Abstract: With the global climate changing and urbanization in China， the hydrological environment has been greatly affected. As a result， properly analyze the hydrological process and put forward the effective control measures has become the current research hot topic. According to basic data in a typical area， a model of urban hydrological process simulation is established using SWMM. Through the analysis of various rainfall frequencies， the change of urban drainage capacity， and peak time are studied， especially the low impact development (LID) strategies are proposed. The results of this research can provide theoretical basis and technical support for the analysis of urban hydrology and urbanization.
