摘　　要：为了对赣江流域非点源污染排放负荷进行宏观评估,在已有研究的基础上,建立了改进的输出系数模型。通过分析赣江下游地区土地利用、农业人口和畜禽养殖等基础资料,确定了赣江下游各污染源产生的污染负荷量,并通过峡江和外洲两个水文控制站的实测数据,确定了赣江下游流域污染物迁移过程中的降雨影响系数和流域损失系数。用建立的模型计算了赣江下游非点源N、P污染负荷模拟值,并与实测污染负荷量进行了比较。结果表明,模型模拟精度较好,适合用于区域非点源污染负荷估算。In order to make a macroscopic evaluation on non - point source pollution load of lower Ganjiang River, on the basis of the previous study, an improved output coefficient model is established. By collecting the data of land utilization, agriculturag population and livestock production and other basic materials in various pollution sources in the downstream area is determined. the downstream areas of Ganjiang River, the pollution load from Through the measured data of Xiajiang and Waizhou hydrological control stations on the Ganjiang River, the influential coefficient of the rainfall and basin loss coefficient in pollutant migration in the downstream area are determined. By the established model, N, P pollutant loads of non - point source pollution in the downstream area are calculated, and compared with the measured pollution load. The comparison results show that the model simulation accuracy is better and the model is suitable for regional non - point source pollution load estimation.
