on ritual practice and spatial order, to a “fluid field” shaped by digital media and platform-based dissemination. Against the backdrop of increasing cultural heritage mediatization, this study aims to explore how traditional religious spaces are reorganized in the interaction between physical settings and digital platforms and how cultural meanings are reconstructed through mediated communication processes. Specifically, this study considers tourist perception as a key analytical entry point for examining the relationship between spatial experiences and communications effectiveness. Methodologically, this study adopted a mixed qualitative and quantitative approach. A total of 3,838 items of user-generated content from Weibo and Xiaohongshu, spanning 2020 to 2025, were collected and analyzed, together with 22 semi-structured interviews involving tourists, local believers, and site managers. Grounded theory was employed to conduct open, axial, and selective coding, whereas word frequency and sentiment analyses were used to identify patterns in user perception and communications tendencies. Based on these methods, this study constructed an integrated analytical field transformation model consisting of four interrelated dimensions: content translation, spatial carriers, experiential feedback, and communications innovation. The findings revealed a significant shift in focus on cultural engagement. Tourists increasingly prioritize architectural landscapes, visual spectacles, and shareable content over their participation in core rituals. In this process, the cultural capital embedded in traditional belief systems is reconfigured into highly visualized and symbolic media content, leading to a transition in communications dynamics from offline place-based participation to online recirculation. Further analysis demonstrated that this transformation exhibits a structural tendency characterized by “visual enhancement and ritual attenuation.” Cultural meanings are often compressed into easily consumable landscape symbols, resulting in a disjunction between online popularity and offline religious experiences. Platform algorithms and traffic-driven mechanisms accelerate the conversion of cultural capital into media capital, shifting the logic of communications toward visibility, interactivity, and circulation. In addition, we identified the cyclical mechanism underlying this transformation. Offline ritual practices and spatial experiences serve as primary sources of cultural content, which is amplified and redistributed through digital platforms. User participation and feedback during sharing and reinterpretation generate new layers of meaning, which in turn reshape spatial organization and event planning at the physical site. This feedback loop constitutes a dynamic process of continuous field adjustment and evolution, highlighting the mutual construction of the physical and digital domains. Theoretically, this study contributes to the expansion of Bourdieu’s field theory by incorporating the concept of “media capital,” thereby providing an increasingly nuanced framework for understanding cultural transformation in the digital age. It further clarifies the mechanisms through which different forms of capital circulate and interact within hybrid cultural spaces: cultural, symbolic, and media. Practically, the findings offer insights for optimizing digital content design, spatial organization, and visitor experiences at cultural heritage sites. Generally, this study proposes a replicable analytical framework to examine how traditional cultural spaces negotiate authenticity, visibility, and communicative effectiveness under algorithm-driven dissemination.

Taiwan’s direct investment has long been a major contributor to regional economic development in Chinese mainland and an important source of cross-border capital. However, recent geopolitical and economic disruptions, including shifts in China–U.S. relations, the COVID-19 pandemic, and persistent cross-strait tensions, have accelerated the relocation of Taiwanese-funded enterprises, posing challenges to regional economic stability. Therefore, understanding how Taiwanese manufacturing firms strategically respond to external shocks is essential for advancing theoretical discussions and informing policy formulation. Guided by Global Production Network theory, particularly the concept of strategic coupling, this study examined how Taiwanese manufacturing enterprises interacted with regional institutional environments and how such interactions influenced their investment resilience. Employing a comparative case-study approach, we investigated the electronics and information manufacturing industry in Xiamen and the garment and accessories sector in Quanzhou. Data were obtained through questionnaires, in-depth interviews with 16 enterprises across multiple production-chain segments, and fieldwork with local industrial associations and government agencies. The findings yielded two major insights. First, investment resilience under external shocks is strongly shaped by the strategic coupling between firms and regional institutional settings. In Xiamen, electronics and information firms, characterized by high fixed-asset investment and technological intensity, displayed high spatial stickiness. Their deep integration with local institutions facilitated a transition from dependent to reciprocal coupling, supported by the localization of key production stages, technological upgrading, equipment modernization, and strengthened collaborations with universities and research institutes. In contrast, Quanzhou's garment and accessories manufacturers, operating with lighter assets, transitioned from dependent to cooperative coupling by leveraging the mature industrial ecosystem and strong market foundations of the region. These firms diversified beyond export-oriented models toward a balanced domestic–international market orientation, driven by the growth of e-commerce, live-streaming sales, and increased automation. Second, the degree of alignment between firm attributes and regional conditions plays a crucial role in shaping investment resilience and serves as a buffer against external disruptions. In Xiamen, compatibility with high-tech resources, university–industry linkages, and technology-oriented policy support enhanced regional embeddedness and spatial stickiness. In Quanzhou, alignment with extensive light-industry supply chains, abundant labor, and rapidly developing e-commerce platforms fostered greater flexibility and market responsiveness. These relational assets, developed through strategic coupling, reinforced both operational and strategic adaptability. Moreover, the investment resilience of Taiwanese enterprises exhibited multi-scalar characteristics: globally, firms reconfigured supply chains in response to U.S.–China trade tensions; regionally, cross-strait relations influenced technology transfer and talent flows; locally, deep embedding in innovation systems and institutional frameworks strengthened long-term rootedness. Theoretically, this study constructs an analytical framework that links micro-level firm strategies with macro-level investment resilience through the lens of strategic coupling. It elucidates how coupling evolves under external shocks and reveals the heterogeneous pathways through which industrial characteristics, regional resources, and institutional environments jointly shape resilience outcomes. These insights provide valuable implications for understanding cross-border investment dynamics in developing economies and guiding regional policy-making.

Along with climate change and rapid urbanization, recent urban rainstorm flood events have been presented as compound disasters characterized by rainfall-flood-urban inundation coupling, featuring rapid risk transmission, difficult forecasting, severe disaster situations, and a lack of defense standards. This study identified key scientific issues that need to be addressed in the study of urban rainstorm-flood compound disasters, including coupled integrated forecasting and rapid early warning methods based on the formation mechanism of urban rainstorm-flood compound disasters, the combination probability of urban rainstorm floods encountering each other, the return period and defense standard of compound disasters, the principle of risk transmission superposition, and the rapid diagnosis and suppression mechanism of urban rainstorm-flood compound disasters. Research content and technical routes oriented towards scientific problems were proposed. It is believed that solving the challenges of early warning for urban rainstorm-flood compound disasters, rapid risk diagnosis, and rapid suppression responses are crucial for the prevention and control of urban compound water disasters.

The relationship between prehistoric human activity and the natural environment has long been a central focus of archaeology. Uncovering the dynamic adaptation mechanisms of prehistoric agricultural societies under different topographical and hydrological conditions is of great scientific and practical importance. It deepens our understanding of past human-land interactions and provides insights for addressing rapid future climatic and environmental changes. As a key agricultural center in southwestern China, the Chengdu Plain, with its rich archaeological record spanning the Neolithic Guiyuanqiao Culture to the Qin-Han period, serves as an excellent case study for this research. This study investigated the spatiotemporal evolution of agricultural settlement patterns and their adaptation to topographical and hydrological conditions on the Chengdu Plain from the Guiyuanqiao Culture to the Qin-Han period. By integrating data from 223 archaeological sites with high-resolution digital elevation models (DEMs) and river vector data, we employed GIS-based spatial analysis and statistical methods. The key topographical (slope and elevation) and hydrological variables (distance to the nearest river and difference in elevation from the river) were extracted for each site. Statistical analyses, including probability cumulative distribution and period-wise comparative assessments, were conducted to analyze human preferences for settlement locations. Furthermore, to infer demographic trends, a regional radiocarbon (¹⁴C) probability density curve was used as a proxy for relative population changes and correlated with settlement patterns and agricultural information revealed by archaeobotanical evidence. The study revealed a phased settlement distribution pattern: initial occupation of peripheral uplands during the Guiyuanqiao period, southward expansion into the low-lying core plain during the Baodun period, northward contraction to the Yazi River Basin during the Sanxingdui period, renewed southward expansion during the Shierqiao period, and a more dispersed layout during the Qin-Han period. These shifts are closely associated with population pressure, flood risks, and migration events. Statistical results indicated that > 80% of the sites were located within 1,000 m of a river, and 74.7% had slopes < 3°, reflecting an overall preference for flat, river-proximate environments conducive to rice agriculture. However, significant variations were observed across these periods. Sites from the Guiyuanqiao Culture, linked to dryland farming populations migrating from the arid northwest, were predominantly located on higher-elevation slopes (average slope: 3.3°; average elevation: 516.3 m) and at greater distances from rivers (average distance: 1,221.7 m), indicating a strategy to avoid overly humid conditions. The Baodun period witnessed a surge in site numbers and expansion onto flatter terrain (average slope: 2.5°) alongside the dominance of rice cultivation to support population growth. However, this aggregation in low-lying areas increased vulnerability to floods from the Min River tributaries, likely prompting a northward relocation to the better-drained Yazi River Basin during the subsequent Sanxingdui period. Correspondingly, sites during this period showed a slight increase in the average slope and an increase in the proportion of dry crops (22.4%). The Shierqiao period saw renewed southward expansion and increased reliance on rice (82.7%) and renewed flood threats. During the Qin-Han period, the influx of northern migrants revitalized dry farming traditions, leading to settlement expansion on steeper slopes (average slope: 3.4°) and an increase in dry crop cultivation (22.3%). Rice agriculture persisted in the lowland plains and was supported by mature pond-field irrigation systems.

Global climate change and rapid urbanization have intensified the occurrence of extreme rainstorm events, and urban waterlogging has emerged as a critical disaster risk constraining the sustainable development of high-density cities, posing serious threats to life, property, and urban resilience. To characterize urban waterlogging risk in Shenzhen under different design rainstorm scenarios, this study constructed three representative scenarios with distinct return periods and rainfall characteristics—Zhengzhou “7·20”, Shenzhen “9·07” and Shenzhen “8·05” —using the two-dimensional hydrodynamic model LISFLOOD-FP and conducted systematic waterlogging simulations and exposure risk assessments of urban systems. Model validation using 183 historical waterlogging points demonstrated high reliability: within 50-m buffers of these points, maximum simulated water depths generally exceeded 0.3 m (with extreme values exceeding 10 m), effectively reproducing the spatial distribution and severity of severe waterlogging. The results indicate that waterlogging in Shenzhen exhibits a distinct spatial pattern characterized as “deeper in the west, shallower in the east; deeper in urban cores, shallower in suburbs,” driven by the “higher southeast, lower northwest” topography, high impervious surface coverage in western districts, and uneven drainage system loading. Among the three scenarios, the “7·20” design scenario poses the highest risk due to its high rainfall intensity, pronounced peak discharge, and extended duration, with areas experiencing water depths > 30 cm accounting for 26.55% of the study area. Specifically, more than 74,000 buildings and approximately 4.68 million people were exposed to water depth exceeding 1 m, and 46.76% of the total road network (8,966.25 km) was inundated. The “9·07” scenario is characterized by nocturnally concentrated short-duration heavy rainfall, resulting in localized water accumulation in low-lying areas such as Longgang. The “8·05” design scenario exhibits a multi-peak pattern with a pronounced surge and a mid-event rainfall lull that temporarily alleviates accumulation, producing an intermediate risk level relative to the other two scenarios. Critical infrastructure elements exhibit high sensitivity to water depth, with significant differences in risk response. Under the “7·20” design scenario, 1,028 medical institutions, 823 elderly and childcare facilities and 106 emergency shelters, were exposed to high risk, potentially compromising emergency medical services and vulnerable populations; more than eight hazardous chemical enterprises faced potential secondary disasters at water depths exceeding 0.5 m. Spatially, risk to critical infrastructure exhibits a pattern of “western concentration and eastern dispersion.” High-risk clusters are concentrated in Luohu and Longhua (medical and elderly-care facilities), Bao'an (moderate risk), and Nanshan, Luohu, and Guangming (hazardous chemical enterprises). Eastern districts exhibit generally low risk, with localized high-risk pockets confined to elderly-care facilities in Dapeng and Yantian. Futian District demonstrates the strongest protective performance, likely attributable to higher construction standards and more scientifically informed site selection. This study advances the literature by constructing cross-regional and locally representative design rainstorm scenarios and elucidating the coupling mechanism between rainfall characteristics and waterlogging risk in high-density urban environments. The findings provide a scientific basis for hierarchical disaster prevention planning and offer a transferable framework for waterlogging risk management in similar high-density cities nationwide.

The evolution of China’s traditional village protection policies reflects established processes of systemic change, from initial exploration and gradual construction to continuous optimization and deepening. Currently, within a critical period of economic transition from high-speed growth to high-quality development, China is seeking to define rules and internal logic regarding its policy evolution for the protection of traditional villages. This is important for promoting high-quality protection and sustainable development of traditional villages. Based on the theory of “attention allocation,” this study analyzed 107 laws, regulations, departmental rules, and other important policy documents formulated, promulgated, and implemented by the national legislative body (Central Committee of the Communist Party of China) or the highest state administrative organs from 1950 to 2023. By applying the three-dimensional analytical framework of “situation–attention–behavior,” this study investigated the stage characteristics and internal mechanisms of the evolution of China’s traditional village protection policies, which are jointly driven by policy situation, government attention allocation and policy behavior. The results showed that: (1) policy evolution is driven by specific situations and attention allocation, while the external manifestations of policy evolution include alterations in policy subjects, effectiveness levels, and policy tools triggered by policy behavior choices; (2) China’s traditional village protection policies have gone through four stages: (i) the policy incipience stage (1950-2001), (ii) the initial institutionalization stage (2002-2011), (iii) the upscaling and integration stage (2012-2019), and (iv) the paradigm transformation stage (2020-present). In the policy incipience stage, policy as a concept was primarily materialistic, with government attention focused on protecting cultural relics within villages. During the initial institutionalization stage, this concept remained materialistic, but government attention shifted to mainly focus on the preservation of cultural relics, historic and cultural villages, and intangible cultural heritage. As policies entered the upscaling and integration stage, the concept shifted to humanism, with government attention prioritizing both the protection of cultural relics and the preservation and utilization of traditional villages. In the paradigm transformation stage, policy evolved further into ecologism, where government attention expanded to include the protection of cultural relics, the preservation and utilization of traditional villages, and the demonstration of concentrated and contiguous preservation and utilization of traditional villages. The intensity and scope of government attention allocation followed an inverted U-shaped trend that peaked during the upscaling and integration phases. Driven by policy concepts and government attention allocation, the scope of policy issues has continuously expanded, and the relationships among issues have shifted from simple to complex; (3) during the evolution of traditional village protection policies, the number of policy entities and the degree of their cooperation gradually increased, peaking during the upscaling and integration stages, before declining during the paradigm transformation stage. Concurrently, the level of policy effectiveness continuously decreased, while policy tools evolved from reliance on environmental-type tools toward a diversified mix that combined environmental, supply-side, and demand-side tools. These findings contribute to understanding the internal mechanisms of the formulation and evolution of traditional village protection policies, identify the characteristics and shortcomings of current policies, and provide valuable references for future policy formulation and improvement.

Cities, especially megacities, are the destinations for new urban residents and young people in rapidly developing China. They are also the main areas where the child population is growing against a backdrop of population decline. The concept of child-friendly is gradually being noticed and valued. In this study, Changsha was chosen as an example of one of the first child-friendly construction demonstration cities in China based on the Child-Friendly Cities Initiative (CFCI) jointly launched by the United Nations Children’s Fund (UNICEF) and the United Nations Human Settlements Programme (UN-Habitat) in 1996. We constructed an evaluation index system for “child-friendly residential areas” using five aspects that meet the most basic needs of children: safety, accessibility, interest, growth, and sharing. The projection pursuit method, differentiation measure index, geographical detector, and other methods were used to calculate the child-friendliness of 1,131 residential communities in the urban area of Changsa, and the spatial differentiation characteristics of child-friendliness in these residential areas as well as their influencing factors were explored. The aim was to guide the planning and implementation of child-friendly cities in China at the residential space level, thereby forming a scientific and systematic local model. The following results were found: 1) The comprehensive child-friendliness of residential areas in Changsha varied significantly in different housing areas, showing an overall spatial pattern of “one center-multiple highland-low edge.” The central urban area in the eastern part of Changsha, the 2-kilometer area along the Xiangjiang River, and the newly developed urban subcenter had the highest child-friendliness, whereas the urban fringe areas and industrial zones were relatively less child-friendly. However, significant differences were observed within the central urban and old urban areas in the eastern part of Changsha, whereas new urban areas such as the Meixi Lake District showed a relatively balanced performance. 2) The spatial differentiation of each sub-dimension index of child-friendliness in residential areas had its own characteristics: safety was higher in the south and lower in the north; the distribution of interest was relatively balanced; the pattern of growth was obviously “high in the center and low at the edge”; and the sharing and accessibility aspects were positively correlated with the overall friendliness. The sub-dimensional indicators were closely related to the sequence of urban development, level of urban construction, supporting facilities of public services, and policy planning. 3) The child-friendliness of residential areas in Changsha was significantly influenced by both internal (e.g., housing prices, construction era, self-governance level, and property management grade) and external factors (e.g., demonstration effect and planning level). Additionally, an interaction enhancement effect among the factors was evident. High-quality housing and effective community management had a synergistic effect in improving child-friendliness. 4) Based on the analysis findings, the following policy suggestions are given: to build child-friendly living spaces, the top-level design of child-friendliness should be strengthened, child-friendly residential areas should be planned and constructed in accordance with local conditions, and the leading role of child-friendly demonstration communities must be enhanced.

National image represents the comprehensive power and influence of a country across multiple dimensions in the global arena. How a nation can simultaneously expand its overseas economic activities while gaining broad international recognition and cultivating a favorable national image has long been a central concern in both international political theory and practice. In this study, ten ASEAN countries were used in a regional case study of how China’s Outward Foreign Direct Investment (OFDI) affects its national image in the region. Using data from multiple sources, we constructed a 2003–2022 panel dataset covering China and the ten ASEAN countries and used a two-way fixed-effects model to empirically analyze the OFDI effects, underlying mechanisms, and nonlinear processes. The following results were found: 1) China’s OFDI significantly enhanced its national image in the ASEAN countries, indicating that Chinese firms abroad not only pursued economic gains but also played a crucial role in shaping evaluations of China by host countries. 2) The effect of China’s OFDI on national image varied with the host country income level, industrial structure, and religious-cultural context. The image-enhancing effect of OFDI was more pronounced in countries with lower–middle incomes. With regard to industrial structures, the positive effect diminished in highly industrialized economies. Culturally, Buddhist-majority countries generally exhibited a more favorable response to Chinese OFDI. 3) The mechanism through which China’s OFDI shaped national image operated at macro, meso, and micro levels. At the macro level, OFDI promoted green development and environmental improvement, enhancing institutional recognition of China’s development model. At the meso level, OFDI strengthened recognitions of China’s capabilities and cooperative value through technology diffusion, skills training, and industrial cooperation. At the micro level, OFDI directly affected individual-level perceptions and attributions by generating employment and alleviating poverty, thereby fostering positive emotional responses. Moreover, the positive image effect of OFDI became more pronounced when the number of inbound tourists from the host country exceeded a certain threshold. This study contributes to the literature in two main ways. First, it theoretically integrates essentialist and constructivist perspectives, addressing both the objective economic and social effects of OFDI and its role in cognitive construction through cross-national interactions, thereby systematically revealing the multidimensional mechanisms through which investment influences national image. Second, in terms of regional selection, the ten ASEAN countries constitute a distinctive “small yet comprehensive” setting for examining the impact of OFDI on national image. On the one hand, the region features a complex geopolitical landscape in which major powers such as China, the USA, and Japan interact and compete closely, providing a multifaceted real-world context for assessing how China’s OFDI contributes to building national image. On the other hand, ASEAN exhibits pronounced internal heterogeneity in levels of economic development, industrial structures, and cultural traditions, ranging from high-income service-oriented economies (e.g., Singapore) to low-income agriculture-based countries that retain strong traditional cultural characteristics (e.g., Laos). This diversity offers a rich empirical basis for investigating the heterogeneous effects of OFDI under different economic and cultural conditions and unpacking the macro-, meso-, and micro-level mechanisms through which these effects operate.

Rubber plantations in Southeast Asia and China’s Hainan Island face the threat of increasingly frequent compound drought and hot events (CDHEs). To overcome the biases of traditional meteorological indicators in reflecting ecological stress, we propose herein a method for quantifying environmental stress on the basis of the optimal growth threshold of gross primary productivity (GPP). By constructing three CDHE identification patterns for soil compound drought and hot events (SCDHEs), atmospheric compound drought and hot events (ACDHEs), and ecological compound drought and hot events (ECDHEs), we aimed to quantify the impact of such events on the GPP of rubber plantations on the basis of the degree of deviation from the optimal threshold. The following results were found: (1) The optimal growth threshold of rubber plantations exhibited significant latitudinal gradients and seasonality, with soil moisture thresholds throughout the year being higher and more stable in areas near the equator than in high-latitude regions, the latter of which showed obvious seasonal fluctuations. (2) Both the frequency and intensity of CDHEs showed increasing trends from 1982 to 2018, with ACDHEs exhibiting the highest growth rate (0.0216 events/year) and being mainly concentrated in the inland areas of the Indochina Peninsula. (3) The various CDHE identification patterns differed in their spatial applicability: the compound index of ACDHEs was applicable to the entire region, whereas those of SCDHEs and ECDHEs were primarily applicable to low-latitude regions, with their identification capabilities limited north of 10°N. (4) CDHEs caused significantly higher GPP losses in rubber plantations than did isolated drought or hot events (p < 0.001), with a damaged cell proportion of 70.64%, confirming the synergistic amplification effect of compound events. With regard to the significance of the individual factors, the inhibitory effect of drought stress on GPP was significantly stronger than that of hot stress (p < 0.001), and this difference was most pronounced in the SCDHE pattern. (5) The spatiotemporal differentiations of GPP loss were distinct and characterized by the most severe loss occurring from March to May in the 10°N–24°N region (daily average loss peaking at 1.469 g·C/m²). By contrast, within 10° of both the southern and northern latitudes, the loss peak occurred in August, reaching 48.763 and 55.862 g·C/m²), respectively. In conclusion, the method developed in this study for quantifying the impact of compound stress events on the basis of ecological thresholds can reveal regional variations in different indicators and provides a scientific basis for the climate-adaptive management of rubber plantations in Southeast Asia and China’s Hainan Island.

Coastal areas with dense populations and concentrated urban development face ecological and environmental issues such as pollution from emerging contaminants, with a large number of land-based pollutants being transported to the ocean via the land–sea interaction zone. Pharmaceutical and personal care products (PPCPs), which are not easily degraded in groundwater, have bioaccumulative and chronic toxicity properties that pose a threat to the health of ecosystems in the land–sea interaction zone. Moreover, PPCPs in this zone may be transported to the ocean via submarine groundwater discharge and can thereby potentially harm coastal aquatic organisms and the marine environment. Therefore, given that the coastal zone is a key node for land–sea integration and a strategic location for the scientific coordination of development and protection, further attention to its pollution by PPCPs is urgently required. The purpose of this study was to explore the behavioral characteristics of PPCPs in groundwater bodies in the land–ocean interzone of South China. In total, 60 groundwater samples were collected from Tangjiawan Town in Zhuhai City in September 2021, October 2022, and March 2023, respectively. The samples and data were analyzed using experimental and mathematical statistical methods, respectively. The following results were found: 1) During the wet season (April–October), six types of PPCPs were detected in the study area: sulfamethoxazole, sulfamethazine, sulfadimidine, cimaterol, carbamazepine, and caffeine. During the dry season (November–March of the following year), five types of PPCPs were detected: sulfamethoxazole, sulfadimidine, carbamazepine, caffeine, and atrazine. The concentrations of sulfamethoxazole, sulfamethazine, carbamazepine, and caffeine exhibited significant seasonal variations (P < 0.05). The rainfall-facilitated leaching or dilution of PPCPs in groundwater was the main cause of the seasonal differences in PPCP mass concentration. 2) Caffeine was a potential PPCP pollutant that could be discharged into the sea. The spatial variation in caffeine showed a decreasing trend as it moved from upstream to downstream of the watershed, nearing the sea. The flux of caffeine from submarine groundwater discharge into the sea along the unit length of the Zhuhai coastline was estimated to be approximately 33.2 μg/d. 3) The quantification of tritium (³H) isotopes in the groundwater revealed that the values at most sampling points were below 2 TU, indicating that the age of the groundwater can reach approximately 30 years. This is due to the mixing effect of residual groundwater in the aquifer medium and precipitation recharge. Using ³H dating software, a preliminary analysis of the changes in carbamazepine and caffeine contents in the groundwater over the past three decades revealed that the concentration of carbamazepine exhibited a decreasing trend, whereas that of caffeine showed a fluctuating downward trend, which was significantly influenced by annual precipitation and generally followed the same variation trend as annual precipitation. The results of this study can help to inform strategies for the prevention and management of groundwater pollution in the South China land–ocean interzone and provide a theoretical basis for the protection and sustainable utilization of groundwater resources.

With the pervasive penetration of artificial intelligence (AI) technologies, traditional paradigms of social space governance are undergoing a fundamental shift—from "digital governance" to "intelligent governance." In the governance space dimension, AI innovations such as AI-generated content (AIGC) and spatial intelligence have endowed digital twin spaces with unprecedented capabilities, transforming them from static reflections of physical reality into dynamic systems capable of proactive inference, simulation, and real-time optimization. This transition extends governance functions beyond mere representation to include predictive intervention and anticipatory regulation. On the dimension of governance subjects, algorithms have qualitatively mutated—from passive instruments of execution into "artificial agents" or "auxiliary governance actors" possessing autonomous learning, environmental adaptation, and predictive decision-making capacities. This mutation fosters an emergent symbiotic "human-machine collaboration," challenging established power structures and reconfiguring accountability boundaries. In this study, building upon this analysis of the data-to-intelligence governance transition, we examine—through case studies including Shanghai's "Quantum City" and Hangzhou's "City Brain"—the expansion logic and practical manifestations of multidimensional social space governance in the AI era. First, the governance space has expanded from a tripartite "physical-social-data" framework to a quadrilateral "physical-social-data-algorithm" structure. Spatial intelligence technologies and "real-world model" paradigms have positioned algorithms as the core of digital twin systems. Empowered by spatial intelligence, digital twin environments achieve heightened precision and synchronicity, enabling real-time and efficient interactions with physical spaces while demonstrating enhanced generative capacity and operational autonomy. These developments constitute the multidimensional spatial arena of public governance. Second, the governance subject has evolved from a "government-market-society" triadic relationship to a "government-market-society-intelligence" quadrilateral synergy. As AI agents gain greater autonomy, their subjectivity becomes increasingly manifested, elevating AI from a mere instrument to a co-constitutive governance actor that must operate in parallel with traditional subjects. This transformation necessitates fundamental theoretical and practical interpretations of the relationships among all governance stakeholders. This multidimensional expansion has engendered a series of novel challenges for public governance practices. First, AI and digital twin technologies have accelerated the convergence of the physical, social, and digital domains, yet this nascent "hybrid space" has precipitated profound normative conflicts in governance practices. Second, as AI transitions from a tool to an intelligent agent, algorithmic bias becomes more acute, and an "accountability vacuum" risk emerges within human-machine collaborative frameworks. Finally, persistent digital divides are metamorphosing into a new configuration—the "intelligence divide"—exacerbating social stratification. To address these emergent challenges, social space governance in the intelligence era requires innovative pathways. First, cross-spatial coordinative governance mechanisms must be constructed to enable the synergistic integration of virtual and physical domains, shifting from normative fragmentation to spatial order reconstruction. Second, a human-machine coordinative governance framework should be built upon technical foundations of "trustworthy AI" and institutional safeguards ensuring "ultimate human control." Third, governance must uphold a people-centered value orientation, ensuring that the benefits of intelligent governance are equally distributed across all citizens.

Artificial intelligence (AI) has profoundly reshaped human society and significantly impacted academic research. In the current era of intelligence, geography requires the development of new theoretical frameworks. By constructing and elaborating the theoretical framework of the "Poetics of Life," this study explores new pathways for geographical expression within the context of human-AI integration. The relationship between AI and humans manifests in four modes: tool, partner, friend, and soul. In the process of human-AI integration, place, body, and emotion emerge as three key vectors that are currently irreplaceable by AI. Drawing on existentialist philosophy, geographical poetics, and humanistic geography, and employing a digital autoethnographic approach, this article conducts an in-depth analysis of 122 songs co-created by Ye Chao(The first author) and AI and published on the personal WeChat Channel "Ye Shenxun." It compares the characteristics of individual writing with those of human-AI collaborative creation and summarizes their public communication effects. What distinguishes Poetics of Life in the new era from geographical poetics lies in three fundamental shifts: the creative subject has transformed from a solitary author to human-AI co-creation, the form of expression has expanded from single-text delivery to multisensory stimulation, and media dissemination has evolved from one-way output to multidimensional interaction. The song samples exhibited diverse styles and themes, reflecting the interplay of emotion, place, and AI, thereby highlighting the importance of new forms of geographical writing and expression in the intelligent age. In terms of communicative effects, a top-ten analysis of the texts revealed that audiences with a background in geography paid more attention to the mutual construction of place and everyday life, whereas other audiences focused more on emotional resonance. Surreal works, such as Chronicle of Light and Dust, demonstrate a cross-disciplinary, future-oriented dimension. The Poetics of Life in the intelligent age not only extends and deepens the humanistic tradition of geography but also provides new theoretical insights for interdisciplinary fields such as digital art and media geography. The expression, performance, and public communication of the Poetics of Life constitute key directions for future research.

Virtual cities and their built environments play a significant role in video games. Understanding their interactions with physical spaces and considering appropriate planning responses to this interaction are crucial for advancing digital twin technology and urban development in the digital age. Through qualitative and quantitative analyses of representative games such as Black Myth: Wukong, Genshin Impact, and SimCity, this study identifies a cyclical four-stage interaction pathway: (1) Perception: extraction of cultural symbols, (2) Re-organization: gaming-driven reconstruction, (3) Re-understanding: virtual urban areas understanding, and (4) Feedback: real-world application. Perception and Re-organization highlight that virtual space design does not merely replicate real-world spatial characteristics, but rather reorganizes them according to specific aesthetic and functional principles, thereby operationalizing Kevin Lynch's Image of the City theory. This design process is reflected in form and function perspectives. From a form-based perspective, games such as Genshin Impact exemplify how spatial distribution heterogeneity is evident, even in virtual environments. For example, an analysis of the in-game item distribution using the ht-index (value = 5) and log-log plots indicates that although the upper tail approximates a straight line, the lower tail exhibits a rapid decline, suggesting structured spatial heterogeneity. Similarly, a comparative analysis of Florence in video games versus its real-world counterpart supports the idea that virtual spaces selectively reinterpret, rather than mirror physical environments. From a functional perspective, city-building games, such as SimCity and Emperor: Rise of the Middle Kingdom, deconstruct cities into core elements (housing, industry, service facilities, geographic surroundings, and natural resources) and integrate these components through distinct game mechanics. Re-understanding and Feedback emphasize the influence of virtual cities on urban planning education and tourism. In particular, city-building games have a substantial, yet often underestimated, impact on urban planning practices, public participation, and collaborative projects. By lowering the knowledge barriers associated with professional urban planning, virtual cities offer an accessible platform for the public to engage with urban dynamics and foster a more informed and participatory planning approach. Similarly, video games significantly shape place perception in tourism. The immersive experiences provided by virtual cities can inspire players to visit real-world counterparts of game locations, resulting in phenomena such as 'anime pilgrimages.' Notable examples include the Fate series in Japan and the recent Black Myth: Wukong in China, both of which stimulated tourism by reinforcing place attachment through interactive storytelling and visual aesthetics. Based on this interaction pathway, we propose two planning recommendations. First, fostering interdisciplinary collaboration between urban planners, architectural scholars, and game designers can facilitate the dissemination of architectural and urban cultures on digital platforms. Second, leveraging the interactive and participatory nature of video games can enhance the public's understanding of urban systems, paving the way for game-based participatory planning and promoting multi-stakeholder engagement in urban development. This study contributes to emerging theoretical frameworks such as Digital Twins by elucidating the bidirectional relationship between physical and virtual urban spaces, thereby offering new insights into the evolving role of digital environments in shaping real-world urban experiences.

In China, urban development is transitioning from "incremental expansion" to "stock optimization." Due to this transition, a considerable number of urban villages in the country have evolved into spatially and culturally fragmented enclaves within the modern urban fabric, while retaining their unique socio-cultural structures. Focusing on this phenomenon, this study integrated scene and spatial production theories to systematically deconstruct the cultural logic and transformation pathways that underlay the spatial production of urban islands in China, while considering Chebei Village in Guangzhou as the study area. This region is characterized by cultural preservation amidst rapid urbanization. A mixed-methods approach was employed, including participatory observation, in-depth interviews, and multi-source textual analysis. The results revealed a dynamic correspondence mechanism comprising two core systems: a "cultural elements-cultural scenes-cultural spaces" system that formed a tripartite cultural logic system and a "material authenticity-institutional performance-spiritual resilience" system that formed a concrete spatial transformation pathway. The "cultural elements-cultural scenes-cultural spaces" system comprised three aspects: 1) cultural identity spaces shaped by the authenticity of material culture (e.g., dragon boat practices and ancestral halls) and sustained through everyday spatial practices of residents; 2) cultural exhibition spaces produced through the theatricality of institutional culture, wherein power entities (e.g., local government) employed institutional labeling and festive performances to symbolically reconstruct and commodify cultural symbols; and 3) cultural resilience spaces generated through the legitimacy of spiritual culture, wherein community innovation, emotional solidarity, and inclusive mechanisms (e.g., youth alliances and "spiritual naturalization" for migrants) fostered cultural adaptation and regeneration. The "material authenticity-institutional performance-spiritual resilience" system highlighted the importance of preserving physical heritage and authentic daily practices, leveraging institutional empowerment and staged cultural events to enhance visibility and economic value, and strengthening community-based innovation and reconstructed identities to ensure cultural adaptability and sustainable regeneration. The three spatial types interacted dynamically, driven by the three dimensions of Scene Theory (authenticity, theatricality, and legitimacy) and the three moments of Spatial Production Theory (spatial practice, representations of space, and representational spaces). The novelty of this study lies in the integration of the Scene and Spatial Production theories, providing an analytical framework that captures both the symbolic construction of cultural values and the socio-spatial processes of space production. This study addresses the gaps in the understanding of the endogenous cultural dynamics of urban islands, while offering evidence-based insights into culture-led urban regeneration, demonstrating how culturally stagnant enclaves can transform into resilient and actively engaged cultural spaces. Notably, Chebei Village provides a replicable and expandable model for balancing heritage preservation, economic vitality, and social inclusion within the context of urban regeneration, while presenting valuable empirical and strategic references for enhanced cultural governance in contemporary urban China.

The persistent escalation of great power rivalries and regional conflicts has elevated military factors as increasingly critical variables that shape geopolitical relations and international power dynamics. Conducting an in-depth analysis of the spatial dynamics and formation pathways of geopolitical military influence is therefore of paramount importance for optimizing the allocation of military resources. Building upon the identified gaps in the existing literature on geopolitical military influence, this study employed an index system construction approach that integrated methodologies such as standard deviational ellipse analysis and fuzzy-set qualitative comparative analysis. A preliminary evaluation framework for assessing geopolitical military influence was developed, and its spatial evolution patterns and multidimensional formation mechanisms were examined. The findings revealed the following: (1) Military capability—represented by military financing, personnel strength, and defense industrial production—constitutes the foundational prerequisite for the generation of geopolitical military influence. Military cooperation—encompassing defense collaboration, joint military exercises, and international arms trade—enables the expansion and outward projection of such influence through diverse operational modalities. Military deterrence mechanisms—including nuclear, air-based, and sea-based deterrence—serve as critical manifestations of a nation's strategic acumen and technological prowess, collectively projecting coercive power to deter adversarial states. (2) The global geomilitary landscape demonstrates a stable pattern of "one superpower, many strong powers," with the United States consistently maintaining its position as the most geopolitically influential military power. Concurrently, China and India exhibit significant upward trajectories, whereas Russia and the United Kingdom display declining trends. The dynamic shifts in national geomilitary powers have prompted a southeastward shift in the global power center, with China emerging as the principal driver of this movement. (3) The pathways to geomilitary power can be categorized into three types: synergistic pathways of military strength and cooperation, military cooperation-led pathways, and comprehensive pathways. The multi-condition configurational effects form a robust geomilitary power that cannot be achieved in the absence of core conditions or the presence of only auxiliary conditions. The evolutionary trajectory of a nation's geopolitical military influence progresses through distinct developmental stages—beginning with a military cooperation-led formation pathway, transitioning to a synergistic pathway combining military capability and cooperation, and ultimately ascending toward an integrated pathway. This escalating evolution maps the developmental trajectory through which states enhance their comprehensive national power and geopolitical military influence. This article's in-depth exploration of geopolitical and geomilitary power research not only enhances our understanding of the dynamic evolution of geomilitary power dynamics among different countries but also significantly enriches and expands the research scope of geopolitics and geopolitical military studies. This provides a crucial perspective for comprehending the transformation of the global geopolitical landscape.

Cross-border economic cooperation zones are vital platforms for China's economic and trade engagement with neighboring countries. It is imperative to clarify their spatial governance mechanisms to promote high-quality regional development and foster dual domestic–international circulation. Grounded in the theoretical perspective of new regionalism, this article constructs an analytical framework called the "Governance Magic Cube" to examine the governance mechanisms of cross-border economic cooperation zones. The framework explores four interrelated dimensions: spatial scale, governance evolution, multi-actor participation, and development effects. Taking the Mohan-Boten Cross-border Economic Cooperation Zone as a case study, this study conducted an empirical analysis of its spatial transformation, institutional restructuring, and actor interactions. Based on the policy milestones represented by the 2015 Joint Master Plan and the 2022 administrative transfer to Kunming, this study divides the Cooperation Zone's development trajectory into three stages: local, national, and international. Through semi-structured interviews, land-use data analysis, and multi-source documentary materials, the study provides an integrated interpretation of the zone's spatial dynamics and governance logic. The findings indicate that: 1) Spatial scale: The Mohan–Boten Cooperation Zone has undergone a substantive leap from a "marginal border port" to an "international node." Its spatial structure, initially characterized by a linear "corridor-style" pattern extending along the Kunming–Bangkok Highway, with the twin ports of Mohan and Boten as core anchors, is now evolving toward a more networked, accelerated spatial configuration. 2) Governance evolution: The cooperation zone has experienced a progressive shift from "locally led experimentation" to "national strategic coordination," and eventually toward "transnational nested collaboration." Through policy trial and error, institutional adjustment, and the consolidation of regulatory rules, a temporally nested governance mechanism has gradually emerged, facilitating a fundamental transformation in cross-border governance from administrative segmentation to institutional integration. 3) Multi-actor participation: The governance model has shifted from a single government-led approach to a more interactive configuration involving multiple actors, including national authorities, local governments, enterprises, and social organizations. This shift has led to an increasingly diverse and dynamic cross-border governance system, where inter-organizational collaboration has become more complex, fluid, and multidirectional. 4) Development effects: The cooperation zone has strengthened its role as a strategic hub within national and international networks by promoting the coordinated upgrading of industrial chains and efficient allocation of resources. As a result, it is steadily evolving into a key platform linking regional development with institutional innovation. Overall, the study argues that cross-border economic cooperation zones operate as open systems shaped by spatial proximity, institutional forces, and social networks. Their governance mechanisms exhibit phased transitions, structural reconfiguration, and actor collaboration emerging from the synergistic interaction of spatial expansion, institutional restructuring, and multi-actor engagement. This study enriches research on cross-border regional governance and offers new insights into the evolutionary pathways of such zones under multi-scale, multi-actor conditions. In practice, it highlights the need to strengthen coordination among spatial planning, institutional alignment, industrial organization, and social governance, and to promote a shift from infrastructure-driven growth to institutional synergy and functional deepening, thereby enhancing the strategic role of cooperation zones within China's broader opening-up framework.

Green technological innovation serves as the core driver for achieving economic green transformation and the strategic goals of the "dual carbon" initiative. Although its importance is widely recognized, previous research has predominantly focused on national- or macro-level analyses. There remains a lack of systematic and detailed characterization of the long-term spatial evolution of green technological innovation, including differences among subsectors and the heterogeneous effects of diverse driving factors. Therefore, this study aims to examine the long-term evolutionary characteristics of geographical agglomeration patterns of green technology innovation in China and to identify the key factors and mechanisms influencing their development, thereby providing empirical evidence for formulating differentiated and targeted regional innovation policies. Based on the World Intellectual Property Organization (WIPO) International Patent Classification (IPC) Green Inventory, this study identifies and utilizes China's green invention patent authorization data from 2002 to 2021. Employing methods such as the locational Gini coefficient and spatial autocorrelation analysis, this study systematically depicts the spatiotemporal evolution of innovation activities in green technology as a whole and across its subsectors. Building on this foundation, a two-way fixed-effects model is used to empirically test the impact of factors across the four dimensions—resource input, market demand, policy support, and openness to the outside world—on the innovation levels of green technology overall and its subsectors. The study reveals several interesting results. 1) From a temporal perspective, China's green technology innovation exhibits a three-stage pattern of "steady growth–gradual enhancement–rapid development," with overall scale expanding rapidly. Spatially, a pronounced gradient emerges: eastern > central > western > northeastern regions, with the East maintaining absolute leadership in both total volume and growth rate. Based on development pace, the green technological subsectors have differentiated into a "three-tier" structure. Among these, alternative energy production, energy conservation, emission reduction, waste management, administrative regulation and design technology collectively, forming the "four pillars," which hold the largest share and exert the strongest pull on the industry. Among these, energy conservation and emission reduction technologies exhibit the fastest growth, becoming the focal point in recent years. 2) Spatially, green technology innovation exhibits a high degree of geographic concentration, increasingly clustering in the eastern coastal regions, particularly the Yangtze River Delta, and forming a distinct "southeast–northwest" spatial differentiation. Innovation activity is significantly higher south of the Hu Huanyong Line than north of it. High-high clusters are visibly contracting toward the Yangtze River Delta, whereas low-low clusters are spreading contiguously across western regions. However, overall regional disparities show a converging trend. 3) From the perspective of driving mechanisms, green technology innovation is influenced by a combination of resource inputs, market demand, policy support, and openness to the outside world. Among these factors, innovation funding support and human resource investment are universally recognized as key drivers. Nevertheless, other factors exhibit significant heterogeneity and unevenness in their impact across different technological domains. Policies should be tailored to leverage the synergistic effects of diverse policy tools based on the specific technological attributes and developmental characteristics of each field. The contributions of this study are as follows: First, by utilizing long-term green patent data, it dynamically reveals the complex spatial evolution of green technological innovation, from widespread clustering to high-value polarization and low-value contiguous clusters, thereby deepening theoretical understanding in innovation geography. Second, it overcomes the research limitation of treating green technology as a homogeneous entity, empirically revealing the heterogeneity of driving factors across different subfields and providing new evidence for understanding the logic of diversified green innovation development. Third, based on these findings, it explicitly proposes a policy shift toward tiered approaches and precision governance, emphasizing the need for differentiated policies tailored to regional resource endowments and technological field attributes. This provides critical decision-making references for building a coordinated and efficient green innovation governance system.

Recently, the integration of Intangible Cultural Heritage (ICH) and tourism has generated new consumption hotspots that facilitate the transformation of cultural resources into cultural capital, producing notable economic and social benefits. Drawing on critical heritage studies, this research applies cultural capital theory and scale theory to examine Yingge Dance, a national-level ICH item originating from Chaoshan region (comprising 3 prefecture-level cities: Shantou, Jieyang and Chaozhou), China. Using participant observation and in-depth interviews, we explored the multi-scalar formation and scale transformation of cultural capital related to Yingge Dance. This study yielded three main findings. First, Yingge Dance embodies both cultural publicity and capital productivity. Its preservation and transmission depend on embodied practice, objectified transformation, and institutionalized support, reflecting a fusion of tradition and modernity as well as a symbiotic relationship between economy and culture. Second, at the individual scale, performers continually refine their bodily knowledge and skills in intergenerational practices, extending training and performance into broader community contexts. This process transforms Yingge Dance into cultural capital that fosters group cohesion and enhances community governance. At the regional scale, cultural tourism consumption and market participation accelerate the production of objectified cultural capital. Supported by local government initiatives, Yingge Dance becomes a form of urban cultural capital that stimulates tourism consumption and contributes to urban branding. At the national scale, China incorporates Yingge Dance into narratives of physical, moral, and aesthetic education, embedding it within cultural governance frameworks through top-down policy empowerment. This elevates Yingge Dance to national cultural capital that reflects cultural diversity and strengthens international competitiveness. Third, Yingge Dance has achieved the reproduction of the functions, values, and meanings by scaling up from group-level cultural capital to urban cultural capital and subsequently to national cultural capital. However, challenges emerge during this scaling-up process, including cognitive conflicts among stakeholders, blurred genre boundaries, uneven development, and diminishing authenticity. To address these issues, China promotes a scaling-down approach through policies and discursive frameworks to maintain the vitality of ICH transmission. This scaling down is reflected in the stewardship and empowerment of ICH bearers, incorporation of national ICH strategies into urban development agendas, and strengthening of local governments' narrative and discursive power. This study offers a critical perspective on understanding the practices and interactions of multiple actors in ICH inheritance. It also provides practical recommendations for cultural tourism development and the extraction of ICH value through the lens of cultural capital and scale theories.

Facilitating the social integration of the migrant population is a pivotal task in the comprehensive advancement of new urbanization. Nevertheless, this significant task is currently confronted with formidable challenges arising from the prevailing trend of unstable employment in the labor market. This paper introduces the concept of precarity, which has been the subject of extensive and in-depth discussion in the international academic community, constructs a comprehensive indicator system for assessing employment precarity, and reveals the intricate impact mechanism of employment precarity on the social integration of China's migrant population. Based on the China Migrants Dynamic Survey in 2017, the following primary conclusions were obtained through rigorous exploratory factor analysis and parallel multiple mediation effect models. Firstly, the overwhelming majority of the migrant population is in a state of varying degrees of unstable employment. When evaluating the comprehensive index of employment precarity for the migrant population from four key dimensions, employment status, contract nature, occupational industry type, and unit ownership, the value of 0.466 indicates an overall moderate level of precarity. The migrant population that fails to attain stable employment often finds itself in a disadvantaged position. These individuals typically seldom sign formal contracts, which means they lack the legal protection and stability that come with such contracts. They are concentrated in the secondary labor market, where low-threshold occupations and non-monopolistic industries prevail. Despite their arduous work, they can only earn meager wages, which severely restricts their standard of living and development opportunities. Secondly, the average level of social integration of the migrant population is 0.363. The integration levels of the economic, psychological, and behavioral dimensions are 0.102, 0.614, and 0.732, respectively. The low-level integration in the economic dimension is the primary bottleneck in the social integration process of the migrant population. Thirdly, the employment precarity of the migrant population has a significant direct negative impact on its level of social integration. It constrains social integration by influencing a series of material, social, and subjective psychological conditions. These include income stability, housing stability, social security level, local social network, local social participation, housing willingness, and settlement willingness. The indirect limiting effect accounts for 77.49% of the total limiting effect. Among the hypotheses proposed in this paper, the effect of the employment precarity–residence intention–social integration path is the most significant, and the effect of the employment precarity–income stability–social integration path is the weakest. However, the employment precarity–family migration–social integration path has not been verified and requires further in-depth exploration and elucidation. This paper enhances the indicator system for measuring employment instability, comprehensively demonstrating its characteristics such as high job-change frequency, lack of security, and disadvantaged position in the labor market. Simultaneously, it specifically reveals the impact path of employment instability on social integration. Finally, this paper introduces the concept of employment instability into domestic human geography research, offering a solid research foundation for understanding and addressing the challenges posed by instability to the social integration of the migrant population. At the practical level, in the context of employment instability becoming a trend of economic development, it is imperative to promote the social integration of the migrant population through policy and system linkages in employment, housing, social security, household registration, and other areas.

High-resolution records and fine structure comparisons between different climate proxies are invaluable for elucidating the detailed variations and mechanisms of the East Asian Summer Monsoon (EASM) intensity. Based on eight high-precision ²³⁰Th dates and 448 δ¹⁸O data from a stalagmite (YX53) collected from Yongxing Cave in the Shennongjia Forestry District, Hubei Province, China, this study reconstructed a high-resolution EASM evolution sequence spanning 52.45 to 64.44 ka BP. This sequence completely covers Dansgaard-Oeschger (DO) events 18 to 15, and partly covers DO14. This record not only reveals the rapid onset and gradual decline pattern of DO18 during the Marine Isotope Stage (MIS) 4/3 transition but also delineates the sub-millennial-scale internal oscillations within DO17a and two sub-oscillations during DO16a that are comparable in duration and intensity. It also clearly documents two precursor events (PEs), namely PE17 and PE16. The results demonstrated that the EASM intensity exhibited a one-to-one correspondence with the Greenland ice core record throughout the DO18–15 events. However, in the YX53 δ ¹⁸O, Arabian Sea albedo, SCH02 δ ¹⁸O, and Cariaco Basin albedo records, the intensities of the PE17 and PE16 events are consistently lower than those of the subsequent DO17a and DO16a events. In contrast, the Greenland ice core record shows that the intensities of the PE17 and PE16 events are comparable to those of the DO17a and DO16a events, respectively. Furthermore, the evolution of EASM intensity during the DO events exhibited notable similarities to low-latitude climate processes. During the onset and termination phases of the DO events, changes in the EASM intensity resembled the more gradual transitions that are characteristic of low-latitude records. However, within the DO events themselves, the EASM exhibited internal structures analogous to those observed in low-latitude processes, such as the two sub-oscillations during DO16a that are comparable in duration and intensity, and the rapid-onset–slow-termination transition pattern of DO18. These consistencies indicate a significant modulating influence of low-latitude processes on EASM intensity during the MIS4/3 transition. We propose that the Western Pacific Warm Pool (WPWP) may have influenced the pace of EASM variability and contributed to centennial-scale oscillations within DO events through mechanisms such as air-sea interactions. Based on a stalagmite δ ¹⁸O record from Shennongjia, this study reconstructs EASM variability during DO events 18 to 15. Through detailed comparisons and analyses of transitional events, we reveal the modulating role of low-latitude processes on the EASM during the MIS4/3 transition. These results suggest that while high-latitude processes primarily drive the initiation and termination of millennial-scale EASM enhancement events, low-latitude processes, which are likely influenced by the WPWP, may shape the intensity and internal structure of these enhancements within DO events.

In the context of an accelerating society, young individuals in contemporary cities face mounting psychological pressures and existential anxiety. This has led to an increasing demand for environments that offer therapeutic relief and emotional refuge. This study takes the "Time-Farm," an urban green space, as a case study to explore the construction of urban therapeutic landscapes, the perception of young individuals, and the ontological and epistemological foundations of healing. Drawing on Tim Ingold's dwelling perspective, this study examines epistemologies of human-nature relations, embodied and enmined practices, and the temporality of landscapes to propose a multidimensional analytical framework. This framework serves to interpret how landscapes can be healing for youth and offers a new explanatory approach for reconstructing subjectivity in an accelerated society. The findings suggest that therapeutic landscapes are not simply the result of static natural environments but are co-constructed through a relational epistemology that views human and non-human life as interdependent, cohabiting participants. In the Time-Farm, the therapeutic effect of space emerges from its founders' intentional rejection of anthropocentrism. Plants are not regarded as decorative objects but as co-dwelling beings with agency. Through sustained interaction and affective care, caregivers' non-representational practices fostered a shared coexistence epistemology that resonated with urban youths. As youth began to participate in the maintenance and experience of the space, their involvement signaled bodily engagement and an epistemic transformation: therapeutic feeling required the recognition of human–nature interdependence. This shift in understanding is a necessary precondition of ecological connections and emotional resonance. Moreover, the therapeutic process is deeply embedded in the convergence of embodied and enmined practices and temporal rhythms of the landscape. The young participants engaged in sensory-rich, emotionally resonant activities that activated bodily awareness and relational connections to a place. The therapeutic effect does not occur as an immediate experience but rather unfolds over time through repeated interactions, seasonal cycles, and the slow growth of living organisms. The temporality of the landscape mirrors the rhythms of individual transformations and supports sustained therapeutic effects. Theoretically, this study challenges the reductive paradigm that equates therapeutic effects solely with environmental conditions. Instead, it proposes a relational and procedural approach integrating epistemology, embodiment, and temporality. By employing Ingold's dwelling perspective, this study provides an interpretive tool rooted in environmental anthropology for understanding therapeutic landscapes. Practically, it offers insights for designing urban green spaces: therapeutic environments must move beyond the mere presence of greenery to foster relational understanding, embodied participation, and long-term interaction.As an urban green space, the Time-Farm demonstrates how therapeutic landscapes can be cultivated through cohabitative epistemology, integrated mind-body practices, and sustained care. The model of a "human-environment-life community" provides an ecologically holistic perspective on landscape-making and offers a fertile direction for theoretical innovation in future therapeutic landscape research.

With rapid urbanization, urban safety has become a critical issue in city governance. Among the various approaches, Crime Prevention Through Environmental Design (CPTED) has gained increasing attention owing to its effectiveness in reducing crime risk through physical environment interventions. This study systematically reviewed the development trajectory of CPTED practices in South Korea over the past four decades, dividing them into three distinct stages: initial conceptual introduction and early experimentation, formulation of guidelines and pilot implementation, and legislative revision and full-scale institutionalization. Each stage was analyzed in detail in terms of policy background, implementation strategies, and governance arrangements. Based on this review, this study constructed a framework illustrating the operational mechanism of CPTED in South Korea, highlighting the collaboration among national agencies (particularly the National Police Agency), local governments, academic institutions, and communities. The model emphasizes the importance of a standardized design process and case-based feedback to form a dynamic and iterative practice system. To demonstrate the practical application of this framework, this paper presents a detailed case study of the Yeomni-dong neighborhood in Seoul, one of the earliest CPTED pilot projects in South Korea. Through onsite assessments, risk mapping, participatory planning, and post-implementation evaluations, the project significantly improved community safety, reduced specific types of crime (such as robbery), and enhanced residents' sense of belonging and security. This case underscores the adaptability and effectiveness of CPTED principles in densely built East Asian urban contexts.The study also provides a concise overview of how CPTED-related principles have been applied in China across different administrative sectors, including the Ministry of Public Security's "Skynet Project," the Ministry of Housing and Urban-Rural Development's "Complete Residential Community Guidelines," and grassroots governance initiatives such as Zhejiang's "Neighborhood Watch" and Beijing's "Fengqiao Experience." Despite these efforts, challenges remain in China's current CPTED practices, including the lack of a unified standard system, fragmented departmental responsibilities, and insufficient integration of digital and physical safety strategies.Drawing on South Korea's institutional and practical experience, this study proposes four strategies for constructing a localized CPTED framework in China: (1) improving the legal and regulatory system by incorporating CPTED principles into national and local standards; (2) fostering cross-sector collaboration among planning, security, and governance bodies; (3) embedding CPTED assessments into urban health-check mechanisms to identify spatial safety risks; and (4) integrating CPTED principles into the entire process of urban renewal projects to promote sustainable and resilient urban environments. This study aims to provide theoretical insights and practical guidance for improving urban crime prevention strategies in China, contributing to the development of a more integrated, adaptive, and locally tailored CPTED system. It also offers valuable lessons for the convergence of spatial planning and public safety governance in rapidly urbanizing contexts.

To enhance ecological civilization, establishing a governance framework that reconciles the principles of financial sustainability with those of urban green development has been identified as an effective pathway for urban sustainability. Land finance constitutes a distinctive government revenue model in China, providing crucial support for accelerated urbanization and urban construction. Without alternative large-scale revenue sources for local governments, land finance continues to be an important source of off-budget revenue. Therefore, optimizing the use of land finance and leveraging its positive impact on sustainable urban development are crucial. The positive role of land finance in promoting urban green development is an effective means of advancing ecological civilization construction and high-quality urban development. Urban green spaces are pivotal elements of the urban ecological environment. Investigating the influence of land finance on urban green spaces is an important research area. This study employed panel data from 273 prefecture-level cities in China from 2007 to 2019 to systematically assess the impact of land finance on urban green spaces by utilizing the fixed effects and spatial Durbin models. Furthermore, it assessed the moderating effect of environmental governance in promoting land finance to support the improvement of urban green spaces based on the moderation effect model. The findings indicate that the impact of land finance on urban green space exhibits an inverted U-shaped pattern with a negative overall effect. However, the positive impact of land finance on urban green spaces is limited. Local governments' environmental governance exerted a significant positive moderating effect on the impact of land finance on urban green spaces. As environmental governance strengthens, the impact of land finance on urban green space shifts from negative to positive. This suggests that land finance can promote improvements in urban green spaces through high-level environmental governance. The coverage level of urban green spaces displayed spatial agglomeration characteristics, and land finance had a negative spatial spillover effect on urban green spaces. In addition, the moderating effect of environmental governance presented a positive spatial spillover effect. Consequently, the impacts of land finance and environmental governance on urban green spaces in economically and geographically adjacent cities must be considered. Subgroup analysis showed that the impact of land finance on urban greenspaces is more pronounced in cities located in the central and western regions. This study makes a significant contribution to the discussion on whether land finance can support the improvement of urban green spaces and how to promote the positive role of land finance in urban green development, and the positive role of environmental governance in facilitating the supportive role of land finance in promoting urban green development. This paper proposes policy suggestions on how to use land finance to enhance urban green spaces and provides new ideas for sustainable and green urban development.

Based on the investment path data of the top 100 benchmark enterprises of new quality productivity in 2024, according to the three-stage hierarchical affiliation model, the spatial network structure of new quality productivity in Chinese cities and its influencing factors are studied by using social network analysis, spatial analysis through geographic information system, and QAP(Quadratic Assignment Procedure) analysis. The findings of the study are as follows: (1) The spatial network of new quality productivity in Chinese cities involves a wide range of cities with a certain degree of two-way interaction, medium-to-high connectivity, and strong agglomeration. A connection between any two cities is typically achieved through a few nodes. Simultaneously, the network exhibits a small-world effect, forming several independent small groups or circles with high-frequency interactions. (2) The network first forms a national core skeleton with a triangle with "Beijing-Shanghai-Shenzhen" as the vertex. Furthermore, it expands to a diamond network connection pattern with "Beijing-Shanghai-Shenzhen-Chengdu" as the vertex, forming an obvious "core-edge" structure. Beijing plays a core guiding role in the allocation of new quality production factors, and Shanghai is the largest core to attract investment inflows. (3) The network consists mainly of cross-level connections, with high-level cities having substantial external spillovers and closer internal connections that are mainly responsible for the undertaking, and the internal connections are relatively loose. Additionally, the characteristics of internal and external connections differ considerably across the three major regions—East, Middle, and West. The eastern region has the closest internal connections and stronger external attraction and interactivity, forming a ladder-like network pattern. The Yangtze River Delta and Pearl River Delta urban agglomerations exhibit characteristics of cohesive development, whereas the Beijing-Tianjin-Hebei urban agglomeration shows characteristics of external development. (4) Economic scale, industrial structure, network popularization, institutional proximity, innovation output, and innovative industries were the most important factors affecting the spatial network structure of China's new urban quality productivity. They essentially reflect the spatial configuration logic and coordinated agglomeration law of new quality production factors, and embody the network construction logic of "spatial nesting-innovation drive-industrial collaboration." Spatial nesting provides the most basic geographical and institutional support for the flow of new quality production factors and interaction between cities. The innovation drive is the core driving force behind the construction of network structures, and the industrial collaboration mechanism promotes this network relationship based on space and innovation, moving towards a deeper level of functional integration and jointly shaping a multilevel, gradient, and efficient flow network pattern.
