新疆农业大学校园主要绿化植物滞尘能力初探

Preliminary Study on the Dust Catching Properties of Major Afforestation Plants in Xinjiang Agricultural University

对新疆农业大学校园内19种主要绿化植物进行了滞尘能力测定。结果表明，不同类型植物滞尘能力差异显著，灌木植物表现出极强的滞尘能力，其滞尘能力与藤本、落叶乔木在0．05水平有差异，滞尘能力的顺序为：灌木〉藤本〉阔叶乔木。同一类型的不同植物的滞尘能力也存在差异，有的可相差2～15倍以上。针叶树种中，油松平均滞尘量达到5．27g/kg；灌木植物中，树锦鸡儿和榆叶梅是优良的滞尘植物，平均滞尘量分别达到36．82和23．52g／m2；乔木植物中，以圆冠榆的滞尘量最大。

Dust catching properties of 19 major afforestation plants in Xinjiang Agricultural University were determined. The results showed that there were significant differences among different communities. Shrub plant showed extremely strong dust catching property, and it had differences at 0.05 levels with liana and defoliation arbor. The order of dust catching properties were shrub 〉 liana 〉 broad arbor. And those in the same communities were also different, some differences could reach over 2 -15 times. The average dust catching properties of Pinus tebu- laeformis was up to 5.27 g/kg, Caragana arborescensis （ 36.82 g/m2 ） and Prunus triloba （23.52 g/m2 ） were excellent dust catching plants a- mong shrubs, and the ideal plant among arbors was Ulmus pumila.
