摘　　要：为了解年楚河中下游区域水质现状,采用单因子污染指数法、综合污染指数法和灰色关联法对年楚河中下游区域10个监测断面水质进行了分析评价。结果表明:年楚河中下游区域各监测断面综合水质较好,各评价指标均满足《地表水环境质量标准》(GB 3838-2002)Ⅲ类水水质标准;年楚河中下游区域水环境质量整体较好,综合水质为清洁、为Ⅰ类水,区域水环境受外环境影响较小。In order to understand the current status of water quality in the middle and lower reaches of Nyangchu River, this article analyzed and assessed the water environmental quality of 10 monitoring sections in the middle and lower reaches of the Nyangchu River by using single factor pollution index method, comprehensive pollution index method and Grey-relating analysis method. The results showed that the comprehensive water quality of each monitoring section in the middle and lower reaches of the Nyangchu River is good, and all evaluation indicators meet the Class Ⅲ of "Surface Water Environmental Quality Standard"(GB 3838-2002);the water environment quality of the middle and lower reaches of the Nyangchu River is generally good. The water quality is clean and Class Ⅰ water, and the regional water environment is less affected by the external environment.
