吉林农业大学主要乔灌木滞尘能力研究

Study on Dust-holding Capacity of Main Trees and Shrubs in Jilin Agricultural University

通过对吉林农业大学校园内及其缓冲带27种常见绿化树种的滞尘能力进行测定,分析比较同一绿化植物在不同街区和不同植物在同一街道的滞尘能力,结果表明不同绿化树种的滞尘能力差异明显。单位叶面积滞尘能力是灌木类>乔木类,灌木类的小叶丁香(10.3252~16.5612g/m^2),东北珍珠梅(4.2244~4.6389g/m^2)滞尘效果最好,接骨木,榆叶梅,紫丁香、茶条槭次之,皂角滞尘效果最差。乔木类的桃叶卫矛滞尘效果最好,黄檗,稠李滞尘效果次之,加杨、白桦、水曲柳、山荆子效果较差。

The dust retention ability of 27 common green trees in the campus of Jilin Agricultural University and its buffer zone were measured,the dust tolerance of the same green plant in different neighborhoods and different plants in the same street were analyzed and compared.The results showed that the dust retention capacity of different green trees were different.The dust retention of shrubs were greater than that of arbor.Dust retention of Sytinga microphylla(10.325 2-16.561 2 g/m 2),Sorbaria sorbifolia(4.224 4-4.638 9 g/m 2)were better than other plants,followed by Sambucus williamsii,Prunus triloba,Syringa oblata,Acer ginnala,Malus baccata was the worst.Euonymus bungeanus Maxim.had the best dust retention effect,followed by Phellodendron amurense and Prunus padus,Populus canadensis,Betula platyphylla,Fraxinus mandshurica,Mauls baccata were poor.
