Spatial Structure Planning and Optimization Strategy of Sponge City in Coastal Area

Yang, J. and Zheng, B., 2020. Spatial structure planning and optimization strategy of sponge city in coastal area. In: Yang, Y.; Mi, C.; Zhao, L., and Lam, S. (eds.), Global Topics and New Trends in Coastal Research: Port, Coastal and Ocean Engineering. Journal of Coastal Research, Special Issue No. 103, pp. 561–565. Coconut Creek (Florida), ISSN 0749-0208.Traditional planning methods for sponge city spatial structure in coastal areas do not consider enough natural environmental factors, resulting in low security of urban spatial structure and threatening people's living safety. Therefore, planning and optimization strategies for sponge city spatial structure in coastal areas are studied. Through detailed investigation of precipitation in coastal area and planning of urban traffic structure of sponge city, the sponge city can discharge flood. Combining the wind environment of coastal cities, wind galleries are designed to change the architectural space layout of sponge cities. To improve the living safety of sponge cities by acquiring target cities and formulating strategies for optimizing the spatial structure of offshore cities in coastal areas. The test results show that compared with the traditional planning method, the safety factor of urban space structure under this optimization strategy is higher, which provides guarantee for the development of sponge city.
