郑州市居住区建筑布局对风环境的影响

Influence of Building Layout in Residential Region of Zhengzhou on Wind Environment

快速的城市化进程中,高密度城市中的不同建筑布局带来的风环境改变的问题日益受到关注。研究选取郑州市区不同方位上离市中心不同距离、不同布局的"宝景花园""东郡香域巴黎""帝湖花园"和"非常国际"4个住宅小区,并对其风速进行测量记录,研究小区的建筑布局对风环境的影响。结果显示:春季静风状态下,距离市中心由远及近的小区风速有减小趋势;不同布局特点的建筑风速大小有差异,呈现为点状式>行列式>围合式。

In the rapid urbanization process, wind environment change problem brought by different architecture layouts in high-density city is concerned increasingly. Four residential districts with different layout characteristics at different directions of Zhengzhou City were selected, and they were ＂Baojing Garden＂, ＂Dongjun Xiangyu Pairs＂, ＂Dihu Garden＂ and ＂Feichang International Community＂. The wind speed was measured and recorded, to find out the influence of different architecture layouts in the residential district on wind environment. Results disployed that under the condition of spring static wind, the wind speed had a decreasing trend in the residential district with the distance from far to near urban district. For different building layouts, wind speed was different, which showed as interspersed 〉 linear 〉 enclosed.
