The main criteria restricting the UWEC level of UAs in the Yangtze River Delta were D and E, while E and F were the main restricting criteria for the UWEC level of UAs in the Middle Reaches of the Yangtze River and Cheng-Yu District. The results presented that the UWEC level of UAs gradually increased along the Yangtze River from west to east, showing obvious spatial differences. In our research, three major urban agglomerations (UAs) in Yangtze River Economic Belt (YREB) were chosen to be the study area.
The evaluation system contains 20 indicators selected from six criterion layers: water resources utilization (A, evaluating the efficiency of industrial, agricultural, domestic and public water use), water security assurance (B, evaluating the flood control, drainage and drinking water safety), water environmental protection (C, evaluating the water environment quality and water pollution prevention), water ecological restoration (D, evaluating the health of regional water ecosystem), water culture system (E, evaluating the inheritance of water culture and the popularization of UWEC awareness) and water management institution (F, evaluating the implementation of management systems). This paper introduced a composite index to characterize the Urban Water Ecological Civilization (UWEC) and established an evaluation index system for UWEC based on a multicriteria analytical framework. “Water Ecological Civilization” is a vital part of “Ecological Civilization”. “Ecological Civilization” is a term that demonstrates the strategy to achieve the win-win goal of economic development and eco-environment protection. Urbanization and economic development pose a challenge to the water ecological environment of cities.
