使用模拟降雨实验的方法初步得出新安江上游流域的降雨量和坡度与总氮总磷输出系数的关系，然后通过自然降雨条件下的径流小区实验对输出系数进行校准和验证，从而得到改进的输出系数模型。借助ArcGIS软件获取模型应用所需要的红壤茶园面积、降雨量和坡度，基于改进的输出系数模型来估算新安江上游流域红壤茶园总氮总磷的输出负荷。结果表明：新安江上游流域红壤茶园中总氮总磷的输出负荷分别为3618．72、521．17 kg/a。

By use of the method of simulating laboratory-rainfall, the paper got the relationship between rainfall, slope and export coefficients of TN and TP of in the upstream watershed of Xin'an river.It then calibrated and verified the export coefficient of TN and TP through the experiment of runoff plots under the condition of natural rainfall so as to obtain the model of improved export coefficient .With the help of Arc-GIS software , the paper got the area , rainfall and slope which was needed for model application .Based on the improvement model of export coefficient , it estimated export loads of TN in and TP in tea garden of red-soil of upstream watershed of Xinanjiang .The results showed that the pollution loads of TN and TP are 3618 .72 kg/a and 521 .17 kg/a respectively on the tea garden of red-soil in the upstream watershed of Xin'an river.
