Abstract: Garden plants have a significant ability to remove air particulate matters（ PM） and can effectively improve the urban environmental quality. The study of dust-retention effect of garden plants in China and other countries have made considerable achievements so far. However,most researches on the dust-retention effect of garden plants had been primarily concentrated on the total suspended particulates（ TSP） and coarse particles（ PM10）,while few studies have focused on the effects of plants’ adsorbing air fine particulate matter（ PM2. 5）. In order to provide references for further study in the PM2. 5adsorption capacity and adsorption mechanism of garden plants,we have concluded that the effects of garden plants’ adsorption of PM2. 5according to different perspectives,i. e.,the way of plant leaves absorbing air particles,the transfer process of PM2. 5upon leaves and the PM2. 5adsorption periodicity of plant leaves,the characteristics of adsorption of plant leaves to different diameter particles,the garden plants’ ability and mechanism of adsorbing PM2. 5. Additionally,we propose that the key points and trends about garden plants absorbing PM2. 5based on three aspects: the quantitative analysis method of PM2. 5removal efficiency of garden plants,the measurement and evaluation of garden plants’ adsorption abilities to PM2. 5,selection of plants with a higher ability to adsorb PM2. 5,the mechanism and influencing factors of garden plants’ adsorption to PM2. 5. The present paper provides a basis for deepening the research on the mechanism of plant adsorbing PM2. 5and selection of garden plants with a high ability of adsorption to PM2. 5.
