摘要：Urban ecological carrying capacity is an important standard to measure the sustainable development of urban ecology. In this paper, the evaluation index system of urban ecological carrying capacity is established from three aspects of the ecological elastic force, the supporting force of carrying media and the pressure of carrying objects. A new expression of state-space method for evaluation carrying capacity is presented innovatively. The new method and index system were applied to the evaluation of five provinces in the lower reaches of the Yangtze river. The results showed that the order of urban ecological carrying capacity was Jiangxi > Shanghai > Zhejiang > Jiangsu > Anhui. Finally, some suggestions for future development are put forward according to the evaluation results of each province, which is helpful to the formulation of ecological civilization construction policies.
