Abstract: Based on the development history of sponge city construction system in China and abroad, this paper explores the similarities and differences and development experiences of sponge cities in various countries. Taking the rain garden as the research object, this paper analyzes the effect of its structural composition, hydraulic characteristics, and plant configuration on runoff pollution; these can be used to provide a theoretical reference for the construction of sponge cities in China. Finally, potential problems and risks in the construction of the sponge city were presented, and suggestions and prospects for the construction of a sponge city such as mosquito breeding and plugging are presented, and suggestions and prospects for the construction of a sponge city in China are proposed. It is important to learn from the development history of foreign stormwater management systems and realize the "Sinification" of stormwater management in practice by:adapting to local conditions, focusing on regional differences, strengthening field trials, and exploring the control mechanism of sponge cities on runoff pollution. Meanwhile, the potential risks and problems related to plugging and mosquito breeding in sponge city construction should also be taken seriously.

Key words: sponge city, development history, rain garden, runoff pollution control, problems and risks
