摘　　要：本文以某城市综合体为研究对象,在风洞中开展了城市中心行人高度风环境影响试验研究。试验结果表明:在来流受阻挡区域风速明显下降,此时风速比小于1;受到峡谷风效应影响,风速出现明显放大,此时风速比大于1,最大的风速比达到了1.57。Wind tunnel tests of pedestrian level wind environments for a HOPSCA were conducted. The experimental results show that ： the wind speed reduced obviously when the inflow was obstructed, and then the wind speed ratio was less than 1; the wind speed was amplificated influenced by the gorge wind effect, and the wind speed ratio was large than 1, and the largest value reach to 1. 57.
