| 摘 要： | SCS法是当前被广泛应用于非点源污染研究中降雨径流关系的一种方法，但是由于地理环境的差异，直接将该方法应用在上海郊区时误差较大，因此，笔者根据实测资料对模式的2个系数（前期损失量和径流曲线数）予以修正，并提出相应的模型。 |

| Abstract: | SCS hydrologic method has widely been used for both analyses of small urban watersheds and agricultural watersheds.However,there will be relative error when applying SCS hydrologic method due to differentiation of geographical conditions.Based on actual measurement data,modifications for two coefficients,i.e.preceding loss and runoff curve,were proposed with the corresponding model. |
| Keywords: | nonpoint source pollution surface runoff small watersheds Shanghai suburbs |
