关于城市道路绿化滞尘降噪的探讨

摘要

The environmental pollutions caused by urban traffic include air pollution,noise,as well as the pollution status of traffic environment.Road greening can decrease air pollution and noise.The paper introduces the current study status of the ability of greening dust-retention and noise in our country in detail.The result showed that proper road greening can decrease the dust and noise to a certain level.The major problems of applying dust-retention and noise methods in northern China in winter are elaborated and the effective and economical method about dust-retention is in need.%介绍城市道路交通环境污染主要是大气污染和噪声污染以及目前的道路交通环境污染情况。论述城市道路绿化植物能够减低空气污染物和交通噪声,详细分析目前国内对道路绿化植物滞尘降噪能力的研究状况。研究表明,恰当的道路绿化能够起到一定的滞尘降噪作用。阐述目前的滞尘降噪措施在我国北方地区冬季时存在的主要问题,指出需要研发更加有效、经济、适应性更强的滞尘降噪措施。
