广州市番禺区2003和2004年环境噪声监测结果分析

目的为改善和治理番禺区声环境质量提供可靠的依据。方法按照（GB8222—1982）《城市环境噪声监测方法》和《环境监测技术规范（噪声部分）》要求进行测定。结果2004年度各功能区昼间环境噪声达到国家标准，但较2003年有所上升；区域环境噪声优于《城市区域环境噪声标准》的规定范围，较2003年下降；道路交通噪声加权平均等效声级值为67．9dB（A），低于4类区昼间环境噪声标准，超标干线占总路段8．5％。结论该区声环境各项指标达到国家标准，但仍处于较高污染水平，需加强声环境的治理工作。

Monitoring of Environmental Noise in Panyu Distict of Guangzhou in 2003 and 2004

Objective To monitor the acoustic environment condition in Panyu district,provide evidences for improving and treating measures.Methods Some acoustic environment indexes were measured according to Chinese national standards.Results The environmental noise indexes during the day in 2004 accorded with national standard,but higher than those in 2003.The indexes of district environmental noise in 2004 accorded with national standard but lower than those in 2003.The weighted equivalent level of traffic noise was 67.9 dB(A),which was lower than daytime environmental noise of the 4th domain.Conclusion Each acoustic environment index achieves requirements of national standard,but the polluted level is high in some extent.So managements of acoustic environment should be strengthened.
