摘要： 为了合理利用紫色土流域的水土资源，对紫色土坡地的降雨产生的径流量进行模拟，为农田非点源污染物输出模拟提供科学依据。此次试验地位于四川盆地中部，独特的紫色土资源与亚热带气候的最佳组合成为四川农业的主体区域，运用SCS模型计算试验小区在2005年的三场降雨产生的径流量，通过校正Ia和CN参数，小区计算值和实测值的误差分别为6.46%，10.22%和8.40%，得到了可信度较高的结果，同时说明了SCS模型在估算紫色土流域径流量的可行性。

Abstract: In attempt to make use of water and soil resource in the watershed of purple soil reasonably, we simulated the runoff from rainfall in the slope land of purple soil, providing scientific basis for simulating the no-point source pollution from farmland. The experimental plot situated at the middle of Sichuan Basin, the peculiar resource of purple soil and subtropic climate make it become the principal part of Sichuan agriculture.This paper，using Soil Conservation Service Curve Number method（SCS），calculated the volume of rainfall runoff in 2005, through calibrating the parameter Ia and parameter CN. it can received the suitable range of parameter, and the arverage error are respectively 6.46%,10.22% and 8.40%. It also show the feasibility that the application of SCS model to estimate the volume of rainfall runoff in sloping field of purple soil
