太原市环境噪声质量现状剖析

On the present situation of environmental noise in Taiyuan City

以1996～2000年太原市区域环境噪声和道路交通噪声数据为基础,对平均等效声级、达标率及暴露在不同等效声级下的路段分布情况进行了比较分析。通过对声源结构分布状况分析,指出了生活噪声和交通噪声是影响太原市区域环境噪声的主要声源,并根据近年来太原市机动车辆急剧增加、交通基础设施的建设情况等对太原市的环境噪声质量现状进行了剖析,进一步从加强城市规划研究、积极开展宣传教育工作等5个方面探讨了综合治理太原市环境噪声的控制对策。

Based on the data of regional environmental noise and roadside traffic noise in Taiyuan City in the years from 1996 to 2000,the average level of noise and the rate of reaching standard are analyzed as well as the noise distribution in different sections of the roads which are exposed to different noise levels. Through analyzing the distribution of noise sources,it is pointed out that living noise and traffic noise are the primary noise sources of the regional environmental noise of Taiyuan City. Although the numbers of the automobile increase rapidly during these years,the roadside traffic noise has been up to the State Standard owing to the contribution of the road construction. The treatment countermeasures are discussed such as strenghening the research on the city planning,promoting actively the environmental education of general public.
