摘　　要：为探究箕山河流域水质污染现状及成因,选设7处监测断面和6类水质评价因子,采用单因子评价法、综合污染指数法和3种不同算法的内梅罗污染指数法,对箕山河流域水质现状进行综合性评价。结果表明:7处监测断面主要超标因子是TN;COD、氨氮次之。基于单因子评价法和3种不同算法的内梅罗污染指数法进行水质分析,7处监测断面水质均属劣Ⅴ类,综合污染指数法所得各断面均属重度污染。根据水质现状分析结果对污染原因展开调查分析发现,流域水质在断面1、断面3和断面4处恶化明显,原因分别是城市生活源排口、工业园区出水、畜禽养殖+乡镇生活源。In order to explore the status and causes of water quality pollution in Jishan River basin,seven monitoring sections and six kinds of water quality evaluation factors were selected.The single factor evaluation method,comprehensive pollution index method and three different algorithms of Nemero pollution index method were combined to comprehensively evaluate the water quality of Jishan River basin.The results showed that TN was the main factor exceeding the standard,followed by COD and ammonia nitrogen.Water quality was analyzed based on the single factor evaluation method and the Nemerow pollution index method with three different algorithms.The water quality of the seven monitored sections was classified as poor classⅤ,and all the sections obtained by the comprehensive pollution index method were classified as severe pollution.According to the analysis results of current water quality,the pollution causes were investigated and analyzed,and it was found that the water quality of the watershed deteriorated significantly in sections 1,3 and 4,which were caused by the discharge of urban living source,the effluent of industrial park,and livestock and poultry breeding+rural living source.
