| 摘 要： | 在流域非点源污染负荷估算中，采用了考虑降雨因素影响和污染物在迁移过程中损失的改进的输出系数法模型，并给出了降雨影响系数和流域损失系数的确定方法。改进后的模型应用于渭河流域总氮负荷量的估算，结果表明，改进后的输出系数模型机理更明确，模拟更符合实际，结果更接近监测值。同时分析了3类模型的特点及各自的适用范围。

| Abstract: | An improved export coefficient method for estimating polluting load of non-point source pollution is proposed. In the model the influences of rainfall and the reduction of pollutant in the process of transport are taken into accout and the methods for determining the rainfall coefficient and transport loss coefficient are given. The model is applied to estimate the toal nitrogen load in Weihe River watershed. It shows that the proposed model is feasible and the predicted result is approximately in accordance with the observated data. |

| Keywords: | non-point source pollution polluting load prediction improved export coefficient model total nitrogen |
