[Objective] The aim was to assess the ecological civilization construction in urban agglomeration composed of Changsha,Zhuzhou and Xiangtan synthetically.[Method] By means of analytic hierarchy process,the assessment system of ecological civilization in Changsha,Zhuzhou and Xiangtan was established firstly,and then the ecological civilization construction in Changsha,Zhuzhou and Xiangtan was evaluated comprehensively,and the existing problems and causes of ecological civilization construction were analyzed,finally the corresponding suggestions and countermeasures were put forward.[Result] For natural subsystem and social subsystem,the comprehensive scores of Changsha,Zhuzhou and Xiangtan were 0.143 and 0.214,and Changsha had the highest scores (0.150 and 0.221),and next came Xiangtan (0.142 and 0.219),while the scores were the lowest in Zhuzhou (0.136 and 0.213).From economic subsystem,the comprehensive score of urban agglomeration composed of Changsha,Zhuzhou and Xiangtan was 0.216,and the maximum score appeared in Changsha (0.247),Zhuzhou the second (0.201),while Xiangtan owned the lowest score (0.197).In cultural subsystem,the comprehensive score of urban agglomeration was only 0.078 which was the lowest score among four subsystems,and it was related to its low weight.In addition,the scores of Changsha and Xiangtan took the first place (0.079),while it was lower in Zhuzhou (0.077).[Conclusion] The ecological civilization construction in Changsha,Zhuzhou and Xiangtan persisted at a higher level and developed well on the whole. 展开更多

The research purpose is to accurately reveal the temporal and spatial law of the urban expansion of Changsha-Zhuzhou-Xiangtan, one of the seven major urban agglomeration areas in China, and provide decision-making basis for the future urban construction land layout and regional development policy-making. Based on the night lighting data (DMSP/OLS), this paper extracts the boundary of the urban construction land of Changsha-Zhuzhou-Xiangtan urban agglomeration from 1993 to 2017, and quantitatively studies the spatial and temporal characteristics of the expansion of the metropolitan area in the past 25 years according to the methods of spatial expansion analysis, center of gravity migration measurement, landscape pattern index, spatial autocorrelation, etc. The results show that: 1) it is scientific and feasible to extract urban agglomeration construction land by the method of auxiliary data comparison for the study of urban expansion;2) the expansion of regional space in Changsha-Zhuzhou-Xiangtan metropolitan area shows a trend of “weakening first and strengthening later”. The construction land keeps increasing, and the expansion form gradually changes from extensive type to intensive type;3) the center of gravity of the metropolitan area fluctuated and repeated in part during the past 25 years, but it was always located in the municipal district of Changsha city. The eastern region, mainly Changsha city, was still the core area of urban agglomeration expansion;4) strengthening the territorial space protection and control of ecological green core in the metropolitan area is a key measure for the high-quality development of urban agglomeration. 展开更多

Natural resources and the environment,environmental capacity of China has been approaching the red alert,and long-term accumulation of ecological debt needs to be solved. The transformation of economic development mode and green economic development path are inevitable choices. The complexity and the pressureof the ecological environment governance force Changsha-Zhuzhou-Xiangtan region to change the ecological governance method. The " government-market-society" is taken as the overall framework,to build a diversified body of eco-environment collaborative governance platform. Through collaborative governance among governments,government-market collaborative governance and government-society collaborative governance,ecological capital stock is improvedin the quantity and quality,thus contributing to benigndevelopment of regional economy and society. 展开更多

The rationality of land use structure was evaluated with dynamic TOPSIS method based on changing data of land use from 2008 to 2011 in the Changsha-Zhuzhou-Xiangtan area. The results showed that during 2008- 2011,the rationality of land use structure was totally high,the dynamic value hi of Changsha,Zhuzhou,Xiangtan and the Changsha-Zhuzhou-Xiangtan area was 0. 7954,0. 7821,0. 8245 and0. 8186,respectively; the value Ci( tk) reflecting the rationality of land use structure at different time points was rapidly increased,and the gap between regions was not big and shrinking. According to the grey relational analysis,the change of different land use types had different effects on the rationality of land use structure: transportation land,the land for cities,towns and villages and the land for mining and industry are most highly correlated with the rationality of land use structure,while arable land,woodland,water area and water conservancy facility land have also an important impact on the rationality of land use structure; controlling the excessive growth of transportation land,the land for cities,towns and villages and the land for mining and industry,protecting arable land,forest land,water area and water conservancy facility land,and moderately increasing the garden plot,plays a decisive role in optimizing the land use structure in the Changsha-Zhuzhou-Xiangtan area. 展开更多
