摘　　要：为分析江苏省常州市绿化树木叶片含硫量的差异性,选择3个采样点15种绿化树木的叶片并对其含硫量进行分析,结果表明,不同采样点各树木叶片含硫量差异明显,工业区(GYQ)和闹市区(NSQ)树木叶片含硫量高,清洁区(QJQ)树木叶片含硫量相对较低。香樟(Cinnamomum camphora)、大叶女贞(Ligustum lucidum ait)、枫杨(China Wingnut)、垂柳(Salix babylonica)、杨树(Populus canadensis)、紫叶李(Prunus ceraifera)、撒金珊瑚(Aucuba japonica Var.variegate)、紫薇(Lagerstroemia indica)、大叶黄杨(Buxus megistophylla)、法国冬青(Viburnum awabuki)、雪松(Cedrus deodara)、红花檵木(Lorpetalum Chi-nense)、金叶女贞(Ligustrun quihoui)、红枫(Acer palmatum)和紫叶小檗(Berberisthunbergii cv.atropur-purea)叶片含硫量分别为0.124%、0.234%、0.144%、0.170%、0.866%、0.139%、0.232%、0.130%、0.158%、0.171%、0.130%、0.368%、0.325%、0.154%、0.147%。根据15种树木叶片平均含硫量大小进行分类,杨树、红花檵木和金叶女贞叶片含硫量相对较高,划分为第一类;大叶女贞和撒金珊瑚居中,为第二类;法国冬青、垂柳、大叶黄杨、红枫、紫叶小檗、枫杨、紫叶李、紫薇、雪松和香樟较低,归为第三类。In order to reveal the difference of foliage sulfur content of afforestation trees in Changzhou city of Jiangsu province, 15 afforestation trees were selected in three sampling sites, and the sulfur content of leaves was analyzed. The re- sults indicated that there was obvious difference on the foliage sulfur content for tree species in different sites, the foliage sulfur content near GYQ and NSQ functional area was higher than those near QJQ functional area. Foliage sulfur content of Cinnamomum camphora, Ligustum lucidum ait, China Wingnut, Salix babylonica, Populus canadensis, Prunus ceraifera, Au- cuba japonica Var. variegate, Lagerstroemia indica, Buxus megistophylla, Viburnum awabuki, Cedrus deodara, Lorpetalum Chinense, Ligustrun quihoui, Acer palmatum, Berberisthunbergii cv. atropurpurea were 0.t24%, 0.234%, 0.144%,0.170%, 0.866%, 0.139%, 0.232%, 0.130%, 0.158%, 0.171%, 0.130%, 0.368%, 0.325%, 0.154% and 0.147% respectively. 15 af- forestation trees were assorted into three classifications on the basis of foliage sulfur content, P. conadensis, L. Chinense and L. quihoui were classified to the first category and sulfur content was higher, the second category included L. lucidum ait and Aucuba japonica Var. variegate, for them there were medium sulfur content. V. awabuki, S. babylonica, B. megistophyl- la, A. palmatum, Berberisthunbergii cv. atropurpurea, China Wingnut, P. ceraifera, L. indica, C. deodara, and C. camphora were classified to the third category and sulfur content was lower.
