| 摘要: |
| 严寒地区长达6个月以上的冬季使城市面临更加独特且多元的气候问题，如低温、冷风、冰雪等，这种复杂气候对城市安全的影响成为严寒地区城市设计亟待解决的问题。通过系统性文献综述，梳理既有研究针对城市设计要素与气候韧性关系达成的共识性认知，得到气候韧性视角下城市设计不同维度构成要素的属性特征。以此为基础，针对严寒地区独特多元的气候问题，提出包含调蓄旱涝的生态安全格局、多样连通的生物安全格局、多中心紧凑型城市形态格局、改善雾霾的多层级通风廊道格局、改善冬季光环境舒适性的公共空间体系等内容的气候韧性导向的城市设计框架，并结合住建部城市设计试点项目长春市总体城市设计进行实践应用。以期为中国严寒地区开展应对气候灾害的韧性城市设计提供方法框架和技术指引。 |

| Abstract: |
| Cities in severe cold regions are faced with unique and diversified climate problems, such as low temperature, cold wind, ice and snow. The impact of such a complex climate on urban safety has become an urgent problem to be solved. Through systematic literature review, this research sorts out the consensus on the relationship between urban design elements and climate resilience, and summarizes the key features of urban formations that affect climate resilience. It proposes climate resilience oriented urban design framework for cities in severe cold regions to solve unique and diversified climate problems. The framework is comprised of an ecological safe system (for regulation of drought and flood), bio-safety system (for diversity and connection), multi-center urban morphology system (for redundancy and compact), multi-scale ventilation corridor system (mitigation of fog and haze), and public space system (for light environment comfort in Winter). The framework is also applied in general urban designs of Changchun, a pilot project of the Ministry of Housing and Urban-Rural Development of China, with an aim to provide methodology framework and technical guidelines for urban design practice in severe cold regions of China. |
