摘　　要：根据陕西省吴起县自然、社会和经济等方面的特点,通过比较指标的使用频度、征询专家意见,建立了吴起县生态环境质量评价指标体系,应用层次分析法确定了指标的权重。在消除指标量纲的基础上,计算了吴起县1995年至2004年的生态环境质量指数,从自然环境、社会环境、经济环境三方面对该县生态环境质量10 a间的变化进行了定量评价与定性分析,以期为当地及黄土高原县域可持续发展提供有益参考。This study is based on the characteristics of nature, society, and economy of Wuqi County,Shaanxi Province. Through frequency analysis and expert consultation, the evaluation index system of eco- environment quality for Wuqi County is established and the weight of each index is calculated by using the method of analytic hierarchy process（AHP）. After eliminating the dimension influence, the eco-environment quality index for Wuqi County from 1995 to 2004 is calculated. In view of the natural eco-environment, social eco-environment, and economic eco-environment, the variation of eco-environmental quality of Wuqi county in the past ten years is qualitatively evaluated and quantitatively analyzed. The research work provides a reference for sustainable development of Wuqi County and the Loess Plateau.
