新疆玛纳斯河流域绿洲生态安全评价

利用层次分析法和模糊综合评判法建立了生态安全评价指标体系，从水资源、环境和社会经济3个方面选取了18个评价指标对2006年新疆玛纳斯河流域绿洲生态安全进行了综合评价.结果表明：2006年，研究区生态状况处于基本安全水平，其隶属度值为0.3347，综合评分值为0.551；水资源安全指数和社会经济指数分别处于比较安全和非常安全水平，而环境安全指数则处于不安全水平状态.水资源是绿洲实现可持续发展的保障，社会经济指数和环境安全指数展示了绿洲的发展水平和环境状况，三因素极大程度上决定了绿洲的生态安全水平.

Ecological safety assessment of Manas River Basin oasis, Xinjiang

By using analytic hierarchy process and fuzzy comprehensive evaluation,an index system for ecological safety assessment was built,and 18 indices in the aspects of water resource,environment,and social economy were selected to assess the ecological safety of Manas River Basin oasis in2006.In the study area,the ecological situation in 2006 was basically safe,with the membership degree being 0.3347 and the integrated evaluation score being 0.551.The water resource safety index,social economy index,and environmental safety index were in the levels of relatively safe,extremely safe,and unsafe,respectively.Water resource index could represent the sustainable development degree of oasis,while social economy index and environment safety index could indicate the oasis development level and environment situation,respectively.These three indices could most reflect the ecological safety level of the oasis.
