Abstract
According to the policy-decision of ecological island construction, and based on the 1998-2004 statistic yearbooks of Chongming Island and the investigation in 2005-2006, the evaluation index system of ecological carrying capacity of Chongming Island, Shanghai was established , which included one overall objective, 3 sub-objectives, and 41 indices. AHP mediod was used to evaluate the weights, State-Space Model was used to calculate ecological carrying capacity , and GIS spatial interpolation was used to analyze the spatial differentiation of ecological carrying capacity. The results showed that the overall ecological carrying capacity of Chongming Island was high, the environmental carrying capacity and resources supplying ability were good, while the human supporting ability was bad. Different function areas had different ecological carrying capacity, and various industries should be developed in accordance with their own practical status.
