摘　　要：区域生态经济系统健康由多因素决定,通过评价县域生态经济系统健康状况,为县域生态环境的规划、管理和保护以及综合治理提供决策依据。从生态系统、社会经济系统、人类健康和政策4方面评价县域生态经济系统的健康程度,以"生态环境、自然资源、社会经济和可持续性"评价体系为基础,选择森林覆盖率、水土流失率、水环境指数、径流深、耕地坡度状况等29个评价指标,利用层次分析法和熵技术对徽县的3个水土保持功能分区进行生态系统健康评价。结果表明,该县3个水土保持功能区的生态经济系统基本处于健康或亚健康状态,但是Ⅰ区及Ⅱ区的社会经济发展和可持续性方面存在问题,应作相应调整。The healthy situation of a regional ecosystem is decided by multiple ingredients. Though evaluating the health of eco-economic system of Hui County, the decision will be supplied for eco-environment conservation plan. In this paper, the health degree was evaluated based on eco-system, socioeconomic system, human health and policy. Eco-environment, natural resource, socioeconomic system, and sustainability were chosen as the base of assessment system. The Eco-environment included coverage of forest, soil and water losses, index of water-environment, erosion modulus, depth of surface runoff and slope of farmland. Natural resource included water quantity per capita, farmland per capita, woodland per capita, net primary productivity （NPP）, soil organic matter content, meadow area of animal unit. Socioeconomic system included population density, urbanization rate, gross national product per capita, income per capita, Engel coefficient. Human health and policy included energy of consumption per capita, water usage quantity per capita, scientific persons in per ten thousand person, occupation ratio of third industry, eco-environment promotion, ecoenvironment management, satisfaction degree of public to environment, input of eco - management, reach standard degree of industrial waste disposal, usage degree of industrial solid waste matter, disposal degree of industrial discharge gas and input of education. The author created 29 indicators for quantitative expression and assessed the health of ecological environment in three areas by method of AHP （Analytic Hierarchy Process） and entropy production. The results show that the eco-economic system of three areas in Hui County is in status of health or inferior health. Some problems are occurred in sustainability of Ⅰ area and Ⅱ area.
