摘　　要：为了揭示南京常见道路绿化树种叶片含硫量的差异性,选择4个采样点10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,南京化工厂和北京东路的太平门树木叶片含硫量高,南京林业大学和中山植物园树木叶片含硫量相对较低;部分树种叶片含硫量季节差异显著,除了女贞和法国冬青外,大多数树种叶片含硫量随春、夏、秋季节的变化基本呈现递增趋势.根据全年10种树木叶片平均含硫量大小进行分类,杨树、金叶女贞和二球悬铃木叶片含硫量相对较高,为第一类;桂花、红花檵木和女贞为第二类,叶片含硫量中等;法国冬青、香樟、小叶黄杨和撒金珊瑚叶片含硫量相对较低,归为第三类.In order to reveal the difference of foliage sulfur content of common road green trees in Nanjing,10 afforestation trees were selected in four sampling sites,and the sulfur content of leaves was analysed.The results indicate that there is obvious difference on the amount of foliage sulfur content for different tree species in different sites,the foliage sulfur content near Chemical Works and Door of Taiping-Beijing East Road is more higher than those near Nanjing Forestry University and Zhongshan Botanical Garden.The season variation of sulfur content for some trees is significant,the sulfur content of great majority trees basically increase according to seasonal variation of Spring,Summer and Autumn,except for Ligustum Lucidum and Viburnum awabuki.Tree species be assorted three classifications at the basis of foliage sulfur content all year round,Populus Canadensis,Ligustrun quihoui and Platanus hispanica are classified to the first category and sulfur content is higher,the second category includes Osmanthus fragrans,Lorpetalum chinense and Ligustum Lucidum,for those there is medium content.Viburnum awabukiare,Cinnamomum camphora,Buxus sinica and Aucubajaponica Var.variegate are classified to the third category and sulfur content is lower.
