【摘要】 城市基础设施作为居民生活与公共服务的重要载体，其内部关联复杂，在洪涝灾害发生时既是灾害传播的媒介，也是抵御风险的关键。本研究提出一种融合复杂网络理论与城市韧性评估的创新框架，构建了涵盖避难、教育、商业等多维功能的应急服务设施网络模型。通过模拟不同重现期暴雨对城市网络的级联效应，量化关键系统的连通效率与恢复时间等韧性指标。研究发现：道路冗余度与设施可达性是影响恢复能力的关键因素；该模型能有效评估韧性动态特征，为高密度城区防洪规划提供决策支持。本研究为城市雨洪韧性研究提供了可扩展的量化分析方法，虽在社会经济维度存在一定局限，但建立了网络结构与功能恢复之间的量化关联，具有理论与实践价值。更多还原

【Abstract】 Urban infrastructure, as a vital carrier of residents’ lives and public services, is complexly interconnected. During floods, it serves as both a medium for disaster propagation and a key factor in mitigating risks. This study proposes an innovative framework integrating complex network theory and urban resilience assessment, constructing an emergency service facility network model encompassing multiple functions such as shelter,education,and commerce. By simulating the cascading effects of rainstorms with different return periods on the urban network, resilience indicators such as connectivity efficiency and recovery time of key systems are quantified. The study finds that road redundancy and facility accessibility are key factors influencing resilience. This model can effectively assess the dynamic characteristics of resilience, providing a decision-making basis for flood control planning in high-density urban areas. This research provides a scalable quantitative analysis method for urban stormwater resilience research. Although it has limitations in the socio-economic dimension,it establishes a quantitative correlation between network structure and functional recovery,possessing both theoretical and practical value.更多还原
