摘要: 为研究天津市冬季常绿植物的滞尘能力,以校园、公园、道路旁为样地,选择其中的10种常绿植物为样株,测定了植物单位叶面积滞尘量和单株总滞尘量。结果显示:道路旁植物的滞尘量最高(5.757 1 g/m2)、其次是校园(4.502 7 g/m2),公园最低(3.979 0 g/m2);10种植物的单位叶面积的滞尘量为2.358 5~7.458 1 g/m2,滞尘量从大到小依次为:大叶黄杨>白皮松>小叶黄杨> 圆柏>黑松>油松>凤尾兰>沙地柏>雪松>龙柏;常绿绿篱及地被类植物单株总滞尘量依次是沙地柏(1.073 3 kg/株)、大叶黄杨(0.916 3 kg/株)、小叶黄杨(0.463 6 kg/株)、龙柏(0.428 8 kg/株);常绿松柏类乔木单株总滞尘量依次是圆柏(19.592 7 kg/株)、黑松(1.653 3 kg/株)、白皮松(0.776 3 kg/株)、油松(0.461 3 kg/株)、雪松(0.407 1 kg/株)。其中,圆柏的单株总滞尘量是其他常绿乔木的12~48倍,是很好的降尘树种。沙地柏和大叶黄杨是滞尘能力较强的地被植物和绿篱。

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.
