As a new urban development pattern, the construction of sponge cities has been deeply integrated into the new urbanization and water safety strategy. Nanning City, as one of the first batch of experimental sponge cities in China, has undertaken exploration and practice on sponge city planning, construction, and management. The sponge city master plan of Nanning City establishes an urban ecological spatial pattern in order to protect the security of the sponge base. The sponge city construction strategy has also proposed an overall construction strategy of a sponge city in line with urban development features. Through the systematic analysis and planning, a “23+10+202” pattern of sponge city construction has been formed. “23” represents 23 drainage basins, in which major sponge facilities such as storage facilities, waterfront buffer zones, wetland parks, ecological rainwater corridor and sponge parks are allocated. “10” represents 10 sponge functional zones, which provide important reference for the establishment of sponge city construction index system. “202” represents 202 management units, which decomposes the general objective and provides technical support not only for sponge city construction and management, but also for the implementation of general objectives in the regulatory plan as well.
