介绍北京植物园园址的风特性模拟和新建大型热带植物温室表面风压分布的风洞实验结果。证明园址受樱桃沟谷底下洗气流影响产生局部强风区的机制，给出在不同风向下，大型温室顶部的平均风压和脉动风压均方根值分布的变化规律。
Wind tunnel simulation of the site of Beijing Botanical Garden and wind tunnel experiment results of wind pressure distribution on the surface of large-scale tropical greenhouse were introduced. It is proved that the mechanism of local strong wind area is affected by the scrubbing airflow at the bottom of the cherry valley, and the variation of rms value distribution of average wind pressure and fluctuating wind pressure at the top of large-scale greenhouse under different wind directions is given.
