摘　　要：全面梳理了国内外内涝风险图发展历程,系统分析了我国城市内涝风险图的核心组成、编制思路,重点探讨了我国城市内涝风险图编制的若干关键问题和技术需求,并结合现阶段我国城市内涝治理工作要求,对城市内涝风险图研究和工程实践进行了展望。指出城市内涝风险评估应从致灾因子危险性、孕灾环境暴露性和承灾体脆弱性3方面进行,采用指标体系法和情景模拟法相结合的方法编制城市内涝风险图。城市内涝风险图应对综合风险和潜在损失等多种信息进行全面、精准的表达,其编制是一项极其复杂的系统工程。未来需重点关注不同于流域尺度的城市下垫面产汇流特征及内涝形成演进机制,从高质量基础数据、高效模型和标准规范等方面进一步研究。This paper comprehensively combed the development process of urban waterlogging risk maps in various countries,systematically analyzed the core components and compilation ideas of the urban waterlogging risk map,and focused on exploring several key issues and technical requirements for the compilation of urban waterlogging risk maps in China.Combined with the current requirements of urban waterlogging control in China,the development of urban waterlogging risk map research and engineering practice was prospected.It was pointed out that the risk assessment of urban waterlogging should be carried out from three aspects including risk of disaster causing factors,exposure to breeding disaster environment,and vulnerability of disaster carriers,and a combination of scenario simulation method and indicator system method should be used.The urban waterlogging risk map should express the comprehensive and accurate information such as comprehensive risk and potential loss,and the compilation is an extremely complex system engineering.In the future,it is necessary to focus on the characteristics of urban underlying surface runoff and the evolution mechanism of waterlogging at different watershed scales,and further research should be conducted from high-quality basic data,efficient models,and standard specifications.
