摘要
运用伽玛分布、对数正态分布、韦布 (Weibull)分布、正态分布等 4种概率分布模型对格氏栲林的乔木层、灌木层、藤本层、草本层的物种 -多度关系进行拟合分析 ,并用多种物种多样性指标测定格氏栲林各层次数量特征 .结果表明 :格氏栲林群落各层次物种 -多度关系均符合伽玛分布 ,即伽玛分布模型应用于格氏栲林物种 -多度分布研究是理想的 ;格氏栲林物种多样性指标介于中亚热带常绿阔叶林与南亚热带季风常绿阔叶林之间 .表 5参 2
Four models including Г distribution,log-normal distribution,Weibull distribution and normal distribution were used to simulate the species abundance distribution of arbor layer,shrub layer,vine layer and herb layer of Castanopsis kawakamii forest.The quantitative characteristics for each layer in C. kawakamii forest was measured by means of various species diversity indices.The results show that the species diversity distribution of each layer in C. kawakamii forest follows Г distribution.The species diversity of the community measured by means of species diversity indices indicates that the forest of C.kawakamii is a transitional type from south-subtropical evergreen broad-leaved forest to mid-subtropical evergreen broad-leaved forest.This study provides theoretical basis for management and protection of C.kawakamii forest.Tab 5, Ref 20
