广州内环路的交通噪声地图(英文)

Traffic Noise Mapping of Guangzhou Inner Ring Road

城市发展建设中各样的问题干扰着人们的生活.广州中心区内环路的建设而引起的交通噪声更是极大地影响了中心区的环境.为了控制交通噪声污染,绘制交通噪声地图、管理和削减内环路的噪声水平是迫切需要的.文中将地理信息系统的数据整合于噪声模型中,利用内环路噪声监测的多项数据,通过噪声分析软件绘制了内环路的道路交通噪声地图.该噪声地图以可视化的方式展示了道路噪声状况,并预测了监测点的噪声水平.通过预测声级和实测道路噪声声级的比较,证明该噪声地图具有较高可信度,可作为中心区环境保护决策支持的工具.

The problems resulting from urban growth is continuously adding pressure on the everyday living of people in cities. With the rapid development of ring road construction in Guangzhou central area, the traffic noise pollution is increasing seriously. It is necessary to map, manage and reduce the noise. In this paper, a traffic noise survey of Guangzhoo inner ring road （IRR） is performed. According to the monitoring data, the traffic noise mapping of the rnad is then calculated by using the nnise analyzing software and by generating the Geographic Information System （GIS） data with acoustic models. The noise mapping, integrated with geographical information system data, reveals the noise condition in central urban areas in a visible way and helps to predict the noise levels. By comparing the predicted noise levels with the measured ones, it is found that the presented noise mapping is reliable and is useful for the decision making for the environmental protection in central urban areas.
