摘　　要：理解风险扰动过程中城市空间结构的演化机理和影响机制,对韧性城市规划建设具有重要的理论与实践意义。本文立足于流网络与物质空间网络的耦合关系,解构“风险扰动—空间结构—居民生活”关联逻辑,剖析风险扰动作用下城市空间结构与居民生活之间的关系;以要素流动为介质,将风险扰动、空间结构、居民生活纳入统一的分析框架,从风险扰动对城市空间结构的作用机制、城市空间结构的动态演化、城市空间结构变化和空间应急响应四个层面,建立起风险扰动视角下城市空间结构的韧性机理研究理论框架;结合典型风险扰动场景,从空间网络构建、城市韧性测度、关键要素识别和智慧韧性治理四个方面提出韧性机理研究的实证方法。本文可为城市韧性机理和可视化优化调控研究提供新的视角。Understanding the mechanism of risk disturbances and its dynamic processes on urban spatial structure is of great practical and theoretical significance for resilient urban planning and construction.This paper analyzes the relationship of urban spatial structure and residents’lives under the effect of risk disturbances based on the coupling relationship between flow network and spatial network.We integrate risk disturbance,spatial structure,and daily life into a unified analytical framework by using elements’flow as the medium.From the perspective of risk disturbance,we develop a theoretical framework for studying the resilience mechanism of urban spatial structure at four levels:the mechanism by which risk disturbance affects urban spatial structure,the dynamics of urban spatial structure,the change of urban spatial structure,and space emergency response.An empirical method to investigate urban spatial structure resilience mechanisms is proposed by combining typical risk disturbance scenarios with four components:construction of spatial networks,urban resilience measurement,identification of key elements,and smart resilience governance,providing a new perspective for researches on urban resilience mechanism and optimal spatial regulation.
