通过分析浙江省杭州市10种绿化树种的滞尘量和叶片中N、S、Cl等元素的含量，比较了这些树种对大气中粉尘、氯化物、硫化物、氮氧化合物等有害物质的吸收净化能力。单位面积滞尘量最高的树种是朴树，N、S、Cl吸收最高的树种分别是乌桕、银杏和杜鹃；乔木树种的全氮含量、全硫含量、单位面积滞尘量都比灌木树种的含量高，但是全氯含量比灌木树种的含量低；落叶树种的各净化指标平均值都比常绿树种的高

Abstract: |
|
This paper analyzed dust removal amount and the concentration of the elements N, S and Cl in leaves of 10 kinds of greening species in Hangzhou. The air purification ability of these species were compared. The results are as follows: among 10 kinds of species, the highest dust removal amount is in Celtis sinensis, and the highest concentration of N, S and Cl is found in Sapium sebiferum, Ginkgo biloba and Rhododendron spp., respectively. Compared to the shrub species, the tree species has higher amount of dust removal and concentration of N and S, but lower concentration of Cl. The air purification abilities of deciduous trees were higher than evergreen trees.
