[Objective] Taking Jiangsu Province as the research object

the ecological carrying capacity during 2001-2005 was evaluated according to its resource endowment and the degree of obstacle was diagnosed in order to provide scientific basis for the promotion of ecological bearing capacity in the area.[Methods] The DPSIR was used to construct and establish index system and then the index weights were assigned by the entropy weight method

the TOPSIS analysis method and obstacle degree model were applied for empirical analysis.[Results] The ecological carrying capacity of Jiangsu Province indicated a "N" shaped trend evolution

and the comprehensive closeness was at the poor stage. From the perspective of classification indicators

the pressure

driving and response subsystem evaluation index experienced different levels of upward trend while the evaluation index of subsystem was a downward trend

station subsystem remains stable. From the diagnostic result of obstacle degree

the response subsystem is one of the main factors that affect the ecological carrying capacity of Jiangsu Province.[Conclusion] The coupling and coordination degree of society

economy and ecology is relatively low in Jiangsu Province. It should put forward increasing investment in environmental finance

improving infrastructure construction

strengthening the construction of ecological civilization system and expanding the space for ecological development

so as to promote the improvement of ecological carrying capacity in Jiangsu Province.
