Abstract:The construction of sponge city is an important measure for the national ecological civilization construction. In the past ten years of sponge city construction and development, it has been relatively mature in planning and design methods, system theory research and model software applications. The widespread application of modern software technology in special planning of sponge city strongly supports the professional and scientific degree of planning preparation. Due to the lack of standardization, the different methods and processes are used to prepare the planning, which makes many uncertainties in the process of planning preparation, and reduces the working efficiency. The quality and feasibility of the final preparation scheme also show great differences. In order to improve the quality of planning results and the work efficiency of planning and design personnel, the connotation and technical path of planning preparation standardization for sponge city under the new situation are studied, which provides the new ideas for the technological change and management of planners and designers.
