Based on the evolution analysis of urban ecosystem and its dissipative structure, this paper established an evaluation index system of urban ecosystem sustainable development capacity. The sustainable development capacity evaluation model of urban ecosystem was built based on the entropy change equation in the second law of thermodynamics and information entropy theory; taking Nanjing city as an example, this paper empirically studies the Nanjing’s urban ecosystem sustainable development capacity. The results showed that: between 2005 and 2013, Nanjing’s urban environmental pollution has been effectively eliminated; Nanjing’s urban ecosystem has developed in an orderly and healthy direction; the carrying capacity of Nanjing’s urban ecosystem has been showing an upward trend. The quality of Ecological environment has been improved and the ability of the urban ecosystem to support the urban socioeconomic ecosystem increased continuously.
