摘要
为了了解无为县的环境噪声现状,在无为县进行了环境噪声监测,根据监测结果绘制了无为县白天三个时段的环境噪声等值线图,分析了研究区白天环境噪声分布情况和噪声污染程度,利用公路交通噪声预测模型对无为县主要交通噪声进行了预测.研究结果显示,无为县白天的环境噪声值分布于45.0dB^78.4dB之间,大部分区域环境噪声质量处于坏-恶化的级别,只有少数区域噪声环境较好,选用的公路交通噪声预测模型适用于无为县公路噪声的预测,预测结果显示无为县晚间最大交通噪声值为73.0dB.
In order to clarify the present situation of environmental noise in the county of Wuwei,environmental noise monitoring is carried out.According to results of monitoring,environmental noise contour maps of Wuwei County in three periods during a day are drawn,and the distribution of environmental noise and the degree of noise pollution in daytime are analyzed.The highway traffic noise prediction model is used to predict the main traffic noise in Wuwei County.Results show that the value of environmental noise is distributed between 45.0 dB and 78.4 dB in daytime.Environmental noise quality of most regions is at the level of bad-deterioration,and only a few areas has good noise environment.The highway traffic noise prediction model is applicable to the prediction of traffic noise in Wuwei county.The result of prediction shows that the maximum traffic noise value of Wuwei County is 73.0 dB in the evening.
