摘　　要：为揭示安阳市绿化树种的滞尘规律,选择3个功能区12种绿化树木对其叶片滞尘量进行分析。结果表明,毛白杨(Populus tomentosa Carr.)、国槐(Sophora japonica L.)、紫叶李(Prunus cerasifera Ehrh.f.atropupurea Rehd.)、臭椿[Ailanthus altissima(Mill.)Swingle]、大叶女贞(Ligustum lucidum Ait.)、白蜡(Fraxinus chinensis Roxb.)、枇杷[Eriobotrya japonica(Thunb.)Lindl.]、栾树(Koelreuteria paniculata Laxm.)、小叶黄杨[Buxus sinica(Rehd.et Wils.)Cheng ex M.Cheng subsp.sinica var.parvifolia M.Cheng]、紫荆(Cercis chinensis Bunqe)、构树[Broussonetia papyrifera(L.)L'Hér.ex Vent.]、椤木石楠(Photinia davidsoniae Rehd.et Wils.)的单叶滞尘量分别为8.144、1.912、2.993、4.512、2.139、0.936、55.552、1.398、0.190、8.172、5.417和0.465 mg,单位面积滞尘量分别为0.344、0.366、0.309、0.484、0.101、0.054、0.841、0.132、0.625、0.067、0.194和0.113 mg/cm2。以枇杷和小叶黄杨的叶片单位面积滞尘能力较强,构树、栾树、椤木石楠、大叶女贞、紫荆和白蜡相对较弱,臭椿、国槐、毛白杨和紫叶李居中。对单叶滞尘量而言,枇杷、紫荆和毛白杨的最大,构树、臭椿、紫叶李、大叶女贞、国槐和栾树居中,白蜡、椤木石楠和小叶黄杨最小。In order to reveal the regularity of dust detention of green trees in Anyang city,the dust detention quantity on leaves of 12 green trees in 3 functional districts was analyzed.The results indicated that unifoliate dust detention of Populus tomentosa Carr.,Sophora japonica L.,Prunus cerasifera Ehrh.f.atropupurea Rehd.,Ailanthus altissima（Mill.） Swingle,Ligustum lucidum Ait.,Fraxinus chinensis Roxb,Eriobotrya japonica（Thunb.） Lindl.,Koelreuteria paniculata Laxm.,Buxus sinica（Rehd.et Wils.） Cheng ex M.Cheng subsp.sinica var.parvifolia M.Cheng,Cercis chinensis Bunqe,Broussonetia papyrifera（L.） L＇ Hér.ex Vent.,Photinia davidsoniae Rehd.et Wils.was 8.144,1.912,2.993,4.512,2.139,0.936,55.552,1.398,0.190,8.172,5.417,0.465 mg respectively,and the dust detention per unit area was 0.344,0.366,0.309,0.484,0.101,0.054,0.841,0.132,0.625,0.067,0.194,0.113 mg / cm2respectively.The per unit area dust capture ability of E.japonica and B.sinica was better,of B.papyrifera,K.paniculata,P.davidsoniae,L.lucidum,C.chinensis,F.chinensis was poorer,of A.altissima,S.japonica,P.tomentosa and P.cerasifera f.atropupurea was in between.As for the unifoliate dust detention,E.japonica,C.chinensis and P.tomentosa were stronger,B.papyrifera,A.altissima,P.cerasifera f.atropupurea,L.lucidum,S.japonica and K.paniculata were in between,F.chinensis,P.davidsoniae and B.sinica were poorer.
