| 摘 要： | 以城市为单元模拟建立城市大气覆盖面模型，以小区为单元研究风环境与空气环境．获取城市建筑物空间坐标，利用二次曲面方程建立城市覆盖面模型，以新增建筑物为研究对象，对其空间位置进行插值分析，将其纳入城市小区建筑群构成新的小区环境，籍此对其进行风环境的实验分析，模拟建筑物的尺度、间距、空间组合与朝向定位等参数，辅助城市小区风环境规划与优化。

| Abstract: | The spatial layer model of an urban area was built,the wind envoirnment and air envoirnment of an urban quarter were investigated. The three dimensional coordinates of buildings was obtained,the spatial layer model of urban area was built,that with the two order curve equation. Spatial coordinates of a new building was interpolated,the new building was encased as a part of building group,and the wind envoirnment of the new quarter in the urban area was analyzed,the dimension,distance between two buildings,orientation were simulated. The planning and optimization of wind envoirnment of an urban quarter were supported. 5figs.,2tabs.,10refs. |
