The results showed that the per capita ecological deficit of Xuchang was 1.207733hm2, 1.297217 hm2 and 1.413993 hm2 respectively in 2005, 2008 and 2010, which exceeded the ecological carrying capacity of Xuchang City. The development of Xuchang was in an unsustainable state of development, and the ecological deficit gradually Showing an increasing trend, and thus for the sustainable development of ecological Xuchang put forward substantive basis and recommendations.
