摘　　要：为了改善空气质量,优化人居环境。将小区内的绿化树木作为多孔介质来研究其对颗粒物的吸附作用,并比较分析了树木削减大气颗粒物的方法,同时通过实验的方法总结出了树木吸附颗粒物的时间变化规律。结果表明:吸附作用的减尘效果最佳,不同树种在一天之内的不同时间段和不同的季节吸附颗粒物的量不同。为植物吸附颗粒物提供理论支撑,以达到小区规划中能够选择高效吸附颗粒物的树种,也为树木配置方式的选择提供理论依据。In order to improve the air quality and optimize the living environment.Greening trees were seen as porous media to study the adsorption in the community,and themethods of trees reducing atmospheric Particulate matterwereanalyzed comparatively.Results showed that the dust reduction effect of adsorption is best,different tree species in different time periodsof one day and different season absorbthedifferent amount of paniculate matter.This provides theoretical suppon for plant adsorbing particles,in order to select the trees of efficient adsorption paniculate matter in the residential area planning,to provide theoretical basis for the choice of efficientconfiguration mode.
