【 摘 要 】

With 11 kinds of common ecological tree species in Hunan Province as the research object, the absorption amount of PM2.5 particles in the air per unit leaf area were studied to reveal the main ecological tree species in Hunan Province to reduce the air PM2.5 particles capacity. The results showed that the adsorption amount of PM2.5 per unit leaf area of different tree species each were not identical, mainly effected by foliage microstructure, branches and leaves density, leaf texture and the leaf angle. The order of PM2.5 adsorption quantity per unit leaf area of selected tree species for Cunninghamia lanceolate >Pinus massoniana > Cyclobalanopsis glauca> Castanopsis sclerophylla >Liquidambar formosana >Robinia pseudoacacia >Schima superba >Paulownia tomentosa >Pinus elliottii=Cupressus funebris > Alnus cremastogyne.
