在快速城镇化与极端气候加剧环境变化的背景下，城市面临越来越多的风险与挑战，安全韧性成为城市规划、建设和治理的焦点。安全韧性城市规划不仅仅是围绕防灾减灾的专项规划，而是城市规划与设计的安全韧性整体升维。本文基于我国城市存量发展的问题与需求，在“风险源 ‒ 承灾体 ‒ 减灾力”城市安全框架的基础上，提出安全韧性城市规划与设计的理论原则与逻辑框架，构建了“系统 ‒ 时间 ‒ 空间”三维思考结构，并提出“技术方法‒ 规划内容 ‒ 政策法规”三重实践路径。文章系统解析了由基础理论向应用实践转化的技术路线，提出安全韧性城市规划与设计应以“因险制宜、形数共构”为指导思想、“适度承压、迅速复能”为战略目标、综合“精准适配、以数赋形”的方法体系与技术手段，以期为安全韧性城市规划与设计建立底层逻辑，进而为城市安全治理提供源头策略。

In the context of rapid urbanization and environmental changes exacerbated by extreme climates, cities are increasingly confronted with risks and challenges, making safety and resilience the focus of urban planning, construction, and governance. Safe and resilient urban planning is not only a specialized plan centered on disaster prevention and mitigation, but also an overall enhancement of safety and resilience in urban planning and design. Facing the problems of and demand for stock development of cities in China and based on a "risk source ‒ exposure ‒ mitigation" urban safety framework, this study proposes theoretical principles and a logical framework of safe and resilient urban planning and design. It constructs a three-dimensional thinking structure encompassing "system ‒ time ‒ space" and proposes a three-pronged practical pathway consisting of "technical methods, planning content, as well as policies and regulations." Furthermore, the study expounds on the technical route for the transformation from basic theory to practical application, advocating that safe and resilient urban planning and design should be guided by the principle of "adapting to risks and integrating form with data." The strategic objective is set as "tolerating moderate pressure and achieving rapid recovery," accompanied by a comprehensive methodology and technical toolkit that emphasizes precise adaptation and data-driven shaping. It is hoped to establish an underlying logic for safe and resilient urban planning and provide fundamental strategies for urban safety governance.
