摘　　要：根据黄河山东段的水环境状况,选取化学需氧量(CODCr)、氨氮(NH_(3)-N)、砷(As)、铜(Cu)、总磷(TP)和生化需氧量(BOD_(5))6个典型水质指标,对2010—2019年黄河山东段干流5个断面的水质用单因子水质标识指数法和综合水质标识指数法进行评价。结果表明:黄河山东段各断面的综合水质类别均达到或优于功能区的目标要求,但对单项污染指标进行评价时发现,黄河山东段干流各断面主要存在的污染指标因子为TP。从评价结果来看,单因子标识指数法评价结果比综合水质标识指数法评价结果要差,而综合水质标识指数法能客观反映河流综合水质状况。Based on the water environment status of the Shandong reach of the Yellow River,six typical water quality indexes,including CODCr,NH_(3)-N,As,Cu,TP and BOD_(5),were selected.The method of single and comprehensive identification index were applied to analyze the water quality at five sections of main stream in Shandong reaches of the Yellow River from 2010 to 2019.The results demonstrated that the overall water quality of each section was equal to or better than the objective requirements for the water functional area.But when evaluating the water quality by single pollution index,TP was found to be the main pollution index.The evalution results obtained from the method of comprehensive indentification index were superior to those from the single index method,suggesting that the comperhensive method can better and objectively reflect the overall water quality.
