摘 要:通过野外实地调查以及相关资料的查阅,对香港瓮缸群岛植物种类、特点、分布区类型以及与邻近地区植物多样性的关系进行研究,结果表明,瓮缸群岛共有维管植物166种,隶属于69科138属,其中蕨类植物7科8属10种,裸子植物2科2属2种,被子植物60科128属154种。植物区系以热带性质占优势,具有向亚热带过渡的特点,植被类型以常绿阔叶灌丛、南亚热带灌丛草地为主,其次为南亚热带低山常绿阔叶林和崖壁植被,群岛各岛屿由于岛屿面积、海拔、隔离程度的差异,植物物种多样性各有特点,与邻近的果洲群岛植物区系有较高的相似性,而与蒲台群岛差异较大。Based on investigation and reference consultation,plant species diversity and vegetation of Ung Kong Islands in Hong Kong were studied,including flora composition,characteristics,distribution type,and its relationship with neighboring regions.Results showed that there were 166 vascular plants belonging to 138 genera and 69 families,including 10 species in 8 genera and 7 families of ferns,2 species in 2 genera and 2 families of gymnosperms,and 154 species in 128 genera and 60 families of angiosperms in the Ung Kong Islands.The dominant vegetation types were shrub land and shrub-grass land,while cliff vegetation and evergreen broad-leaved forest were secondary.Each island had its own characteristics in regards to vascular plant biodiversity,as a result of different areas,altitudes and isolation levels.The flora of the Ung Kong Islands show high similarity with Ninepin Group,but much more difference with that of the Po Toi Islands.
