摘    要: 以海南岛霸王岭自然保护区1 hm2老龄原始林样地的调查材料为基础,分析了热带山地雨林群落的组成、高度结构、径级结构及有关的树种多样性特征。结果表明:霸王岭热带山地雨林树种较丰富,物种多样性指数较高。树种数和树木的密度都随高度级、径级的增加而呈负指数或负幂函数递减;热带山地雨林不同高度级、不同径级和不同小样方斑块内的树种数都与树木密度呈显著的正相关关系。热带山地雨林经过自然的演替达到老龄顶极群落后,最后进入主林层的只是少部分树种的少数个体。

关 键 词:群落结构  物种多样性  热带雨林  海南岛

Abstract:The species composition, height, diameter class structure and tree species diversity were examined in a 1 hm 2 plot in old growth tropical montane rain forest in Bawangling Nature Reserve of Hainan Island. The tree species richness and diversity indexes were high relative to forests in mainland China. Both the numbers of tree species and tree density decreased as height class or diameter class increased, fitting both negative exponential and negative power equations. There was a significant positive correlation between tree species abundance and tree density for trees of different height classes, different diameter classes and for trees in different quadrats in the tropical montane rain forest. At successional maturity, only a small number of species with a small proportion of individuals could reach the canopy layer in the old growth community.
Keywords:Community structure  Species diversity  Tropical rain forest  Hainan Island
