摘　　要：通过分析茫溪河污染源统计数据,计算污染负荷量,采用源强系数法估算茫溪河各类污染物的入河量,结合水质监测数据,评价水环境质量,分析各个污染物的时空分布特征,识别水环境问题,为开展区域水环境治理及水生态修复提供技术支撑。By analyzing statistical data of pollution sources in Mangxi River,pollution load is calculated and discharge coefficient method is used to estimate the amount of all kinds of pollutants into the river in Mangxi River.Combined with water quality monitoring data,water environment quality is evaluated,spatial and temporal distribution characteristics of each pollutant are analyzed,and water environment problems are identified,so as to provide technical support for carrying out water environment treatment and water ecological restoration in the watershed.
