    Tropical rubber plantation forest is the most important ecosystem in tropical China, and it plays an important and representative role in the study of solar radiation in tropical forest. It is necessary to study the radiation flux of rubber plantation forest because of the increasing questions about the ecological effects of the large-scale cultivation of rubber trees in tropical China. Solar radiation is the primary energy source for ecosystems, and the net radiation (NR) energy drives the ecosystem's life activities and energy flows. This study analyzed temporal variations and distributions of solar radiation and its components based on radiation fluxes observations on an iron tower of 50 m high in Hainan Island in 2010. The results showed that the diurnal variations in global solar radiation (DR), reflected radiation (UR) and NR all were represented by typical single-peak curves. Atmospheric inverse-radiation (DLR), forest long-wave radiation (ULR) and effective long-wave radiation (Ln) were represented by an undulating curve. Gross radiations, except Ln,in rainy season, were greater than those in dry season. Diurnal variation in the NR/DR ratio showed an inverted U-shaped curve while the Ln/DR and UR/DR ratios showed U-shaped curves. In addition, the relationship between the radiation fluxes was studied, too. And the annual mean reflectivity was 14.18%, the ratio of DLR/ULR 92.4% in 2010. Net radiation (NR) and global solar radiation (DR) was most closely related.

    In this paper the coastal zone to be studied is defined as the area along the shoreline at mean high tide level with a width of 2 km. The present situation of land use of the coastal zone and its problems are analyzed. The results show that:1) there are 228 166.44 hm2 of land resources in 12 coastal cities and counties, accounting for 6.63% of the total of the province; 2) both coastal land area and the farmland area in Wenchang rank first on the list of the 12 coastal cities and counties,while Sanya has the largest construction land area in coastal zone,Haikou the second; 3) the density of the construction land in coastal zone is high,which is 4.5 times the average of the province; 4) the land utilization efficiency of coastal zone is high,but contradiction between man and land becomes more and more prominent.And the land use structure needs to be optimized; 5) the intensive land use of coastal zone has led to obviously ecological degeneration, and this is particularly prominent in Wenchang,Wanning and Haikou.Aiming at those problems,the paper brings forward some countermeasures or suggestions for coastal zone on land use manner,land use degree,land use structure,land use distribution and land use benefit.

    Assessment of arable land productivity distribution is fundamental to agricultural growth and is of importance to development of agriculture with regional characteristics. This paper makes a comprehensive assessment of the arable land productivity of Chengmai County and Lingshui Li Autonomous County by building an indicator system for assessing arable land productivity, which includes eleven indicators and three sub-goals: soil physicochemical properties, soil nutrients, site conditions, and soil management, and applying Fuzzy Mathematics Theory to calculate the degree of membership and Analytic Hierarchy Process to determine the weight sum. The results show that: 1)Arable land soil productivities of Chengmai and Lingshui are moderate and the productivity of Chengmai is relatively higher; the distribution of parent materials and topographic conditions is the primary influential factor; 2)The distribution of arable land soil productivity is close to that of topographic conditions and river systems; productivities of valley floor plains, plains and piedmont plains are relatively higher than those of other areas; precipitation and topographic conditions are the determining factors of uneven distribution of arable land productivity in the study area.

    On the basis of four TM remote sensing imageries in 1996, 2000, 2005 and 2011, this paper studied the temporary and spatial changes of Guangzhou construction lands during the past 15 years by using ArcGIS spatial analysis tools. Results showed that the construction lands of Guangzhou city expanded about 413.44km2 during the past 15 years. The expansion speeds became faster and faster, belonging to the rapid expansion phase. The plaque number, average patch area, largest patch index and compactness of Guangzhou construction lands also increased year by year. The expansion types of construction lands in Zengcheng and Conghua Districts mainly belonged to sporadic and spread models, while the expansion type of construction lands in Guangzhou urban regions, Panyu, Nansha and Huadu District mainly belonged to filled and sprawl models. The main expansion directions of Guangzhou construction lands were toward Panyu and Nansha Districts in southeast and Huadu District in Northwest. Population growth, economic development, planning and policies, and traffic constructions were four major driving factors determining construction land expansion of Guangzhou city.

    Measurement of δ13C in Bivalve Shells: Implications for Dissolved Inorganic Carbon Reconstructions
    YAN Hui, YIN Xueyong
    2012, 32 (6):  613-617. 
    Abstract ( )   PDF (224KB) ( )   Save
    Stable isotope of Dissolved Inorganic Carbon is a very useful indicator for evaluation of carbon sources, sinks, and fluxes. Because of the difficulties in measurement of δ13CDIC, it is urgent to find a proxy of δ13CDIC. Stable carbon isotope in bivalve shells is a potential target. In this study, modern bivalve Corbicula is bred for experiment, and the results show that: δ13Cshell is highly correlated with δ13CDIC, and this significant correlation is due to markedly differences of δ13CDIC between the culture environment and the metabolic effects of the shells. δ13Cshell can not directly be used to quantitatively extract the δ13CDIC, but the high correlation between δ13Cshell and δ13CDIC implies that δ13Cshell can be used as a promising qualitative proxy of large scale variations in δ13CDIC. The future work should focus on the contribution of metabolic effects to δ13Cshell.

    Abstract ( )   PDF (586KB) ( )   Save
    The paper studies the villagers’ participation in the process of reconstruction of Urban Villages through a case study of Liede Village which is the first urban village to be reconstructed in Guangzhou. The authors empirically investigate the organization and participation of the villagers in the whole process of reconstruction of the village,and make conclusions on the villagers’ participation and analysis from the perspective of New Institution Economics. It is found that there exists serious imbalance of information between the Village Committee and normal villagers, and the normal villgers have seldom decision power. The normal villagers play a rather passive role of “being informed”.The main problem lies on the huge gap between the official institution arrangement and villagers’ demand and interest in participation in reconstruction of Liede Village. Therefore all kinds of informal participation means are created through internet and local network, and it directly leads to transition of institution. This article put forward some suggestions on the institution construction that would help to enhance the villagers’ participation according to the local resources, in order to promote the successful transition of the community governance.

    Transport is vital to regional development, which has impact not only on economy but also on society and politics. The level of regional transport consists of the interior connection and inter-regional accessibility, so the transport superiority can be quantified by multi-dimension system analysis. The system includes three dimensions: transport network density, influence degree of transport facilities and diffusion effect of the transport hubs. On the basis of mathematical evaluation model,this paper studies the spatial transport superiority in Guangdong Province, and some conclusions have been drawn. First, the transport superiority of the Pearl Delta is much higher than that of other areas in the province, where the three dimensions are all above the provincial average level. The transport superiority is higher on the east of the Pearl River mouth than on the west. Second, the spatial characteristic shows the transport superiority’s layer-loop structure. The superiority decreases gradually from the core (the Pearl River Delta) to the margin (the north mountain area), from the coast areas to the inland. Moreover, the study also reveals that there is a positive relation between transport superiority and economic development level. The transport superiority is proportionate to the economic development level that can be proved by the regression analysis with transport superiority degree and GDP per capita.

    Different origins of ethnic groups and geographical environment can directly affect the formation and distribution characteristics of language culture landscape, that is especially the case in an island.In this paper the statistical data of the village ethnic sourses of Weizhou Island in the Beibu Gulf are analysed. The results show that there are three dialect culture landscapes in the island, which are Hakka, Cantonese and Fujian dialects. They are distrubuted in the shapes of strip, patch and “dialect island”, presenting a pattern of concentric circles from the island centre to the coast. The distribution pattern of the dialect culture landscapes can be taken as a ‘living fossil’ which reflects the connotation of the diverse culture in Weizhou Island and can be for reference to understand the law of dialect propagation.

    There would be close internal relations between Danxia landform and Taoist culture. The authors summarized previous research results and made field investigation in a famous Taoist holy land–Longhushan Mountain in Jiangxi, where there is typical Danxia landform. Some preliminary conclusions are drawn as follows: Firstly, the red color of Danxia landform agrees with cultural psychology of Taoism which advocates the color of red and purple, and the combined landscapes of clean water with surrounding red Danxia hills caters for the ideology of Taoism which regards harmony between human and nature as the best. Secondly, the site of the Longhushan is in front of the Luxi River, surrounded by mountains and overlooking a large plain, such pattern is in accordance with the Geomantic Theory of Taoism. Thirdly, various exquisite Danxia micro-landforms provide many inspirations for Taoism myths. All those attract Taoism to select the Longhushan as a holy land to preach for more than 1900 years. At present, the Longhushan is one of the four holy Taoist mountains, a culture center of Taoism in China, making rich connotation and profound influence on Taoism culture.

    Coordinative urban-rural development has been identified to be the national strategy. Various efforts have been put into practices,and a series of achievements have been made by researchers. But still there are so many problems those need to be explored and solved. Taking Jiangbei District, a typical developed area in Chongqing City, as the study area, the authors make efforts to examine the measures put forward by government in the process of coordinating urban-rural development in Chongqing City. Those measures include the policies in economic development, social policy, and urban-rural plan, etc. Both positive and negative impacts of the measures on rural area are assessed, and a comprehensive model for the coordinative urban-rural development in Jiangbei District is constructed. The authors argue that at present the coordinative Urban-Rural development practice in Chongqing is of a government-dominant model, in which the market forces and public participation are relatively neglected.

    In this paper,ESRE(Economy-Society- Resource-Environment)complex system theory is used to study the coordinated development of the Nanliujiang Basin. For that purpose a coordinated development degree evaluation index system is constructed. The traditional measurement model of regional development is optimized.The coordinated development degrees of economy,society,resources and environment for upstream(Yulin), midstream(Bobai), and downstream(Beihai)subsystems of the Nanliujiang Basin are calculated. The result shows that in recent years the coordination level of the ESRE complex system of the Nanliujiang Basin basically remains stable,the upstream region and midstream region are in good state of coordination,and the downstream region achieves high quality state of coordination.With the accelerating process of industrialization in the basin,the pressure on ecological environment is also increasing.

    On the basis of visiting and investigating the historical residences in Shenzhen(one of the earliest areas striding forward to urbanization in China), the paper makes an analysis on protection and tourism esploitation of the residences. The result reveals that there exist six major issues in the current protection of historical residences: 1)the impact of urban remodeling; 2)the collapse of the original ecological benefit chain; 3)the lagged enact of regulations and legislation; 4)the confusion of property right structure; 5)people’s weak conscience of protecting historical residences; 6)people’s living habit alteration. Summing up the domestic and international experience and lessons about protection of historical residences, the author argues that much attention should be paid to the protection of the culture ecosystem integrity of the residences, a government-led and whole society involvement protection mechanism be established, the problems about property rights and funding be resolved, the protection measures be adapted to local conditions, and the protection be classified into different grades.

    Abstract ( )   PDF (120KB) ( )   Save
    With SPSS software, this paper makes a factorial analysis on the 11 major tourism economic indicators selected from the Guangxi 2010 Statistical Yearbook to get a comprehensive rank of tourism development level for 14 main cities in Guangxi, and combining with the GDP rank of those cities, the paper tries to examine the feacibility of the tourism regionalization in the Twelfth Five-Year Plan. From the results of the analysis, the authors argue that it would not be comprehensive to designate Guilin as the leading tourism city in the Plan; though Nanning, Guilin, Wuzhou and Beihai are planned to be the four major tourist distribution centers, Wuzhou does not conform with its reality; and also it would not be appropriate to designate the Red River Valley as one of the three international tourist destinations of Guangxi. However, the planning of "two Tourism Development belts and seven tourism Development regions" is in accord with actual situation. According to "Tourism - GDP" dimension, the authors consider that the 14 cities in Guangxi can be classified into 4 categories: category one, including Nanning, Guilin, Liuzhou and Baise, where both tourism and GDP develop well; category two, including Hechi and Beihai, where tourism develops well but economy poorly; category three, including Hezhou, Fangchenggang, Chongzuo, Laibin and Qinzhou, where both tourism and GDP develop poorly; category four, including Guigang, Wuzhou and Yulin, where tourism develops poorly but economy well. As the two most important developed tourism cities, Guilin and Nanning should serve as the northern and southern engines, respectively, to drive the overall tourism development of Guangxi according to their market positioning.

    The paper reviews the previous studies on mountain tourism from the perspective of tourism format. In the paper, the concept of mountain tourism format is defined, and five factors of mountain tourism format are generalized, which are: Resources of mountain tourism(R), Market demand(M), Ecological limitations(E), Industrial information(I), and Subject of profits(S).The constituents and actual bearers of the five factors are discussed. Tourism format can be classified into positive, neutral, and negative types in terms of its different functions in tourist planning.Mount Gongga is taken as an example to be studied in the paper. The authors consider that the Gongga could be divided into three areas: synthetic tourist area, supporting tourist area, and the area for scientific research. Moreover, the influential factors on mountain tourism format are analyzed and a tourism format plan for Mount Gongga is made.
