上海江湾机场植物群落多样性研究

Study on Diversity of Plant Community at Jiangwan Airport, Shanghai

以市区内江湾机场失去管理后出现的自然植被为研究对象,通过群落学调查研究,分析了群落的种类组成以及结构特征,阐明了群落的恢复过程和潜力。结果表明,江湾机场的植被可划分为4个外貌类型、16个群落类型。自然植被表现为以草本群落为主、辅以少量木本植物群落为特征的分布格局。非地带性因素主导着植被发生和演替,很难达到上海以亚热带常绿阔叶林为主的地带性植被类型。

Based on detailed community study on the natural vegetation of Jiangwan Airport abandoned 17 years ago, floristic composition and structure character of the communities have been analyzed, in addition, the restoration process and potential of the communities were also illuminated. The results indicated that the vegetation could be classified as 4 physiognomy types and 16 community types. Herbage communities were the main part of the natural vegetation. The develop-ment and succession of the vegetation were determined by the azonal factors, so it was difficult for the vegetation to develop to zonai vegetation dominated by subtropical evergreen broad-leave forest.
