Under the influence of global climate change and rapid urbanization, urban flood disaster becomes more and more serious. Urban flood disaster risk assessment and risk response strategy have become a hot issue in sponge city research. This study introduce the basic concept of sponge urban construction risk and the basic theory, using the grounded theory to determine the sponge risk factors for urban construction, building based on system dynamics dynamic evolution model of the urban construction risk, sponge city construction in Jiangxi province as the research object, the application of Vensim PLE software carries on the simulation results. This paper analyzes the dynamic development situation and key risk factors of each sub-risk system in the whole life cycle, and discusses what countermeasures should be taken to reduce the risk of sponge city construction.
