摘要:

据实地调查统计，香港果洲群岛共有维管束植物140种，隶属于54科115属，其中蕨类植物5科6属6种，裸子植物1科1属1种，被子植物48科108属133种。植被类型主要为常绿阔叶灌丛、南亚热带常绿阔叶林和热带滨海砂生植被。果洲群岛植物区系以热带、亚热带成分占优势。报道了果洲群岛各岛植物种类，并分析了各岛植物物种多样性的特点以及与邻近地区植物多样性的关系，为香港岛屿植物区系的研究提供基本资料。

Abstract:

Based on the investigation of the flora in Ninepin Group of Hong Kong, there were 140 vascular species belonging to 115 genera and 54 families, of which 5 families, 6 genera and 6 species belonged to Pteridophytes, 48 families, 108 genera and 133 species to Angiosperms, only 1 species to Gymnosperms. The Tropical and Subtropical distribution elements were dominant in this flora. The vegetation types included evergreen broad-leaved shrub、lower subtropical evergreen broad-leaved forest and tropical sand vegetation. The checklist of Ninepin Group plants was reported for the first time, and the characteristic of plant diversity in each island was discussed, the floristics characteristics of the Ninepin Group were also compared with the neighbouring regions, all of these provided some basic references for studying on the flora of Hong Kong.
