Contemporary cities and territories are facing significant challenges of natural disasters due to climate change impacts. Urbanized deltas represent some of the most vibrant and diverse ecosystems. However, its unique conditions of low altitude, land subsidence, and rapid urbanization make it more vulnerable when being subject to risks such as tide, storm surge, rainstorm, etc. caused by climate change. Firstly, this article reviews recent studies on theories and practice of city and regional resilience, and analyzes the spatial implications of it. Secondly, it analyzes the geographical characteristics, regional urban system, economic and social correlation, multi-scaled life cycle, and so on of China Yangtze River Delta cities. On the basis of this, it puts forward several problems in resilience planning practices faced by the Delta area. Thirdly, it proposes that general resilience development objective of delta cities is to promote their ability to deal with climate change. Some strategies including basic principles and steps of resilience planning such as plurality and diversified infrastructure, redundancy and multi-scaled networking, self-organized and self-renewal region / neighborhood / architecture / landscape layout are put forwarded. Lastly, the key thoughts in the China Yangtze River Delta Cities resilience planning are systematically exploring uncertainties related to future trends and disruptive events, thinking through the impacts of each sector on other sectors and the area as a whole, and making joint visions and identifying strategic projects not only among public actors but also with private and civic actors.
