Research on Performance Evaluation of Sponge City Construction based on PSIR Model

Abstract

Sponge city construction refers to the construction of a city that can absorb water like a sponge and has good elasticity. The construction of sponge cities can store and save more water resources for cities, reducing phenomena such as rainwater infiltration, water scarcity, and water ecological environment damage. To scientifically and reasonably evaluate the performance of sponge city construction, this study summarizes the characteristics of sponge city construction models and the current development status of performance evaluation systems in China, and conducts analysis and research on the content of performance evaluation; Establish and screen a performance evaluation indicator system based on relevant theoretical foundations of performance evaluation; Construct a performance evaluation model for sponge city construction based on PSIR to address the design deficiencies of the existing performance evaluation system; And provide specific case studies, taking the sponge city construction in Bengbu City as the research object, to construct and clarify its specific application in project practice from the dimensions of water ecology, water environment, water security, water resources, water system, etc; Finally, a summary and outlook are provided for the entire study.
