摘　　要：黄河陕西府谷段流经毛乌素沙漠边缘,生态环境脆弱,具有独特的结构和功能,准确了解地表水体中污染物的污染状况、污染来源是解决环境问题的关键。从2015年~2021年碛塄断面的历年监测数据来看,高锰酸盐指数、COD、BOD_(5)、溶解氧四项指标出现超标,水质定量变化趋势为显著变好。通过分析碛塄断面对应的汇水范围内入河排污口、重点污染源对断面水质的影响,结合上下游、左右岸的行业特征、面源分布,进行溯源分析,研究对于改善黄河中游水质和河流规划目标具有良好的支撑作用。The Fugu section of the Yellow River in Shaanxi province flows through the edge of Maowusu Desert.Its ecological environment is fragile,with unique structure and function.An accurate understanding of the pollution status and sources of pollutants in surface water is the key to solve environmental problems.According to the monitoring data of moraine section from 2015 to 2021,the four indexes of COD_(Mn),COD,BOD_(5) and DO exceeded the standard.The quantitative change trend of water quality was significantly better.By analyzing the influence of sewage outlets and key pollution sources on the water quality of the section,this paper carried out traceability analysis by combined with the industry characteristics and non-point source distribution of the upper and lower reaches,left and right banks.The study plays a good supporting role in improving the water quality and river planning objectives in the middle reaches of the Yellow River.
