| 摘 要： | 由农业产生的非点源污染是湖泊的主要污染源。为了研究太湖流域非点源污染负荷流失规律，选择了宜兴梅林小流域为研究对象，对降雨过程中径流流量及其污染物浓度随降雨—径流变化过程进行监测研究。采用统计和系统分析方法，建立径流量和非点源污染负荷输出量之间的数学统计模型，得出该流域非点源污染物流失规律，此方法可以推广到与该流域相似的其它地区的非点源污染研究中，应用于太湖流域水污染综合治理。

| Abstract: | Non-point source pollutants from ground precipitation-runoff are the main pollutant sources in lakes. Meilin watershed is chosen to study the loss law of non-point pollution charge of Taihu Basin. In the course of whole precipitation-runoff, the flux and the concentration of pollutants are monitored. The mathematical model of runoff flux and non-point source pollutants was founded by statistical and systematical assay method. The loss law of non-point pollution charge of this watershed was obtained in the end, and this may be applied to study on non-point source pollutant of other similar watershed in Taihu Basin. |

| Keywords: | Meilin watershed non-point source pollution precipitation-runoff loss law |
