在全球气候变化与城市化进程加速的背景下，复合型灾害风险显著上升，传统防灾设施已难以应对极端情景下的应急需求。基于我国疫情防控与灾害防治经验提炼的“平急两用”理念，为破解城市空间功能刚性与应急需求弹性之间的矛盾提供了创新思路。本研究立足国土空间安全与韧性城市建设需求，聚焦城市地下空间“平急两用”协同规划的理论建构与实践路径。通过借鉴国内外相关建设经验，分析城市地下空间“平急两用”规划建设发展脉络与研究进展，以优化地下空间布局、提升城市地下空间利用效率、增强城市应对突发事件的能力为主要目的，提出了“平急两用”功能与地下空间体系的动态耦合机制，构建了城市地下空间“平急两用”建设的整体框架。从空间治理层面、规划设计层面和工作体系层面开展了“平急两用”理念下城市地下空间规划路径的探索，为地下空间建设与“平急两用”理念相耦合提供了理论支撑和方法路径，也为我国“平急两用”理念与其他城市相关专项规划传导耦合提供了可借鉴路径。

As global climate change and urbanization processes accelerate, the risks of compound disasters have significantly increased, rendering traditional disaster prevention facilities inadequate for meeting emergency demands under extreme scenarios. The “dual-use for normal and emergency situations" concept refined from China's pandemic prevention and disaster mitigation experiences provides innovative solutions to resolving the inherent conflict between the functional rigidity of urban spaces and the flexibility required for emergency responses. This study addresses the requirements for national space security and resilient city construction, focusing on theoretical framework development and practical implementation pathways for coordinated dual-use planning of urban underground spaces. By drawing on relevant construction experiences both in China and abroad, this study analyzes the development context and research progress of the dual-use planning and construction of urban underground spaces. It aims to optimize the layout of underground spaces, enhance their utilization efficiency, and strengthen cities' capabilities in responding to emergencies. A dynamic coupling mechanism between dual-use functionalities and underground space systems is proposed, and an integrated framework for dual-use urban underground space development is established. The research explores planning pathways for urban underground spaces under the dual-use concept from three dimensions: spatial governance, planning and design, and operational systems. This study provides theoretical support and methodological pathways for integrating underground space construction with the dual-use paradigm, and offers transferable pathways for integrating the dual-use concept with other specialized urban planning systems in China.
