摘要
公路绿化带可对交通噪声和汽车尾气带来的铅(Pb)污染产生一定防护作用,这对于减轻路域环境污染具有重要意义。采用原位调查和取样分析相结合的方法,研究了山东省济青高速公路路侧绿化带对交通噪声和铅污染的衰减效果。研究结果表明,高速公路绿化带对交通噪声有一定的减轻作用,但在不同的绿化模式下,衰减效果存在较大差异。济青高速公路两侧土壤存在一定程度的Pb污染,在不同绿化模式下,路侧绿化林带对公路Pb污染的防护作用也有较大差别,宽度过大的林带并不是防护Pb污染的理想措施。
Traffic noise and Pb pollution from automobile exhaust can be decreased by green belts to some extent, which is important to reduce pollution in road environment. The attenuation of traffic noise and Pb pollution by green belts along Jinan-Qingdao expressway were studied by in-situ investigation and experimental analysis in this paper. The results indicated that green belts could reduce the traffic noise from expressway. However, the effects differed greatly among different greening patterns. Lead pollution...
