| 摘 要： | 雨水产汇流过程受地表状况、降雨强度、降雨历时、土壤前期含水量等多因素的影响，试验采用SBS(屋面防水材料)、不透水地砖(人行道铺设材料)及草地三种不同下垫面材料，进行了多场模拟降雨试验。试验结果表明，透水性差的下垫面（SBS、不透水地砖），主要影响因素是雨强、历时，历时越长，雨强越大，径流系数越大。透水性较好的下垫面（草地），土壤前期含水量是影响产流量的主要因素，试验同时表明草地覆盖率大于80%，径流系数显著减小。经对试验数据进行回归分析，建立了一定条件下降雨历时?径流系数，雨强?径流系数，流量?径流系数之间的函数模型。研究成果对城市雨水资源利用具有重要参考价值和实际指导意义。 |

| Abstract: | The process of runoff-producing and flow concentration is affected by surface conditions, rainfall intensity, duration, soil moisture and other factors, Using three different underlying surface materials of SBS (roofing materials), impervious tiles (sidewalk paving materials) and grass, rainfall experiments are conducted. The results show that, for the poor permeability of the underlying surface (SBS, impervious tiles), main factors are the rainfall intensity, duration,and duration is longer, rainfall intensity is greater, the runoff coefficient is greater. For the better permeable land surface (grass), pre-soil moisture content is the main factors affecting. Experiment also shows that the grass cover is greater than 80%, runoff coefficient is reduced significantly. The mathematical relationships of rainfall duration and Runoff coefficient, rainfall intensity and runoff coefficient, flow and runoff coefficient are made. The results have important reference value and practical significance for urban water resources utilization. |
| Keywords: | uniform rainfall city's underlying surface runoff coefficient artificial rainfall runoff-producing |
