摘　　要：城市雨洪韧性是雄安新区韧性城市建设的重要内容。在气候变化加剧和城市化快速推进的背景下,雄安新区建设面临更加复杂的水系统问题,需要以系统韧性的思维来构建适应未来内外环境变化的韧性雨洪系统。该研究提出系统韧性的概念,将复杂适应系统理论与韧性理论联系起来,作为分析城市雨洪韧性的理论框架,把城市雨洪系统视为由水系空间、自然生态、基础设施和社会经济等子系统所构成的复杂适应系统,提出增强系统韧性是应对水安全风险、提升雨洪管理整体效能的基本途径。在对雄安新区历史和未来暴雨洪涝灾害风险特征及其变化进行分析的基础上,从空间、生态、设施和社会等维度,探讨基于系统韧性的雄安新区适应性雨洪管理策略。在空间韧性维度,通过统筹流域防洪体系的建设管理,综合谋划区域性雨洪风险管控体系,实施低影响开发的城市空间策略,从流域-区域-城市等多层级构筑具有空间整体性的雨洪系统。在生态韧性维度,通过营造蓝绿交织的自然生态系统,提升水系网络的连通性,发挥生态系统服务的复合功能,构筑更具弹性、与水共生共融的生态雨洪系统。在设施韧性维度,通过增强防洪防涝设施系统的工程韧性,增强城市公共设施系统的承灾韧性,构筑具有强健性的基础设施系统。在社会韧性维度,通过建立多主体协同的组织管理机制、全过程管理的风险管控机制、学习与调适的社会适应机制,完善应对暴雨洪涝灾害的社会管理体系。Urban stormwater resilience is integral to constructing resilient cities in the Xiong’an New Area.The quest to build the Xiong’an New Area is confronted with increasingly complex water system problems in the circumstances of exacerbated climate change and rapid urbanization.From the perspective of system resilience,these difficulties require the institution of a robust stormwater man⁃agement system that can adapt to both internal and external environmental changes in the future.This paper proposes the concept of sys⁃tem resilience,linking the complex adaptive systems(CAS)theory with the resilience theory as a theoretical framework for analyzing ur⁃ban stormwater resilience.The urban stormwater management system is considered a CAS,comprising water space,natural ecology,in⁃frastructure,and social economy.The study postulates that enhancing system resilience could be a fundamental means of coping with water security risks and could help enhance the overall effectiveness of stormwater management.Furthermore,it discusses the historical instances and future threats of storm and flood disasters in the Xiong’an New Area.It then elucidates the proposed adaptive stormwater management strategy based on system resilience,explicating it through the dimensions of space,ecology,facilities,and society.A spa⁃tially integrated flood control system could be constructed at the river basin,region,and city levels to achieve spatial resilience.This ob⁃jective could be achieved by coordinating the construction and management of the flood control system in river basins,comprehensively planning the regional flood risk management system,and implementing the urban space strategy of low-impact development.Ecological resilience may be attained by constructing a more flexible and integrated ecological stormwater system.This objective would require the creation of a natural ecosystem of landscape and waters and better connectivity of the water system network,along with the holistic insti⁃tution of ecosystem services.Facilit
