第42卷第4期2023年8月·水环境·几种地表水环境考核评价方法的比较研究以南京市为例谢鑫苗,陈明,柏松,郑玉涛,李敏(江苏省南京环境监测中心,南京210013)摘要:为比较水环境考核评价方法的适用性及优缺点,在分析几种常用评价方法的基础上,根据2021年1~10月南京市地表水例行监测数据,针对南京市地表水水质特点,采用单因子评价法、水质指数法和水环境综合评价指数法对南京市各行政区水环境质量进行评价,对不同方法评价结果进行比较分析。结果表明:水质指数法与水环境综合评价指数法排名结果基本相同,指数法与单因子评价法排名略有区别;单因子评价法与水质指数法、水环境综合评价指数法均呈显著相关,线性回归分析水环境综合评价指数法与单因子评价法相关性高于水质指数法;综合三种评价方法理论上的优缺点并结合环境管理需求,组合使用单因子评价法和水环境综合评价指数法进行水质评价,为进一步识别区域地表水水质差异,评价水环境治理成效等工作提供技术支撑。关�键词:地表水;水环境质量;考核评价中图分类号:X824ComparativeStudyofSeveralAssessmentMethodofSurfaceWaterEnvironmentXIEXin-miao,CHENMing,BOSong,ZHENGYu-tao,LIMin(JiangsuNanjingEnwironmentalMonitoringCenter,Nanjing210013,China)Abstract:Inordertocomparetheapplicability,advantagesanddisadvantagesofsomecommonmethodsforwaterenvironmentalqualityassessment,basedontheanalysisofseveralcommonlyusedassessmentmethods,accordingtothemonitoringdataandcharacteristicsinthesurfacewaterofNanjingfromJanuarytoOctober2021,thesinglefactorassessmentmethod,waterqualityindexmethodandwaterenvironmentcomprehensiveevaluationindexmethodwereusedtoevaluateWaterEnvironmentqualityofeachadministrativeregionofNanjing.Theevaluationresultsofdfferentmethodswerecomparedandanalyzed.Theresultsshowedthattherankingresultsofwaterqualityindexmethodandwaterenvironmentcomprehensiveevaluationindexmethodwerebasicallythesame,buttherankingofindexmethodandsinglefactorevaluationmethodwereslightlydifferent.Thesinglefactorevaluationmethodwassignificantlycorrelatedwiththewaterqualityindexmethodandthewaterenvironmentcomprehensiveevaluationindexmethod.Linearregressionanalysisshowedthatthecorrelationbetweenthesinglefacto...
