为了改善城市通风环境,文章以空气流动理论机理、夏季城市的主要风源、影响城市通风的主要规划因素为理论基础,研究提出城市通风廊道的规划方法,包括宽度、走向、开敞空间、相邻界面、建筑5个方面的规划控制指标。并以《广州市白云新城北部延伸区控制性详细规划》为例,分析介绍了该案例中7条通风廊道的规划构建及其控制方法与指标要求。

In order to improve the city ventilation, based on the theory of ventilation, the analysis of main wind sources in summer and the main factors affecting urban ventilation, this paper describes a new method of ventilation corridor planning, and establishes a control indicator system from five aspects： Width, Direction, Open Space, Adjacent Interface, Building. Taking the case of the Regulatory Planning of Baiyun New Town North, Guangzhou as an example, this paper analyses the planning, control method and indices of the seven ventilation corridors.
