The problem of waterlogging in old city has become the focus of natural disaster research. Taking Fenghuang District of Nanchang City as an example, the MIKE FLOOD model was established to analyze the risk and causes of waterlogging. Based on the above results, the SWMM model was used to conduct the research on LID layout and optimization. Analytic hierarchy process was used to evaluate its comprehensive benefits, and the optimal cost-benefit scheme was finally obtained. According to the study, the rainfall return period is 5 years, there are 16 waterlogging points, and the risk level of waterlogging in some areas has reached level Ⅳ. It can be seen that the urban waterlogging prevention and control research is urgent. LID combination facilities have a good effect on alleviating waterlogging. The scheme of 22.5% rainwater garden +7.5% pervious pavement is the best. This conclusion can provide technical reference for the following low impact development and construction of sponge cities and the proportion selection of facilities.
