Taking sponge city planning of Qingzhen City as an example, this study formulated three-level control strategies according to the development status of different regions and urban function positioning. Combined with the protection and restoration requirements of the construction of a sponge city, it establishes a three-level sponge city zoning control index system of "four-function large zoning +33 management and control units + eight types of land sponge planning", decomposes the low-impact development control objectives, and finally achieves the total runoff control objectives. The research will provide theoretical reference and technical support for sponge city construction in karst area.
