标识指数法在黄河山东段水质评价中的应用李华栋*,宋颖(黄河水利委员会山东水文水资源局,济南250100)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(NH3-N)、砷(As)、铜(Cu)、总磷(TP)和生化需氧量(BOD5)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。关键词:水质评价;单因子水质标识指数法;综合水质标识指数;黄河山东段中图分类号:X824文献标志码:A文章编号:2096-2347(2023)01-0086-10收稿日期:2022-08-24作者简介:李华栋,工程师,主要从事水质监测、水质评价及实验室管理等工作。E-mail:1084301841@qq.com引用格式:李华栋,宋颖.标识指数法在黄河山东段水质评价中的应用[J].三峡生态环境监测,2023,8(1):86-95.Citationformat:LIHD,SONGY.ApplicationofidentificationindexmethodinwaterqualityassessmentofShandongreachesoftheYellowRiver[J].EcologyandEnvironmentalMonitoringofThreeGorges,2023,8(1):86-95.ApplicationofIdentificationIndexMethodinWaterQualityAssessmentofShandongReachesoftheYellowRiverLIHuadong*,SONGYing(ShandongBureauofHydrologyandWaterResourcesoftheYellowRiverWaterConservancyCommission,Jinan250100,China)Abstract:BasedonthewaterenvironmentstatusoftheShandongreachoftheYellowRiver,sixtypicalwaterqualityindexes,in⁃cludingCODCr,NH3-N,As,Cu,TPandBOD5,wereselected.Themethodofsingleandcomprehensiveidentificationindexwereap⁃pliedtoanalyzethewaterqualityatfivesectionsofmainstreaminShandongreachesoftheYellowRiverfrom2010to2019.Theresultsdemonstratedthattheoverallwaterqualityofeachsectionwasequaltoorbetterthantheobjectiverequirementsforthewa⁃terfunctionalarea.Butwhenevaluatingthewaterqualitybysinglepollutionindex,TPwasfoundtobethemainpollutionindex.Theevalutionresultsobtainedfromthemethodofcomprehensiveindentificationindexweresupe...
