摘　　要：本文旨在明晰城市综合防灾规划领域中韧性城市的界定与概念内涵,基于前期对防灾韧性城市发展脉络的综述性研究,推演出逻辑自洽的防灾韧性城市(Disaster Resilient City)的本质内涵、分形结构与特征向量。主要结论:防灾韧性城市的本质内涵是以人为本的服务供给、动态演进的自适应过程、跨尺度多系统的关联协同;其分形结构统一于由“节点—边”联结的物质环境系统与社会网络系统交织的高阶复杂城市网络结构;基于“结构—功能”模型推导出具有独立自由度的四维特征向量,即鲁棒性、冗余性、多样性和治理能力。研究有利于明确防灾韧性城市的概念,构建广泛共识与深入探讨的基础,形成城市安全与防灾减灾领域韧性城市的研究边界,推动综合防灾规划理论的演进。This paper aims to clarify the definition and conceptual implications of resilient cities within the domain of comprehensive urban disaster prevention planning.After a review of the development trajectory of disaster resilient cities,it deduces a logically coherent essence,fractal structure,and characteristic vectors that define such cities,which can be summarized as follows.The essence of disaster resilient cities lies in people-oriented service provisions,a dynamically adaptive evolutionary process,and cross-scale interrelation and coordination among multiple systems.Their fractal structure is unified in a high-order complex urban network structure generated by the interweaving between the physical environment system and the social network system that are connected by“node-edge”links.Based on the“structure-function”model,it identifies fourdimensional characteristic vectors:robustness,redundancy,diversity,and governance capability,each with a degree of freedom.The paper is conducive to clarifying the concept of disaster resilient cities,building a foundation for broad consensus and in-depth discussion,and forming the research boundaries in the field of urban safety and disaster prevention and mitigation,so as to promote the evolution of comprehensive disaster prevention planning theory.
