Abstract: The construction of resilient cities represents a pivotal issue for China's pursuit of coordinated development and security. As urban development in China transitions from the 'incremental era' to the 'stock era', leveraging existing infrastructure to bolster urban resilience has become increasingly significant. Integrating the concept of 'dual-use' (normal and emergency) infrastructure into territorial spatial planning is crucial for supporting the establishment of a new security paradigm for urban and rural spaces. This paper delineates the evolution of resilient city theories, with a particular emphasis on the functional attributes, spatial configurations, and operational dynamics of 'dual-use' public infrastructure. In the Chinese context, the core challenge lies in the inadequate spatialtemporal coordination in the planning of 'dual-use' public infrastructure. Therefore, the paper proposes strengthening planning guidance and control across the entire process, spanning from pre-disaster warnings to emergency response and post-disaster recovery. It advocates for harmonizing the relationships between urban and rural areas, cities and communities, as well as space and facilities within territorial spatial planning to optimize the spatial arrangement of 'dual-use' public infrastructure. Furthermore, the paper underscores the importance of extensively utilizing novel technologies and methodologies to enhance assessment simulations and facilitate dynamic monitoring of urban resilience.
