高密度城市形态与风环境的关联性:大连案例研究
发布时间：2019-08-17 19:15
【摘要】：以大连一个16km~2范围的多高层混合高密度城市区域为例,通过CFD数值实验研究了城市规划指标对风环境的影响。将该区域中心的1km~2范围划分为200m×200m的方格网,获取了不同风速情境下共250组风速数据,利用SPSS对每个方格网内城市规划指标(建筑密度、容积率、绿地率)与风速比之间的定量关系进行回归分析,为定量分析城市规划指标和风环境之间的关系提供了一种思路,为创造良好城市环境提供了科学依据。
[Abstract]:Taking a multi-high-rise mixed high-density urban area in Dalian as an example, the influence of urban planning index on wind environment is studied by CFD numerical experiment. The 1km~2 range of the regional center is divided into 200m 脳 200m grid, and a total of 250 sets of wind speed data under different wind speed situations are obtained. The quantitative relationship between urban planning index (building density, volume rate, green land rate) and wind speed ratio in each grid is analyzed by SPSS, which provides a way of thinking for quantitative analysis of the relationship between urban planning index and wind environment, and provides a scientific basis for creating a good urban environment.
