| 摘 要： | 以地处山西省晋中盆地的山西农业大学校园为试验区,研究了主要绿化树种单位叶面积(单位叶重)的滞尘能力和滞尘机理以及各树种的植株滞尘量。结果表明:植株间滞尘能力有较大差别。从叶片形态观察的结果可以看出:阔叶树中,叶面皱缩、多毛和具有分泌液树种的单位叶面积滞尘能力强;针叶树单位叶重滞尘量的差异主要是由于集生叶片数量不同和叶片的着生角度不同引起的。落叶乔木的植株滞尘量大于灌木。 |
| 关 键 词： | 绿化树种 叶面特征 滞尘量 |
Effect of Dust Catching Capacity of Common Virescence Tree Species in the North of China |
|
| Abstract: | Dust catching capacity in unit leaf area,dust catching mechanism and dust catching quantity per plant of main virescence tree species were studied in Shanxi Agricultural University,Jinzhong Basin,Shanxi Province.the result showed that the dust catching capacity of different tree species was prominently different.In view of leaf morphological structure,the broadleaf tree species with surface crimple,more hair and excrete liquid,dust catching capacity of unit leaf area was stronger;difference of dust catching quantity per unit leaf weight within conifer tree speices was mainly due to different collected number and inserted angle of leaf.From dust catching capacity per plant,the hardwood was letter than shrub. |
| Keywords: | Virescence tree species Facial characteristics of leaf Dust catching quantity |
