摘要
城市噪声污染是城市环境问题的四大公害之一,其中交通噪声已成为环境噪声污染的最主要来源,其危害的严重性已经引起了一系列的人居环境问题。为了了解城市噪声垂直空间上的分布规律,本文选取了佛山市内的一处3栋临街高层建筑作为研究对象,在实验区城市噪声实测的基础上,以GIS的空间分析和地统计分析为主要手段对实测城市噪声数据进行空间分析,探究了城市噪音的空间分布规律。实验结果表明:垂直空间方向上,噪声垂向分布呈先增大后减小的趋势。噪声最大值出现在距噪声源垂直距离约35～45 m处;同时有一噪声低值区出现在距噪声源垂直距离约50～64 m处。
Urban noise pollution,one of the four social effects of pollution,has seriously limited the quality of urban residents’ life.The traffic noise has become a major source of environmental noise pollution.The severity of the urban noise pollution has stirred up a series of the living environmental issues and concerns.In order to know the vertical distribution of the urban noise,in this paper,three typical high building next to the urban road in Foshan city was selected as the urban noise monitoring site.Moreover,with GIS Spatial analysis and Geo-statistical analysis as main means,results show that along with the increasing distance from the test point to the ground the vertical distribution of noise first boosted up and then went down,and the urban noise reached its peak value in the vertical distance about 35 to 45 meters,approximately reached its lowest value in the vertical distance about 50 to 64 meters as well.
