Abstract: The construction of polder areas is crucial for ensuring flood control and waterlogging safety in low-lying areas of Shanghai. The frequent occurrence of catastrophic weather poses new challenges to flood control and waterlogging in polder areas. A detailed analysis was conducted on the current situation, problems, and development needs of the construction of polder areas in Shanghai. A series of countermeasures and suggestions were proposed to improve the layout of polder areas, clarify the engineering planning of polder areas, enhance the resilience of polder areas in flood control, improve the management level of polder areas, promote standardized management and intelligent construction of polder areas, in order to enhance the flood control and flood control capabilities of low-lying areas in Shanghai, ensure the safety of low-lying and flood prone areas, and strengthen the resilience of urban water safety.
