摘要
文章选取武汉汉口的大智路片区为研究对象,以实地观测和对比的方式研究夏季白天的老城区气候特征,并以此作为Phoenics软件模拟的边界条件,模拟和分析了三条不同高宽比和走向的街道峡谷的风、热环境差异,并根据模拟结果对其进行优化策略研究。研究显示,高宽比与走向均对街道的风、热环境产生影响,而建筑形态的优化、部分周边建筑的拆除,则能对风、热环境起到较好改善作用,该研究将为夏热冬冷地区的城市可持续更新和微气候改善提供理论支持。
In this paper,Dazhi Road area of Hankou,Wuhan was selected as the research object to study the climate characteristics of the old urban area in summer daytime field observation and comparison,which were used as the boundary conditions simulated by Phoenics software.The wind and thermal environment differences of three street canyons with different aspect ratio and trend are simulated and analyzed,and the optimization strategy was studied according to the simulation results.The study shows that both aspect ratio and trend have an impact on the wind and thermal environment of the streets,while the optimization of building form and the demolition of some surrounding buildings can improve the wind and thermal environment,which will provide theoretical support for the sustainable urban renewal microclimate improvement in the hot summer and cold winter areas.
