| 中文摘要: |
| 分析了城市地表雨水产流特性，讨论了城市地表雨水产流的计算方法，通过比较分析得出：对城市不透水区，降雨损失主要以初损中的洼蓄为主，若精度要求较高，宜采用蓄满产流中的指数分布计算方法或变径流系数法；若精度要求一般，可采用SCS曲线法或综合径流系数法．对于城市透水区域，降雨损失主要以下渗为主，若精度要求较高，宜采用结合下渗曲线公式的下渗曲线法；若精度要求一般，可采用指标法。 |

| The property and the calculating method of the urban surface runoff yield were discussed and analyzed in this paper.By the analyzing theory,a conclusion is obtained that the index distributed computing technology of the runoff volume method or the vary runoff coefficient law can be applied in an urban waterproof district if the precision is expected relatively much,otherwise SCS curve law or comprehensive surface flow coefficient law can be adopted if the precision requires generally;SCS curve law or comprehensive surface runoff coefficient law,and the infiltrating curve method united with the infiltrating equation can be applied if the precision is expected relatively much because the infiltrating losses are oozed mainly to the urban water area,otherwise the index method can can be adopted if the precision requires generally. |
