URBAN SPATIAL RESILIENCE TRANSMISSION IN FLOOD MANAGEMENT:MULTI-SCALE NESTED STRUCTURES AND INTERACTION RELATIONSHIPS
Floods pose a significant challenge to the high-quality development of urban areas.The integration of flood resilience construction into the territorial planning and governance system,the alignment of urban spatial layout with the logic and order of flood resilience,and the differentiation of disaster management pathways according to various spatial scales are pressing needs for cities to sustain their growth and ensure a safe living environment amidst the changing climatic conditions.This paper establishes a multi-scale theoretical transmission framework that links urban space with flood resilience.Taking Xiamen Island as an example,it elucidates fundamental unit types,multi-scale nested structures,and cross-scale interaction relationships associated with urban flood resilience.Accordingly,it proposes a multi-scale transmission optimization strategy characterized by"type segmentation,structural rationalization,and relationship reshaping".The objective is to enhance the depth and breadth of research into the relationship between urban spatial layout and flood resilience,as well as hierarchical studies.It may provide a scientific basis for implementing"multi-plan integration",planning transmission,and facilitating cities'dynamic adaptation to floods.
