Abstract: The ecological civilization construction has become the focus of researchers, the government and the public recently. Therefore, it is of great necessity to evaluate the level of ecological civilization construction and elucidate the key restraining factors. Taking Jiangsu Province, a developed coastal province in eastern China, as the case area, the level of ecological civilization construction and key restraining factors were analyzed with the method of multiindex comprehensive evaluation. The index system was composed by five aspects, i.e., ecological economy, ecoenvironment, ecoliving, ecological culture and ecological institution. From previous index systems built by different researchers, government planning and reports, 147 factors were listed firstly. Based on the relevance, pertinence, applicability and availability of each factor on the evaluation of ecological civilization construction in Jiangsu Province, 22 factors were chosen as representing indicators in this research. The level of ecological civilization construction and the progress of 22 indicators were analyzed in 2007 and 2012. Results indicated that the level of ecological civilization construction increased rapidly after 2007, and the levels of ecological culture and ecoliving increased substantially. However, the progress of some factors from the aspects of ecological economy, ecoenvironment and ecological institution was slow. Regarding the ecological civilization construction, Jiangsu was at the uppermiddle location among the nation, but had some disadvantages in the aspects of ecological economy, ecological institution and ecoenvironment. It is concluded that a series of targeting measures should be adopted to promote the ecological civilization construction, such as promoting the transformation of development mode, strengthening eco-environment protection and perfecting ecological institutions.
