摘　　要：运用群落物种多样性分析方法对福建省宁德市支提山突脉青冈天然林的物种数量特征进行了研究,结果表明:群落物种多样性指数和均匀度值均较大,群落结构复杂,物种丰富,群落物种多度分布符合Weibull分布。研究结果为保护该地域森林植被提供了理论依据。The quantitative characteristics of Cyclobalanopsis elevaticostata natural forests in Zhiti mountains were studied by means of community species diversity analysis. The results showed that the value of community species diversity exponential and evenness were all high;the community has a complex structure and abundant species;community species abundance distributed in accord with Weibull distribution. The study provided theoretical foundation for management and protection of Cyclobalanopsis elevaticostata natural forests.
