摘　　要：在2009年9月至2010年12月间,按照生态采样法,对南京市的6城区5郊区的106条主次干道及道路绿化带中的色叶树种的实际应用状况进行了深入调查。调查结果显示:目前共使用色叶树种26科35属44种,乔木有36种,灌木有8种。共调查色叶乔木15 293株,二球悬铃木与香樟所占数量最多,分别占将近5成和2成;大多数乔木的径阶在12～14 cm,树高在6 m,冠幅4 m以下的占一半。存在的主要问题是:色叶乡土树种资源得不到充分运用,春色叶、双色叶树种应用较少,部分色叶树种的配置与生态习性不符,养护管理过于粗放。The application of chromatic leaf tree in 106 road green belts in 6 districts and 5 surburbs in Nanjing was surveyed thoroughly from September,2009 to December,2010.The results showed that there were 44 species of chromatic leaf tree belonged to 26 families and 35 genera,including 36 species of arbor,and 8 species of bush.15293 chromatic leaf trees were investigated,among which Platanus hispanica and Cinnamomum camphora were ranked the first two in numbers,accounted for almost 50% and 20% of the whole trees investigated respectively.The diameter at breast-height and height of the most trees were between 12 to 14 cm,and 6 m respectively,and half of the trees investigated were below 4 m in crown coverage.There were some problems still existed.The resources of native trees were not applied sufficiently and the spring chromatic leaf trees and the chromatic double-leaf trees were relative less employed.The implement of some chromatic trees was not in accordance with their ecological habits and the management was a little bit rough.
