The Characteristics and Distribution of Main Vegetationand Community Types in Neilingding Island

广东省内伶仃岛位于珠江口伶仃洋的东部，属南亚热带季风气候区，其自然植被的主要类型有：南亚热带常绿针叶林、南亚热带针阔叶混交林、南亚热带常绿阔叶林、南亚热带红树林、南亚热带竹林、南亚热带常绿灌丛、南亚热带灌草丛、滨海砂生灌草丛等，包括８个植被亚型、１８个群系。人工植被主要有台湾相思林等４个群系，以及果园林４类、作物园４类。地带性植被为南亚热带常绿阔叶林；优势植被类型为台湾相思林、马尾松林，两者的建群种均为衰退种群，已形成多个发育阶段。论文对各主要植被类型及群落结构特征进行分析。

The Neiliingding is located in the east Lingding Ocean at the estuary of Pearl River inGuangdong Province, which belongs to the area of south subtrpical monsoon climate. The main typesof nature vegetation in Neilingding was included 5 vegetation types, 8 vegetation sub-types, and18 formations. The artificial forests were mainly included Acacia confusa forest (4 formations), fruitgarden and crop garden, etc. The typical vegetation or zonal vegetation used to be covered by the lowersubtropical ever-green forest. But the dominant types in Neilingding Island were characterized by Acacia Confusa, Pinus massoniana popolation, which both were formed the different development stages.Meanwhile, the characteristics of main vegetation types and their community structure were investigatedand described.
