摘　　要：沙颍河河南段是淮河污染最严重的一段,也是淮河治理工程的重中之重。本文选取最能反映沙颍河河南段污染情况的界首断面为代表断面,分析沙颍河河南段水质年内年际变化情况,并定性的分析了其主要影响因素。结果发现NH3-N和CODMn(高锰酸钾指数)是影响沙颍河河南段水质的主要指标,并且水质变化与小麦种植期、降雨、年内雨洪分布等因素关系密切,因此要在该区域大力发展生态农业,提高闸坝的科学调度水平以应对因暴雨带来的面源污染问题。The pollution in Henan reaches of Shayinghe River is the most serious section in the Huaihe River and is also the most important government of water pollution control project.This article selected the Jieshou cross section which could reflected the pollution situation in Henan reaches of Shayinghe River as the represent cross section,analyzed the annual changes of water quality and influence factors by qualitative.Through the analysis,it turned out that the NH3-N and CODMn(the potassium permanganate index) is the major effect indexes for water quality,and the water quality change is close with the wheat growing period,rainfall,the rain flood distribution et.al.So we must develop the ecological agriculture,enhance the scientific level of gate operation so as to deal with the surface source contamination concerning with the rainstorm.
