摘　　要：雨洪管理模型(SWMM)是广泛应用的城市雨水模拟和分析软件,子汇水区是SWMM模型中基本计算单元.通过分析总结SWMM模型的降雨径流水文概念模型、子汇水区产流模型和汇流模型,结合模型原理,提出参数赋值建议,并针对子汇水区宽度初步赋值方法存在的问题,提出以地表漫流长度作为计算子汇水区宽度的基础方法,根据子汇水区最大集水距离加权计算地表漫流长度,并对加权计算的结果进行了对比.Storm Water Management Model(SWMM)is a widely used urban rainwater simulation and analysis software,the sub-catchment is the basic calculation unit in the SWMM model.Through the analysis of the rainfall runoff hydrological conceptual model,runoff yield and concentration mathematical model for SWMM sub-catchment,some suggestions on parameter assignment are put forward the application.In order to solve the problem of sub-catchment width value assignment,this paper proposes to take the length of the overland flow path as the basic method to calculate the width of the sub-catchment area,and to calculate the length by weighting the length of sub-catchment concentration.

关 键 词：雨洪管理模型(SWMM) 子汇水区 产汇流模型 地表漫流长度
