摘 要 ：初步探讨了海南岛坝王岭自然保护区热带山地雨林的代表群落类型即陆均松－线枝蒲桃群系的种 子植物区系组成及其地理分布特点。此群落含有61科、137属、326种，热带分布特别是热带－亚洲 分布的成分占有明显优势，其次是泛热带分布，热带性很强，中国特有分布的种属所占比例极低。 单、寡种属极为丰富是该地区植物区系组成的另一特点。

Abstract:Based on the data investigated in the last decade and the survey of sampling plots of about 10 hm², the floristic composition of formation Dacrydium pierrei/Syzygium araiocladum was studied of tropical montane rain forest in Bawangling Nature Reserve located around the border between Changjiang and Baisha counties on Hainan Island. Three hundred and twenty six species in 137 genera and 61 families are involved. The dominant species and the number of species in main families as well as monotypic and oligotypic species are reviewed．The world distribution pattern of all taxa investigated is described and analysed． It is shown that tropical elements，in particular， tropical Asia elements are the main Ones ，followed by pantropic．Species and genera endemic to China are very limited，but monotypic and oligotypic genera are rich in the flora．
