摘要
采用样地调查法对海南霸王岭国家级自然保护区海南粗榧保育群落植被生物多样性进行研究,结果表明,霸王岭的海南粗榧群落生物多样性指数较高,虽然不同样方中的乔木层、灌木草本层的生物多样性指数都表现出极显著差异,但同一样方中乔木层和灌木草本层生物多样性指数相差不大;保育群落中的优势种主要有红紫麻(Oreocnide rubescens)、野芭蕉(Musa wilsonii)、药用狗牙花(Ervatamia officinalis)等;保育区内海南粗榧成年和幼体植株生长情况较好。
Taking the plot investigation method, the biodiversity of Cephalotaxus mannii conservation community in Bawangling National Nature Reserve were analyzed, and the results showed that the biodiversity index of Cephalotaxus mannii community in Bawangling was very high. Although, there were extremely significant differences respectively among the tree stratum＇s and the herbaceous shrub stratum＇s biodiversities in different plots. There was not significant difference between the tree stratum and the herbaceous shrub stratum in a same plot. Oreocnide rubesceus, Musa wilsonii and Ervatamia officinalis were dominant species in the plots. The growth of the adult and the young Cephalotaxus mannii was good.
