| Chongming Island has a good ecological environment and abundant natural resources, which is the reserve space of sustainable development in Shanghai. Based on the PSR model, this paper constructed Chongming island ecological environment evaluation index system, which contained 1 target, 3 elements and 22 evaluation indexes. Chongming island ecological environment index was obtained by the normalization of evaluation index and the weight calculation of each factor layer. Results show that, due to the implementation of Chongming ecological island construction plan, Chongming island ecological environment index showed a trend of increased from 0.57 by 2008 to 0.91 by 2015, the growth rate reached 60%, and ecological island construction process gradually tend to reach perfection, environmental protection had achieved remarkable results, and the sustainable and healthy development mode had been formed.
