摘　　要：以淮河流域(阜阳段)3个监测断面2009—2018年近10年的水质监测结果为对象,采用单因子污染指数法与内梅罗污染指数法对水质情况进行评价,评价结果表明:王家坝监测断面水质2009—2018年均为Ⅲ类;张大桥监测断面前6年水质为劣Ⅴ类,2015—2017年变为Ⅳ类水质,2018年变为Ⅲ类水质;徐庄监测断面水质在2016年前除2009和2011年2年为Ⅴ类,其他几年均为Ⅳ类,2017和2018年分别为Ⅲ类和Ⅱ类水质,污染指标主要为氨氮和高锰酸盐指数。同时,以王家坝监测断面为代表,通过对其水质与自然因素、社会因素等相关性的分析,探讨水质状况的影响因素,结果表明河道水量和降水量对水质保持有促进作用,GDP与渔业产值对水质的提升也产生了积极作用。Taking the water monitoring results of three monitoring sections of Huaihe River in Fuyang during 2009-2018 as objects,the water quality situation was evaluated using the single factor index evaluation method and Nemerow multi-factor index method.The assessment results indicated that,water quality of Wangjiaba monitoring section was classⅢduring 2009-2018.Water quality of Zhangdaqiao monitoring section was inferior class V from 2009 to 2014,and it changed into classⅣfrom 2015 to 2017,at last it changed into classⅣin 2018.Water quality of Xuzhuang monitoring section was classⅤin 2009 and 2011,and was classⅣin 2010,2012-2016,and was classⅢas well as classⅡin 2017 and 2018 separately.The main pollution indicators were NH 3-N and COD Mn.At the same time,the related driving factors of water quality were analyzed relying on the correlation between water quality and natural factor as well as social factor.Represented by Wangjiaba monitoring section,the related driving factors were river water quantity,precipitation,GDP and fishery which had possitive impacts on water quality.
