摘    要:索罟群岛植被的次生性很强,以常绿灌丛为主,兼有次生性常绿阔叶林、滨海沙生灌草丛及少量半红树植物,其中灌木、草本植物种类丰富。群岛共有维管植物259种,隶属于85科207属,其中本土野生植物70科193属245种,包括2种受国家或地方保护的植物。其植物区系热带性质明显,56.47%的科属于泛热带分布,94.69%的属为热带分布类型,83.40%的种为热带分布,与邻近的广东内伶仃岛植物区系具有较高的相似性。受岛屿面积、海拔、隔离程度及人类活动等因素影响,群岛各岛屿的植物物种多样性各有特点,其中大鸦洲、小鸦洲植物种类最丰富。

关 键 词:香港  索罟群岛  植被  物种多样性

Abstract:It is found that the vegetation of Soko Islands has a strong secondary characteristic and shrublands are the main vegetation type,accompanied by secondary evergreen broad-leaved forests,beach vegetation and a small number of semi-mangroves.Shrubs and herbs both are of high diversity.259 vascular species in 207 genera of 85 families are found,including 245 native wild species.And 2 species are listed to be protected by Chinese government or government of the Hong Kong Special Administrative Region.As an important part of the flora of Hong Kong,the flora there is dominated by tropical elements,with more than 50% families,94.69% genera and 83.40% species distributed in tropical area,and is similar to that of Neilingding Island nearby.However,each island has its own characteristic in vascular plants biodiversity,depending on its area,altitude,degree of isolation and human activities on it,and Tai A Chau and Siu A Chau have the highest biodiversity.
Keywords:Hong Kong  Soko Islands  vegetation  species diversity
