Abstract: The index system for urban ecosystem health assessment was established in terms of natural ecosystem,social ecosystem and economic ecosystem on the basis of the conception and connotation of urban ecosystem health. Analytic Hierarchy Process (AHP) and Fuzzy Mathematics were applied to establish the assessment model. Nineteen districts and counties in the Three-Gorges Eco-economic Region in Chongqing were taken as a case study. Results reveal that the ecosystems in Fengjie,Wushan,Wuxi,and Chengkou were assessed to be unhealthy. The ecosystems in Wanzhou,Zhongxian,Fengdu,Wulong,Shizhu,Dianjiang,Liangping,Kaixian,and Yunyan were sub-healthy,and those in Xiushan,Youyang,Qianjiang,and Pengshui belong to healthy grade. The countywide ecosystem health in the region was obtained,which provides scientific basis for its sustainable development.

Key words: countywide ecosystem health, assessment index, assessment model, Three Gorges Reservoir area, eco-economic region
