中文摘要:
      城市住区植物设计对区内风环境状况具有直接影响。本文以哈尔滨市3个高层住区户外环境为载体,运用CFD数值模拟技术,对不同植物布局及配置方式对典型风环境的影响进行研究,探讨提升住区风环境舒适性的植物设计形式。结果表明,穿流区、角流区、涡流区为高层住区风环境关键区域。树种配置方式中,小乔木+灌木对人行高度处风速削弱效果最好,大乔木+小乔木对风场的减弱范围最大;不同气流区域内植物布局方式应分别处理,穿流区采用垂直风向的行式布局、角流区采用平行于风向的列式布局、涡流区采用围合式布局对风环境改善效果最好。
英文摘要:
      The design of vegetation could significantly influence the wind environment in urban residential areas. This investigation analyzed the effect of different tree arrangement patterns and community configurations on the typical air flow fields,in order to explore the way improving the comfort level of residential area’s wind environment . The results of wind environment test and CFD digital simulations obtained from three residential areas of Harbin suggest that (1)the turbulent flow area, the angle flow area and the vortex flow area of dense-high-rise buildings are critical for design optimization.(2)Tree community configuration composed of small arbor and shrubs could effectively decrease the wind strength, while the community including big and small arbor could eliminate the range of wind fields. (3)Corresponding to exact air flow fields,vegetation design should consider different tree arrangement patterns to achieve best results. Row-typed tree arrangement pattern should be applied in a direction toward the air flow, line-typed tree arrangement pattern should be applied on the residential building corners,and enclosed tree arrangement pattern should implemented in the area where vortex wind dominates.
