摘　　要：由于城市化进程加快、工业的迅猛发展以及汽车尾气排放得不到控制等的影响,大气颗粒物已成为空气污染的罪魁祸首。通过绿化植物对大气颗粒物的吸附作用是国内外学者研究的热点问题。截至目前,大量研究主要集中在植物对粒径较大的TSP和PM10的吸附效应上,对PM2.5等细颗粒物的吸附研究仍处在探索阶段。本文概述了PM2.5沉降机制,从植物个体层面讨论了植物叶表面特征和植物结构特征对PM2.5的吸附影响研究进展,分析了不同的环境条件对吸附效应的影响结果以及探讨了植物吸附PM2.5的测定方法。通过对城市绿化植物吸附PM2.5影响因素的阐述,提出了绿化植物吸附PM2.53个方面的研究重点和趋势,为深化植物吸附PM2.5的研究机制和筛选对颗粒物较高吸附能力的植物提供科学理论依据。With the acceleration of urbanization,the rapid development of industry and the uncontrolled emission of automobile exhaust,atmospheric particulate matter has become the main cause of air pollution.The adsorption of air particles by greening plants is a hot topic at home and abroad.Up to now,a large number of studies have focused on the adsorption of TSP and PM10 with larger particle size,and the adsorption of PM2.5 and other fine particles is still in the exploratory stage.This paper summarizes the mechanism of PM2.5 deposition,discusses the research progress of adsorption effect of plant leaf surface characteristics and plant structure characteristics on PM2.5 from the plant individual level,analyzes the effect of different environmental conditions on the adsorption effect,and probes into the determination method of adsorbing PM2.5.Through elaborating the influencing factors of adsorbing PM2.5 by urban greening plants,the research emphases and trends on three aspects of adsorbing PM2.5 by greening plants are put forward,which provides scientific theoretical basis for deepening the research mechanism of adsorbing PM2.5 by plants and selecting plants with high adsorption capacity for particles.
