【摘要】：宝鸡市地处西北部平原,是连接东西部的重要交通要道,市内三区九县,一个高新技术产业开发区,主要道路有经二路、新建路、红旗路、公园路、火炬路、清姜路、中山路、高新大道等。根据宝鸡市近些年各监测代表点的环境噪声污染现状资料,分析和讨论了宝鸡市各条道路近几年的交通噪声污染特征,对不同季度不同类型噪声变化特征进行了对比分析。结果表明,宝鸡市功能区环境噪声等效连续A声级(Leq)虽然近期逐年小幅度增长,但还是在一定的可控制范围内,声学环境基本保持稳定状态。工业区噪声情况有所好转,而交通密集区、社会生活区则相对比较差,虽然超出标准限值,但不明显。相比较而言,建筑施工噪声Leq相对平稳且平均低于标准限值。宝鸡市城区噪声超标现象大部分集中在一些街道两侧的老旧工厂、工业居住混合区和铁路公路等道路交通要道两侧。居住工业混合区环境噪声质量状况较严峻,混合区的Leq波动比较平稳。交通干线两侧环境噪声从2008年起开始有所增高,尤其是夜间升高现象较严重。对各功能区环境噪声Leq值、各种噪声源在噪声污染中所占比例进行统计分析,评价了各区域的环境噪声污染状况,结果基本反映了目前宝鸡市噪声污染的实际情况,这对今后继续研究宝鸡市噪声污染动态变化规律奠定了良好的基础。最后,根据对宝鸡市城市道路、功能区噪声的实地调查与评价结果,针对宝鸡市目前环境噪声污染治理方面存在的不足,提出了相应的改进措施。本研究可为宝鸡市政府相关部门在环境噪声污染治理与管理方面的决策提供参考。
[Abstract]:Baoji city is located in the northwest plain, is an important transportation hub connecting the East, nine counties and three districts of the city, a high tech Industrial Development Zone, the main road two road, new road, Hongqi Road, Park Road, Torch Road, Jiang Qing Road, Zhongshan Road high road. According to the environmental noise pollution the status data of Baoji city in recent years on behalf of each monitoring point, the Baoji city in the last few years the road traffic noise pollution characteristics analysis and Discussion on the change of characteristics of different types of noise in different seasons were compared. The results show that the functional district of Baoji city environmental noise equivalent continuous A levels (Leq) despite the recent small increase year by year, but still can be controlled in a certain range of acoustic environment remained stable. Industrial Zone noise is improved, and the traffic area, social living area is relatively poor, although beyond the standard limit, but not obvious. In comparison, the limit value of construction noise Leq is relatively stable and the average lower than the standard. Baoji City exceed the standard phenomenon mostly in some noise on both sides of the street of the old factory, industrial mixed residential area and the railway highway traffic arteries on both sides. The environmental noise quality of the residential industrial mixing zone is more serious, Leq wave mixing area comparison smooth traffic arteries on both sides of the environmental noise began increased since 2008, especially at night increased severely. The functional areas of environmental noise Leq, various noise sources in noise pollution in the proportion of statistical analysis, evaluation of the environmental noise pollution situation in different regions, the results basically reflect the actual situation of noise pollution in Baoji the city, which laid a good foundation for further changes of pollution dynamic noise of Baoji city. Finally, according to the road of Baoji city, Investigation and evaluation of the results of functional area noise, aiming at the shortage existed in Baoji environmental noise pollution, the corresponding improvement measures were proposed. This study provides references for the relevant departments of the Baoji municipal government decision-making in environmental noise pollution control and management.
