摘要
采用显微计数法对邢台市区常见园林阔叶植物叶片滞霾效果进行比较研究。结果表明,不同植物种间滞霾效果存在显著差异。从滞霾数量来看,灌木植物呈现出强、弱分化的现象,迎春滞霾数量最多,月季滞霾量较少;从吸附灰霾颗粒直径大小来看,紫叶李对PM10以下的灰霾颗粒吸附率比较高;从灰霾数量和直径综合来看,滞霾效果表现最好的是榆树。植物滞霾能力并不是由单一因素决定的,具有枝条茂密紧凑、叶片小而硬、叶柄短小、叶表面粗糙有绒毛、能分泌粘液等特征的植物滞霾能力较强。此外,叶片的粗糙程度对吸附灰霾颗粒的大小有一定筛选作用。
The smog detaining effects of several species of common garden broad-leaved plants in Xingtai were studied by microscope counter method. The results showed that there are significant differences in smog detaining effects between the species of plants. In the respect of smog particles amount, the shrubs showed polarization of strong and weak smog detaining effect. The amount of smog particles detained by Jasminum nudiflorum is the most while that of Rosa chinensis is the least. In the respect of detained smog particles diameters, the percentage of PMIO detained by Prunus cerasifera is the highest. In the respect of synthesis of smog particle amounts and diameters, Ulmus pumila showed the best smog detaining effect. Smog detaining ability is effected by many factors. The plant which possess the characteristics of thick branches, small and hard leaves, rough leaf surface, leaf pubescent and secreting mucus had the stronger smog detaining effect. In addition, the roughness of the leaves has effect in the diameters distribution of detained smog particles
