摘　　要：为了揭示镇江市常见绿化树种叶片含硫量的差异性,选择工业区(GYQ)、交通繁忙区(JTQ)、甘露寺(GLS)和南山景区(NSQ)4个采样点采集女贞、枫杨、杨树、红叶李、紫薇、大叶黄杨、法国冬青、红花檵木、金叶女贞、小叶黄杨和紫叶小檗11种绿化树木的叶片并对其含硫量进行分析。结果表明:不同采样点各树种叶片含硫量差异明显,工业区(GYQ)和交通繁忙区(JTQ)树木叶片含硫量高,甘露寺(GLS)和南山景区(NSQ)树木叶片含硫量相对较低。女贞、枫杨、杨树、红叶李、紫薇、大叶黄杨、法国冬青、红花檵木、金叶女贞、小叶黄杨和紫叶小檗叶片含硫量分别为0.247%、0.151%、0.863%、0.135%、0.128%、0.132%、0.271%、0.420%、0.401%、0.124%和0.136%,根据11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相对较高,划分为第1类;法国冬青和女贞居中,为第2类;枫杨、紫叶小檗、红叶李、大叶黄杨、紫薇和小叶黄杨较低,归为第3类。In order to reveal the difference of foliage sulfur content of common green trees in Zhenjiang, 11 afforestation trees of Ligusturn lucidum , China wingnut , Populus canadensis , Prunus cerai fera , Lagerstroemia indica , BUZUS megistophylla , Viburnum awabuki , Lorpetalum chinevlse , Ligustrun quihoui , Buzus sinica , Berberis thunbergti var. atropurpurea were selected in four sampling sites of industrial pack（GYQ）, traffic area （JTQ）, Ganlu temple（GLS） and Nanshan scenio spb（NSQ） ,and the sulfur content of leaves were analyzed. The results indicated that there was obvious difference on the amount of foliage sulfur content for different tree species in different sites, the foliage sulfur content near GYQ and JTQ functional area was more higher than those near GLS and NSQ functional area. Foliage sulfur content of Ligusturn lucidurn ,China wingnut , Populus canadensis , Prunus cerai f era , Lagerstroemia indica , Buxus megistoph ylla , VibUrnum avaabuki ,Lorpetalurn chinense, Ligustrun quihoui, Buxus sinica, Berberis thunbergii var. atropurpurea were respectively 0. 247%,0. 151%,0. 863%,0. 135%,0. 128%,0. 132%,0. 271%,0. 420%,0. 401%,0. 124% and 0. 136%. Tree species were assorted three classifications at the basis of foliage sulfur content, Populus canadensis, Lorpetalurn chinense and Ligustrun quihoui were classified to the first category and sulfur content was the higher,the second category includes Viburnum avc%ztruki and Ligustum lucidum, for them there was medium content. China wingnut, Berberis thunbergii var. atropurpurea, Prunus cerai fera , Buxus megistophylla , Lagerstroemia indica and Buxus sinica were classified to the third category and sulfur content was the poorer.
