Abstract: In order to understand the capacity of evergreen plants on dust retention in the winter in Tianjin, the dust deposition per leaf and plant among ten species planted in campus, park and street were measured. The results showed that plants on the side of the street had the most dust accumulation(5.757 1 g/m2), then was in the campus(4.502 7 g/m2), and the least in the park(3.979 0 g/m2); The average dust accumulation per unit leaf area of the ten species was range from 2.358 5 g/m2 to 7.458 1 g/ m2, and the dust capacity of these plants were Euonymus japonicus>Pinus bungeana>Buxus sinica>Sabina chinensis>Pinus thunbergii>Pinus tabulaeformis>Yucca gloriosa>Sabina vulgaris>Cedrus deodara>Sabina chinensis. The dust capacity of four evergreen hedgerows and cover plant was followed by Sabina vulgaris(1.073 3 kg/plant), Euonymus japonicas(0.916 3 kg/plant), Buxus sinica(0.463 6 kg/plant), Sabina chinensis(0.428 8 kg/plant)from more to less sequencing. The dust accumulation per plant of the five kinds of arbors were decreased in the order of Sabina chinensis(19.592 7 kg/plant), Pinus thunbergii(1.653 3 kg/plant), Pinus bungeana(0.776 3 kg/plant), Pinus tabulaeformis(0.461 3 kg/plant), Cedrus deodara(0.407 1 kg/plant). Meanwhile, the dust accumulation per plant of Sabina chinensis was 12-18 times as lager as other arbors. Therefore Sabina chinensis is a pretty good dust tree species. Sabina vulgaris and Euonymus japonicus were stronger in dust retention capacity in evergreen hedgerows and cover plant.
