| 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。

| Abstract: | 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/m2)> Prunus triloba Lindl.(2.2817±0.0387g/m2)>R.xanthina Lindl.(1.5975±0.1144g/m2)>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 americana L.(1.4977±0.1780g/m2)>Populus euphratica Oliv.(0.8622±0.2216g/m2)>Sophora japonica L.(0.5207±0.0928g/m2)>Robinia pseudoacacia cv.Idaho(0.3775±0.0780g/m2)>Salix babylonica L.(0.1330±0.1360g/m2) respectively.The amount of dust-retention per unit leaf area of shrub species is higher than arbor species. |
