In recent years，affected by global climate change，extreme rainfall has increased，and urban waterlogging is becoming a new type of natural disaster，seriously threatening urban development and the safety of people’s lives and property. However，China is a country with severe water scarcity，and there is a huge water shortage in cities. How to solve the problem of urban waterlogging and make good use of rainwater resources has become an urgent task. Therefore，it is necessary to change the traditional urban waterlogging control mode of “rapid drainage and terminal treatment”，take the concept of “natural infiltration，source control” from the perspective of water ecological restoration and water cycle regulation，and combine natural and artificial measures，underground construction and ground construction，and the green engineering，gray engineering and blue engineering，to establish the whole process management cvering source control，pipe network drainage，storm water absorption，and rainwater utilization.
