摘要
通过野外调查和查阅相关资料,对上海市木本植物种类进行了统计整理,并对上海木本植物的组成、来源、变化和区系等特征进行统计分析,结果表明:上海具有木本植物87科304属721种(含亚种、变种和变型),由于大规模植物引种等作用,上海外来木本植物比例远高于乡土木本植物,呈现出高度城市化发展,而形成独特的木本植物多样性,而上海温带成分木本植物的引种明显多于热带成分,还对上海木本植物多样性的保育进行探讨。
In this paper, 721 woody plants including infraspecific taxa which belong to 87 families and 304 genera in Shanghai were reported. The composition, sources, changes and distribution lypes of genera were analyzed. The results showed that the percentage of the exotic and cultivated woody plants was obviously higher than that of the native. And the woody plants introduced from the temperate zone were more than that of the tropics. Furthermore, some approaches on woody plant diversity conservation in Shanghai were also discussed.
