中文摘要：

选择30种适于北方生长的优良景观树种,其中国内引进树种10种、乡土树种20种,分别对他们的滞尘、杀菌和吸收SO2的能力进行测定。结果表明,在所有研究的树种中,金老梅、紫花锦鸡儿、银老梅、七姐妹和松东锦鸡儿的滞尘效果最好,可作为灰尘污染较重地区的绿化植物;华北绣线菊、松东锦鸡儿、早花忍冬、玫瑰和山槐杀菌能力最强,可在医院、城市街道等细菌较多的地方栽植;紫花锦鸡儿、短梗五加、银老梅、藏花忍冬和玫瑰吸收SO2量较大,可作为工厂、发电厂等排放SO2较多地区的绿化材料。

英文摘要：

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.
