Abstract: 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.
