摘　　要：采用以层次分析-模糊综合评价模型,对东辽河流域的水环境承载力进行评价。结果表明:东辽河流域水环境承载力整体处于"一般"水平,水资源现状、生态环境、社会经济状况对其的影响贡献程度分别为0.6337、0.1919、0.1744,其中年均供水量、水资源开发利用率和水污染指数对东辽河水环境承载力的影响最大,其影响贡献程度分别为0.3354、0.1699、0.1045。The water environmental carrying capacity of the Dongliao River Basin was assessed based on the analytic hierarchy process and fuzzy comprehensive evaluation model.The results show that the water environmental carrying capacity of the basin was at the middle level;the contribution rates of the status of water resources,the ecological environment,and the socioeconomic state to the water environmental carrying capacity of the basin were 0.6337,0.1919,and 0.1744,respectively;and the annual average output of the water supply,the utilization rate of water resources,and water pollution indices were the critical factors influencing the water environmental carrying capacity of the Dongliao River Basin,and their contribution rates were 0.3354,0.1699,and 0.1045,respectively.
