摘要
噪声污染一直是海口市主要的环境问题之一。主要原因是城市纵深度太低 ,道路密度太高 ,交通布局不合理 ,1991年— 2 0 0 0年城市区域环境噪声和道路交通噪声的平均值分别为 5 9.0dB(A)和 6 9.5dB(A)。利用城市区域环境噪声预测方法和道路交通噪声预测方法对该市噪声进行预测 ,2 0 0 1年— 2 0 0 5年该市的区域噪声昼间平均等效声级综合预测值在 5 7.6dB(A)～ 5 6 .7dB(A)之间 ;道路交通噪声昼间平均等效声级综合预测值在 6 8.2dB(A)～ 6 8.3dB(A)
Noise pollution is the key environmental pollution problem in Haikou. The reasons include that the city is too narrow, road density is too high and the communication allocation was ir reasonable. The average value of noise in urban region and around roads were 59.0 dB(A)-69.5 dB(A). The noise pollution was predicted, there would be between 57.6 dB(A)-56.7 dB(A) for urban region, 68.2 dB(A) -68.3 dB(A) for around roads.
