摘要
对长春市街道绿化常用的4种灌木进行了滞尘效应的研究。结果表明,不同树种单位叶面积的滞尘能力存在很大差异,4种植物的滞尘能力大小为金山绣线菊>辽东水蜡>毛丁香>茶条槭。植物叶片的滞尘量不是随时间无限增长的,随着滞尘时间的延长,单位时间内的滞尘量缓慢减少。植物叶片的滞尘能力与环境中的降尘量以及滞尘时间有关,植物不同的叶表面结构也对其有一定的影响。该研究为长春市街道绿化树种的选择提供了参考依据。
The dust retention capacity of 4 ordinary shrubs along the roads was determined in Changchun.The result showed that the dust catching capacity of different tree species was prominently different and the capacity order was Spiraea X bumalda ＇Goalden Mound＇Ligustrum obtusifuliumSyringa tomentellaAcer ginnala.The dust retention capacity of the shrub increased with time during a certain time.As the time delay,dust absorption ability of shrubby tree species were slowly decreased within the unit.Dust absorption abilities of shrubby tree species were related to environment and the time of dust absorption.The structure of leaf vein contained a certain influence on the dust removal effect.The study will provide a reference basis for greening tree species selecting along streets of Changchun City.
