摘要: 以生态保护优先机制为导向,从环境保护利用、经济绿色发展、社会和谐进步3个方面选择23个指标构建重点生态功能区绿色发展绩效评价体系,并以三峡库区为例,整合熵权法与专家评分法计算其2000~2020年绿色发展绩效,分析环境、经济、社会系统发展绩效及耦合协调度,并探索多维时空效应。研究发现:三峡库区绿色发展绩效在0.3~0.5之间,总体水平不高,但逐年稳步提升;环境保护利用绩效对绿色发展绩效贡献最大,社会和谐进步绩效贡献次之;库腹绿色发展绩效领先,库尾次之,库首较低,区域差异总体在缩小;时空格局呈现出“全面提升,七星引领”的演化特征,表现出显著空间正相关,但空间集聚性在减弱;三峡库区环境、经济、社会系统耦合度高,但耦合协调发展度低,复合生态系统处于一种低水平的协调发展。

Abstract: Guided by the principle of prioritizing ecological protection, this study developed an evaluation system of green development performance in key eco-function areas by selecting 23 indicators from environmental protection and utilization, the green development of economy and social harmony and progress. Based on the evaluation system, the green development performance (2000-2020) in the Three Gorges Reservoir Area was evaluated by combining entropy weighting method and expert scoring method. Also, this study explored the multi-dimensional space-time effects and analyzed the development performance of the environmental system, economic system and social system in the Three Gorges Reservoir Area and their coupling coordination degree. It was found that the score of the green development performance in the Three Gorges Reservoir Area was between 0.3 and 0.5, which was not high in general but it was steadily increasing with time. Environmental protection and utilization contributed the most to the green development performance, followed by the social harmony and progress. The green development performance in the belly section was the highest, followed by the tail and head section, It was found that the regional deviation was reducing. Regarding the spatial-temporal pattern, the green development performance featured a rising trend with seven regions in the lead, showing a positive spatial correlation but a loose spatial agglomeration. Although the coupling degree between the environmental, economic and social systems was high, the coupling coordination degree was limited and thus the complex ecosystem was in a low level of coordinated development.
