At present, the accelerating urbanization process has gradually led to a series of urban ecological problems, such as resource shortage, pollution intensification, and climate deterioration. It has also brought great disturbance, impact, and pressure to urban infrastructure. Therefore, how to enhance the adaptability of cities to cope with the above-mentioned ecological problems through the planning and designing urban infrastructure has become an important issue in promoting urban sustainable development. Based on this, this article, based on the concept of resilience expounds on the connotation, hierarchy, and principles of composite infrastructure from three levels: resource production and supply, residents’ life reconstruction and natural ecological regulation by clarifying the systematic relationship between resilient cities and infrastructure. At the same time, with the help of the analysis of the Eco-Corridor of Ningbo’s East Town planning and design, the paper puts forward the composite infrastructure planning and design strategy of “production, life and ecology”, which provides a theoretical and practical reference for China’s sustainable urban development.
