长三角城市群生态文明建设问题及潜力研究——基于5大城市群的比较

理清城市群的生态文明建设现状与问题，对于认清城市群下一步生态文明建设方向有着重要意义。通过复合生态系统理论和“PSR”模型构建生态文明评价指标体系，运用熵权TOPSIS法、协调度模型、耦合协调度模型、生态文明建设潜力模型对5大城市群生态文明建设现状进行评价，并总结归纳各城市群面临的问题。研究显示：（1）经济发展与生态保护之间的矛盾是当前长三角城市群生态文明建设的主要矛盾，整体上城市群的自然、经济、社会发展不协调；（2）部分地级市的生态文明建设存在盲目性或建设意识不强的情况，缺乏科学引导；（3）经济发达的地区具有更强的能动性，而协调发展的地区拥有更大的生态文明发展潜力。建议长三角城市群以科技创新为抓手，走经济与环境协调发展道路，率先支持上海、杭州等有条件的大城市成为示范城市，进而发挥带动作用。 关键词： 城市群；生态文明；潜力；PSR；复合生态系统

Problems and Potentiality of Ecological Civilization Construction in Yangtze River Delta Urban Agglomerations:Based on the Comparison of Five Major Urban Agglomerations

Clarifying the current situation and problems of ecological civilization construction is of great significance to recognize the next direction of that in the urban agglomeration.This paper evaluates the present situation of the ecological civilization construction and summarizes the problems which faced by the five urban agglomerations with the ecological civilization evaluation index system constructed by the compound ecosystem theory and "PSR" model.The methods include the entropy weight TOPSIS method,the coordination degree model,the coupling coordination degree model and the potential model of ecological civilization construction.Research shows:(1) The contradiction between economic development and ecological protection is the main contradiction of ecological civilization construction in Yangtze River Delta urban agglomeration.As a whole,the natural,economic and social development of the urban agglomeration is out of harmony.(2) There is blindness and weak construction consciousness of ecological civilization construction in some Prefectural-Level cities,which is the lack of scientific guidance.(3) There is stronger initiative in developed areas,while there is a greater potential for ecological civilization development in the coordinated developed region.It is suggested that the urban agglomeration in the Yangtze River Delta should focus on the science and technology innovation and take the path of coordinated development of economic and environment.It is so wise to support large cities like Shanghai and Hangzhou as a model city at first,then to realize their function of leading role.
