摘　　要：安阳市既是一个典型的工业城市又是一个资源型缺水城市,水环境压力较大。基于“十二五”至“十三五”汤河监测数据及第二次全国污染源普查数据,运用单因子评价、平均综合污染指数、秩相关系数、水环境承载力评价等方法对汤河水环境质量变化趋势、水环境承载力状态、主要污染因子及入汤河的工业污染源排放特征进行系统分析。结果表明:“十三五”期间汤河整体水质为中度污染,超标因子主要为化学需氧量、生化需氧量、高锰酸盐指数;2019至2020年汤河水环境承载状态为临界超载至未超载状态,工业排放源入卫河的支流排放量主要集中在汤河,其中总磷占总入卫河量的73.3%,化学需氧量占57.7%,总氮占54.6%,氨氮占50.5%。研究结果可为安阳市进一步加强区域水污染防治,解决汤河水环境问题提供技术支撑。Anyang city is not only a typical industrial city but also a resource-based water shortage city with great pressure of water environment.Based on the water quality monitoring data in the 12th Five-Year Plan period and the 13th Five-year Plan period,and second national pollution census data,using the single factor evaluation method,the average comprehensive pollution index method,Spearman correlation coefficient method,the water environment carrying capacity evaluation method to analyze the water quality change trend of Tanghe water,water environment carrying state,the main pollution factors and the emssion characteristics of industrial pollution source entering Tanghe river.The results showed that during the 13th Five-Year Plan period,the overall water quality of Tanghe river was moderately polluted,and the factors exceeding the standard were chemical oxygen demand,biochemical oxygen demand and permanganate index.From 2019 to 2020,the water environment carrying capacity state of Tanghe River ranged from critical overload to non-overload.The tributaries of industrial discharge sources into Weihe River were mainly concentrated in Tanghe River,of which the total phosphorus,chemical oxygen demand,total nitrogen and ammonia nitrogen accounted for 73.3%,57.7%,54.6%and 50.5%,respectively.The results can provide technical support for Anyang city to further strengthen pollution prevention and control of regional water and solve water environment problems of Tanghe River.
