Abstract:The sponge city construction has been questioned once offered. In order to promote the construction of sponge city in a healthy and orderly way, the relationship between urban storm waterlogging prevention and sponge city construction is analyzed. The causes of urban storm waterlogging are discussed; the structural measures and non-structural measures of urban waterlogging prevention are proposed. The monitoring and warning technology of urban storm waterlogging is discussed. The concept and connotation of sponge city are introduced, and the relationship between prevention of urban storm waterlogging and construction of sponge city is emphatically discussed. On the basis of construction the four subsystems of urban storm water management, such as source runoff control system, urban storm sewer system, excess rainfall runoff discharge system and urban water conservancy and flood control system, sponge city construction is expected to solve the problem of urban waterlogging.
