| 摘 要： | 粉尘是造成城市环境污染的主要组成部分,其飘落规律对道路绿化滞尘效果有着重要意义.通过道路灰尘飘落规律模拟实验和道路实验,以及常见绿化树种叶面积测算、室内模拟道路环境对各树种的滞尘能力的研究.结果表明,罗汉松滞尘量最大,为2.524 9 g/m~2,其次为红翅槭2.178 7 g/m~2,这两种树种的滞尘量明显高于其他树种.其他树种滞尘率大小排序为红叶石楠、海桐、女贞、广玉兰、樟树、杜英、含笑、大叶黄杨、山茶、冬青、桂花、小叶女贞、杜鹃.粉尘飘落则显示出在不同距离点,由近及远呈现规律递减的现象.

| Abstract: | Dust is the main component resulting in urban environmental pollution,the law of the falling is significant effect for dust removal by road greening.Though simulation of the law of the road dust and road experiment,and the estimation of the common green tree leaf area index,estimation,indoor simulation of the effect of road environment on the dust removing abihty of various species.The results showed that the dust removing rate of Podocarpus was the largest,which was 2.524 9 g/m~2,followed by red-winged maple,which was 2.178 7 g/m~2.The dust removing rates of these two species were significantly higher than those of others.The dust removing rates of other species followed the order:Photinia fraseri sort,Pittosporum,Ligustrum,Magnolia grandiflora,camphor tree,Elaeocarpus,Michelia,Euonymus,Camellia,holly,sweet-scented osmanthus,Lobular ligustrum and Rhododendron.Dust falling showed the law of diminishing from the nearer to the farther points. |
