Coastal cities are facing a series of severe flood hazards led especially by rising of sea level and threats caused by severe heat island effects and extreme heat weaves. This article first summarizes the shortage of planning actions in coping with extreme climate of flood and extreme heat weave hazards faced by coastal cities in China. Then sorting out international experience of technologies and policies in mitigating and adapting to flood and heatwave hazards, and focuses on the main problems solved by applied technologies and the indicators involved (including time, costs, etc.). Through the identification of quantitative techniques, the spatial potential of the two major types of extreme climate disasters in downtown Shanghai and the priority application of mitigation and adaptation technologies are identified. Finally, from the technical and policy aspects, suggestions for mitigating and adapting to two types of extreme climate disasters in Shanghai's central urban areas are proposed.enheatwave and flood hazrdsmitigation and adaption techonologydowntown ShanghaiArticle1800-1820
