Abstract:

China is comprehensively advancing the reform of land and space planning. The delineation of urban development boundaries is an important measure to scientifically guide the adjustment of land and space structures, and realize high-quality space development. At present, no scholar has used the knowledge map method to conduct a comprehensive analysis of the research on the development boundary of Chinese cities and towns. Therefore, based on the data on HowNet from 1996 to 2019, we use CiteSpace to create a knowledge map of China's urban development boundary research, and systematically categorize the research trends and development context. This article is expected to provide a new research perspective for the improvement of delineation accuracy and control effectiveness of urban development boundaries in the new era. The results show that the domestic development boundary research has gradually prospered, and cooperation among scholars has shown "integrated dispersion and partial closeness." However, there is inadequate cooperation among the relevant research institutions. In addition, the research hotspots are diverse and are guided by different national policies and regulations and time zones. This article divides China's development boundary research into four stages: theoretical exploration, deepening understanding, delineation exploration, and management. It shows that domestic development boundary research has evolved from focusing on controlling urban sprawl, to protecting cultivated land, ensuring ecological security for shaping beautiful land, controlling urban forms, promoting urban transformation, taking into account equal development rights, and ensuring sustainable urban development. Finally, we conducted an in-depth study and discussion on the delimitation and management of future development boundaries, adjustment and evaluation, and humanism. Based on our findings, we make the following five policy recommendations: improve the ecological compensation mechanism, delimit the development boundary based on the principle of ecological priority; unify the boundary delineation accuracy of each planning level; formulate diversified development and protection management and control models; implement the boundary trial period system to strengthen the flexibility of boundary management; and improve the people-oriented. The boundary of the center delimits the management system.
