Abstract: As urban populations and activities continue to concentrate at high density, cities face increasingly severe challenges from coupled risks. Urban risk has entered a “3.0 stage,” in which normalized long-term pressures coexist and interact with sudden disturbances, making multi-risk coupling a major theme in urban resilience research. Against the challenges of future urban development, this paper reviews the characteristics and scenarios of multi-risk coupling, its spatial effects and mechanisms, and relevant planning practices. It then identifies key theoretical dimensions of resilience under coupled risks, including the interaction of ecological, social, engineering, and economic resilience; long and short resilience cycles; resilience thresholds; and cross-scale transmission. On this basis, the paper develops a framework for resilient territorial spatial planning and specifies resilience priorities for master, detailed, and specialized plans. Finally, it outlines future technical directions for plan preparation, including multisource information acquisition and processing, risk overlay and coupling assessment, scenario deduction and simulation, and AI-assisted planning and implementation monitoring. The study provides a theoretical reference and methodological guidance for resilient-city planning and construction in the new era.
