He Yong,Li Lei,Li Junyi,Li Weixing,Mu Liqiang(School of Forestry,Northeast Forestry University,Harbin 150040,P. R. China)  
A study was conducted to determine the capabilities of dust detaining,sterilization,and SO2 absorption of 30 species of superior landscape trees,including 10 domestically introduced species and 20 native tree species. Result shows that,in all the species studied,Potentilla fruticosa,Caragana rosea,Potentilla davurica,Rosa multiflora var. carnea and Caragana ussuriensis have the best effect on dust detaining,which can be applied as the afforestation plants in the seriously dust polluted area. Spiraea fritschiana,Caragana ussuriensis,Lonicera praeflorens,Rosa rugosa,and Maackia amurensis exhibit stronger sterilizing capacity,which can be planted in the areas where bacteria pollution is high,such as hospital and city streets. C. rosea,Acanthopanax sessiliflorus,P. davurica,Lonicera tatarinowii and R. rugosa,having strong sulfur dioxide absorption performances,are suitable to be planted in factories,power stations and so on.
