城市安全、气候风险与气候适应型城市建设

Urban safety,climate risk and climate-adapted urban construction

我国是遭受极端气候事件和气候变化不利影响较严重的国家。随着城市化进程持续快速推进,气候变化的不利影响与自然灾害叠加,已成为制约城市可持续发展的重大问题。积极推动气候适应型城市建设,是推动我国城镇化高质量发展的必然要求。国外韧性城市建设与国内海绵城市建设试点为开展气候适应型城市建设提供了重要参考。气候适应型城市建设的重点在于:找准定位,系统建设;明确目标,突出重点;规划先行,重在增量;分类实施,综合应对;分区适应,均衡发展;协同推进,持续改善。同时,要完善多中心、多主体参与的城市适应治理机制;结合区域差异,制定本地化、个性化适应措施;协同应对气候风险,持续提升城市安全水平。

China is a country with severe adverse impacts from extreme weather events and climate change.As the urbanization process continues to advance rapidly,the adverse effects of climate change and natural disasters have become a major problem that constrains the sustainable development of cities. Actively promoting the construction of climate-adapted cities is an inevitable requirement for promoting the high-quality development of urbanization in China. The construction of foreign tough cities and the pilot construction of domestic sponge cities provide an important reference for the development of climate-adapted cities. The key points of climateadapted city construction are: to find correct positioning,to clarify goals,to highlight key points;to plan ahead,to focus on incremental;to implement classification,to comprehensively respond;to adapt to partitions,to achieve balanced development;to promote synergies and to continuously improve. At the same time,it is necessary to improve the multi-center,multi-subject participation in urban adaptation governance mechanisms;in combination with regional differences,develop localized and personalized adaptation measures;coordinate climate responses and continuously improve urban safety.
