摘　　要：随着我国高密度城市和航空交通的迅速发展,大量城市噪声敏感区域受到飞机噪声的影响。文章选择了20个典型的高密度城市样本和7个形态学参数,通过对飞机离港低空飞行阶段的噪声进行模拟,研究城市与飞行航迹之间的相对位置关系和城市形态特征对飞机噪声在室外空间分布的影响。结果表明:改变城市和航迹的角度、水平距离关系可以改善飞机噪声环境;城市形态与飞机噪声分布相关性显著;建筑立面降噪的有效距离为600m。With the rapid development of high-density cities and air traffic in China,many urban noise sensitive areas are affected by aircraft noise.In this paper,20 district samples and 7 morphological parameters of typical high-density city are selected to study the effects of the urban morphology characteristics and relative position relationship between the city and flight trajectories on the aircraft noise distribution in outdoor space,by simulating the noise of aircraft departure in its low-altitude flight stage.The results showed that:the angle and horizontal distance of trajectories to site have influence on aircraft noise environment;there is a significant correlation between urban morphology and aircraft noise distribution;the effective distance of building facade to reduce noise is 600m.
