An evaluation index system for the eco-environment population carrying capacity of Wuan City is designed based on ecological footprint theory. Ecological footprint model is applied to analyze the eco-envi-ronment population carrying capacity in 2000-2010. The sustainable development stature and driving factors are analyzed with the help of SPSS.Results show that the contradiction between ecological footprint and eco-logical carrying capacity was more prominent in 2000-2007. After 2007, the contradiction was alleviated to-wards a sustainable development through the transformation of economic growth and the improved utilization of natural resources.The population carrying capacity was strongly influenced by the per capita fossil fuel footprint that is the main factor for the dynamic change of ecological carrying population in Wuan City.
