城市公共空间韧性:系统化思维下的概念框架、典型模式与运行机制OACHSSCD

Urban public space is a fundamental carrier of urban functions,and its re-silience depends on the systematic characteristics of the public space system.How-ever,the underlying mechanisms of urban public space resilience remain insuffi-ciently understood.This paper advocates a cognitive shift from element-based think-ing to system thinking.Through theoretical development and case-based analysis,it systematically elucidates the systematic nature of urban public space resilience and proposes an analytical framework integrating the dimensions of space,function,and governance.The findings indicates that enhancing public space resilience depends not only on the physical responsiveness of individual nodes but also on the structural sta-bility and functional structure at the system level.Based on this framework,the study identifies four representative features of urban public space resilience:sponge buffers,emergency shelters,microclimate regulation,and social restoration.It further examines four dimensions of resilience mechanism:spatial redundancy,risk buffering,spatial temporal transformation,and multi-actor collaboration.This study advances the theoretical understanding of urban public space resilience and provides scientific guidance and practical reference for resilient city planning,the development of disaster-response and adaptive reuse guidelines,and whole-life-cycle governance within the context of territorial spatial planning.
