摘要:植物对大气中的粉尘有滞留、吸附和过滤作用,因此,滞尘能力被看作是园林绿化树种选择的一个重要指标。采用水洗过滤法对磴口县10种绿化树种的单位叶面积滞尘量进行了测定。结果表明:不同树种的单位叶面积滞尘量存在显著差异,这主要是与植物叶片特性、树冠结构、枝叶密度、叶面倾角等差异有关。灌木树种单位叶面积滞尘量从大到小为玫瑰(2.7470±0.2033g/m2)>榆叶梅(2.2817±0.0387g/m2)>黄刺玫(1.5975±0.1144g/m2)>华北珍珠梅(1.2269±0.0262g/m2)>桃叶卫矛(1.0965±0.2103g/m2);乔木树种单位叶面积滞尘量从大到小为洋白蜡(1.4977±0.1780g/m2)>胡杨(0.8622±0.2216g/m2)>国槐(0.5207±0.0928g/m2)>香花槐(0.3775±0.0780g/m2)>垂柳(0.1330±0.1360g/m2)。灌木树种的单位叶面积滞尘量整体上大于乔木。
Plants can retain, adsorb or filter the dust in atmosphere, so the dust - retention ability is regarded as an important index for choosing landscaping tree species in city. The amount of dust - retention per unit leaf area of ten landscaping tree species were tested and analyzed using water filtering method in Dengkou, and the results showed that the dust - retention ability differs among the different landscaping tree species. This is mainly related to differences in plant leaves characteristics, crown structure, branches and leaves density, leaf angle, and so on. The dust - retention abilities of shrub species, from strong to weak, are Rosa rugosa Thunb. (2. 7470±0. 2033g/m^2) 〉 Prunus triloba Lindl. (2.2817±0.0387g/m^2 ) 〉 R. xanthina Lindl. ( 1. 5975±0. 1144g/m^2 ) 〉 Sorbaria kirilowii (Regel) Maxim. ( 1. 2269±0. 0262g/m2 ) 〉 Euonymus bungeana Maxim. ( 1. 0965±0. 2103g/m2) respectively; the dust -retention abilities of arbor species, from strong to weakl, are Fraxinus ameri- cana L. ( 1. 4977±0. 1780g/m^2 ) 〉 Populus euphratica Oliv. (0.8622±0.2216g/m^2 ) 〉 Sophora japonica L. (0. 5207±0. 0928g/m^2 ) 〉 Robinia pseudoacacia cv. Idaho(0. 3775±0.0780g/m^2 ) 〉 Salix±0. 1360g/m^2) respectively. The amount of dust -retention per unit leaf area of shrub arbor species. babylonica L. (0. 1330 species is higher than
