基于调查和数值模拟的长春市街区风屏障空间评定方法

摘要

In the process of urban development in China,most of the cities experienced different degrees of rapid ex-pansion of the city scale,at the same time they had an impact on the microclimate of the city.Two-thirds of China's land are cold areas. In these areas,improving the comfort of the outdoor environment in winter and creating wind barriers space in the neighborhood is a prerequisite for enhancing the quality of life of residents.How to judge and i-dentify the existing wind barrier space in city blocks and optimize their organic components is the key point of this paper.Using the research method combining the subjective and objective evaluation of questionnaire and numerical simulation to judge the existing typical wind barrier space in Changchun,to provide a reference method for impro-ving the winter comfort level in the northern winter city of our country.%随着城市规模的快速扩张,城市微气候环境日益恶化,我国有三分之二城市位于寒冷地区,提升寒地城市冬季室外环境舒适度、打造街区风屏障空间对提高居民生活品质具有重要作用.因此,如何判定识别城市街区中现有风屏障空间、优化其有机构成要素已成为城市设计领域中的重要课题.本文对此采用问卷调查与数值模拟相结合的主客观评价方法筛选评定出了长春市现有典型风屏障空间,该方法为我国寒地城市改善冬季舒适度提供参考依据.
