摘　　要：为揭示新乡绿化树木的单叶滞尘量,选择20种绿化树木并对其单叶滞尘量进行比较。结果表明,毛白杨、银白杨、悬铃木、国槐、银杏、臭椿、大叶女贞、枇杷、紫叶李、紫丁香、红叶石楠、椤木石楠、白蜡、构树、紫荆、大叶黄杨、小叶黄杨、凤尾兰、小叶女贞和海桐单叶滞尘量分别为6.555、5.813、11.874、0.142、0.520、3.336、3.487、42.660、0.639、0.524、0.318、0.377、3.774、5.994、6.634、0.738、0.157、1.694、1.268、0.855 mg。枇杷单叶滞尘量较高,归为第1类;毛白杨、银白杨、悬铃木、构树、紫荆归为第2类;国槐、银杏、臭椿、大叶女贞、紫叶李、紫丁香、红叶石楠、椤木石楠、白蜡、大叶黄杨、小叶黄杨、凤尾兰、小叶女贞和海桐单叶滞尘量相对较低,归为第3类。In order to reveal the unifoliate dust detention of city green trees in Xinxiang, 20 afforestation trees were selected and the unifoliate dust detention was analysed. The results indicated that unifoliate dust detention of Populus tomentosa Cart, P. alba, Platanus hispanica, Ophora japonica Linn, ginkgo, A ilanthus altissima, Ligustrum lucidum Air, Eriobotrya japonica, Prunus, Syringa oblata, Hotinia serrulata, P. davidsoniae, Fraxinus chinensis, Papermulberry, Cercis chinensis, Buxus megistaphylla, B. sinica, Yucca gtoriosa, L. quihoui and Pittosporum tobira were respectively 6.555, 5.813,11.874,0.142,0.520,3.336,3.487,42.660, 0.639,0.524,0.318,0.377,3.774,5.994, 6.634,0.738,0.157,1.694,1.268 and 0.855 mg. The capture of unifoliate dust detention by E. japonica were the best and belonged to the first category, the second category included P. tomentosa Cart, P. alba, P. hispanica, Papermulberry and C. chinensis, and were in the intermediate level, O. japonica Linn, ginkgo, A. altissima, L. lucidum Ait, Prunus, S. oblata, H. serrulata, P. davidsoniae, F. chinensis, B. megistophylla, B. sinica, Y. gloriosa, L. quihoui and P. tobira were in the third category.
