| 改善通风的城市形态因素可以分为建筑和道路2个方面。建筑形态的通风评价主要采取综合迎风面积密度方法，将城市建筑环境转化为具有数值属性的栅格，从而提取城市建成区的通风廊道，但是该方法忽略了城市重要的通风路径——城市街道。以街道的朝向为主要评价对象，挖掘线状要素城市道路的通风廊道，作为建筑形态通风廊道划分方法的补充。根据通风潜力随夹角的变化规律，利用地理信息系统(GIS)的空间分析技术进行街道的通风潜力评价，在综合迎风面积密度密集的区域，存在通风潜力较高的城市街道 |

| Abstract: |
| The urban morphology can be divided into two aspects: buildings and streets. The building ventilation method is based on building front area density, and the building environment is divided into grids with numerical attributes so as to extract ventilation path, but this method ignores the ventilation path of urban street. The direction of the street is the main evaluation index to extract the ventilation path, which is the supplement of the building method. According to the angle of street, the spatial analysis technology of Geographic Information System(GIS) was used to evaluate the potential of street ventilation. In the grids of high front area density, there are some potential ventilation urban streets. |
