摘要
[目的]通过建立模型修复水生态系统,评价流域水环境质量,为生态系统修复提供实用工具。[方法]以涑水河流域为例,采用了层次分析法(AHP),同时运用模糊隶属函数和综合指数法对影响水质因子的各个指标进行综合评价分析,建立干旱和半干旱流域水环境质量健康评价体系及评价模型。[结果]涑水河流域2008—2011年水环境质量健康评价结果为Ⅲ级,状态一般,较健康,评价结果与实际生态情况相符。[结论]所建立的干旱和半干旱流域水环境质量健康评价体系是合理的,能满足流域水环境质量健康评价需要。
[Objective] The water quality of the river basin was evaluated through the establishment of related models in order to provide practical tool for ecosystem restoration. [Methods] Using analytic hierarchy process（AHP）, fuzzy membership function and comprehensive index method, taking Sushui river basin as a study area, factors that influences water quality indexes were evaluated comprehensively. Evaluation system of water environment quality and was established and the models of the environmental health in arid and semi arid river basin was illustrated. [Results] In Sushui river basin from 2008 to 2011, the water quality environment was categorized as grade Ⅲ, at a status of ordinary health. The evaluation results were commonly the real status. [Conclusion] The health evaluation system of water environment quality in that arid and semi arid river basin proved reasonable, can meet the needs of health assessment of water environment quality in river basin.
