摘要
Abstract
To implement the requirements of resilient city development and promote the transformation of urban flood management from passive end-of-pipe treatment to systematic source control,Guangzhou City,Guangdong Province,took the national lead in 2021 by introducing a flood safety assessment system during the urban planning stage.Since its implementation,significant results have been achieved in areas such as spatial control of river networks,implementation of flood control and drainage facilities,realization of sponge storage facilities,and waterlogging management.From 2022 to 2024,through flood safety assessments in 481 regulatory detailed plans,1001 km of planned river and lake control lines and 18.54 million m3 of sponge storage facilities were implemented.Using Guangzhou as an example,the development process and effectiveness of the flood safety assessment system were summarized,and the assessment contents and requirements were analyzed.The study shows that flood safety assessment is a key innovative mechanism to address the current urban flood dilemma:first,shifting the focus of urban flood management from post-event response to pre-event control,strengthening guidance and supervision during the planning stage,and controlling flood safety from the source;second,improving urban flood resilience through integrated measures and three-dimensional defense.Based on Guangzhou's exploratory practice,it is proposed that flood safety should be regarded as a rigid constraint in urban development,and that urban flood management should shift from adversarial defense to resilience governance,with strengthened application of flood risk analysis techniques and results in urban planning.This provides insights for resilient city development and serves as a reference for other cities in China.关键词
