摘　　要：为了揭示濮阳常见道路绿化树种叶片含硫量的差异性,于2011年春、夏、秋季对市区不同路段29种绿化树木的叶片含硫量进行比较,结果表明:不同季节部分树种叶片含硫量差异显著,除了大叶女贞和侧柏外,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29种树木叶片平均含硫量大小进行分类,毛白杨和圆柏含硫量较高,归为第1类;黑松、桂花、悬铃木和银杏叶片含硫量居中,归为第2类;泡桐、楝树、火棘、红叶李、榆树、合欢、垂柳、大叶女贞、银白杨、紫薇、杨树、侧柏、小叶黄杨、刺槐、雪松、白蜡、广玉兰、栾树、红叶石楠、海桐、构树、大叶黄杨和国槐叶片含硫量相对较低,归为第3类。In order to reveal the difference of foliage sulfur content of common road green trees in Puyang, 29 afforestation trees were selected in different roads and different seasons in 2011, and the sulfur content of leaves was compared. The results indicated that there is significant difference on the amount of foliage sulfur content for some tree species in different seasons, the foliage sulfur content of great majority trees were basically increasing with season changes of Spring,Summer and Autumn, except for Ligustrum lucidam A it and Platycladus orientalis （Linn.） Franco. Tree species were assorted three classifications at the basis of foliage mean sulfur content, Populus tomentosa Carr and Sabina chinensis （Linn.） Ant were classified to the first category and sulfur content is higher, the second category includes Cedrus, Osmanthus fragrans, Platanus hispanica and ginkgo , Paulownia, Melia azedarach, Pyracantha fortuneano, Prunus ceraifera cv. Pissardii, Ulmus pumilo, Albizia julibrissin Durazz, Salix babylonica, Ligustrum lucidum Ait, Populus albo, Cercis chinensis, Populus Canadensis, Platycladus orientalis （Linn.） Franco, Buxus sinica, Black Locust, Cedrus, Fraxinus chinensis, Magnolia grandiflora linn, Koelreuteria paniculato, Photinia serrulata, Pittosporum tobiro, Papermulberry, Buxus megistophylla and Sophora japonica Linn. were classified to the third category and sulfur content is lower.
