摘　　要：为了揭示新乡城市绿化树种的滞尘规律,选择3个功能区9种绿化树木对其叶片滞尘量进行分析。结果表明,悬铃木、构树、紫叶李、女贞、国槐、凤尾兰、栾树、大叶黄杨和白蜡单叶滞尘量分别为11.591、5.313、2.841、2.146、1.698、1.517、1.325、1.142、0.635mg,其中,悬铃木与构树、紫叶李具有显著性差异,与其他树种具有极显著性差异,白蜡与构树具有显著性差异。国槐、凤尾兰、紫叶李、大叶黄杨、构树、栾树、女贞、悬铃木和白蜡叶片单位面积滞尘量分别为0.385、0.321、0.310、0.241、0.166、0.128、0.097、0.088、0.054mg/cm2。国槐、凤尾兰、紫叶李叶片单位面积滞尘能力较强,悬铃木、女贞、白蜡相对较弱,大叶黄杨、构树、栾树居中。树种和功能区对树木叶片单位面积滞尘量有极显著影响。In order to reveal the dust detention laws of city green trees in Xinxiang,9 afforestation trees were selected from three functional districts, and the amount of dust detention was analysed. The results indicated that the amount of unifoliate dust detention of Platanus hispanica, Paper-mulberry, Prunus cerasi fera , Ligusturn Lucidurn , Sophora japonica Linn. ,Yucca gloriosa , Koel-reuteria paniculata , Buxus rnegistophylla , Fraxinus chinensis was respectively 11.591 mg, 5.313 mg,2. 841 mg,2. 146 mg,1. 698 mg, 1. 517 mg,1. 325 mg,1. 142mg and 0. 635 mg,and unit area dust detention of Sophora japonica Linn,Yucca gloriosa , Prunus cerasi f era , Buxus rnegistoph yl-la , Pa perrnulberry , Koelreuteria paniculata , Ligusturn lucidurn , P latanus hispanica and Fraxi-nus chinensis was respectively 0. 385 mg/cm^2 , 0. 321 mg/cm^2 , 0. 310 mg/cm^2, 0. 241 mg/cm^2, 0. 166 mg/cm^2 ,0. 128 mg/cm^2,0. 097 mg/cm^2 ,0. 088 mg/cm^2 and 0. 054 mg/cm^2. The capture of particulate pullution by Sophora japonica Linn. ,Yucca gloriosa and Prunus cerasifera was the best, but Platanus hispanica ,Ligusturn lucidurn, and Fraxinus chinensis gave the worst results, Buxus rnegistophylla, Paperrnulberry and Koelreuteria paniculata were in the intermediate le-vel. As far as unifoliate dust detention,in comparison to Paperrnulberry and Prunus cerasifera, Platanus hispanica had striking difference,and significant difference was found between Platanus hispanica and the other,between Fraxinus chinensis and Paperrnulberry. Trees and the functio-nal district had siginificant effect on the amount of unit area dust detention.
