Sponge city technology is widely used as the critical approaches in natural rainwater management and it is one of the best techniques to adapt climate change events in modern cities. In the paper, we firstly reviewed background information of sponge city construction and the development, key technologies, and economic benefit analysis of stormwater management in foreign countries. Then, we analyzed the technology gap between China and developed countries in two aspects (planning design method and Low Impact Development (LID) project design). Then, we pointed out the main obstacles in sponge city technology transfer and proposed to improve the basic data sharing system and strengthen the economic return system. On the basis of sponge city planning theory and sponge city technologies, taking Shenzhen as an example, we analyzed the ideas and plans of sponge city construction in rainy areas and completed the assessment of current climate technology demands in Chinese sponge city. The study provides the basis for the improvements in sponge city construction and adaptation to climate change.展开更多

Urban adaptation is aimed at the sensitivity level of risks and specific impacts of cities under the impact of climate change, and to develop policies and investment programs to reduce the vulnerability of cities to climate change risk. Urban adaptive action provides the basis and direction for the construction of urban resilience and sustainable development. Identifying the demand of adaption technologies, promoting the practical implementation of international technology transfer and reducing domestic emissions have important significance for the global response to climate change and improvement of the ability of urban adaptation. In this paper, through in-depth analysis on the concept and connotation of climate change, climate disasters and urban adaptation to climate change, the evaluation framework and steps of urban adaptation to climate change technology are determined, and six priority application technologies which can maximize the overall efficiency of sustainable development, improve the ability to adapt to climate change and at the same time reduce the cost at the greatest extent are identified.展开更多
