摘  要:
采用典型样地法对尤溪棋盘顶钩栲天然林群落进行了研究,结果表明:以钩栲为优势建群种的天然林群落内共有维管束植物60科91属107种;群落有乔木层、灌木层、草本层及一定数量的层间植物,乔木层优势明显,而灌木和草本层发育相对弱;群落多样性指数、丰富度指数均是灌木层>草本层>乔木层,而优势度指数为乔木层>灌木层>草本层;钩栲种群年龄结构类型表现为衰退种群。

摘  要:
Based on typical sample plots,the article studies the natural community of Castanopsis tibetana in Youxi Qipanding.The results show that there are 107 vascular plants,belonging to 60 families and 91 genera,structure natural community depending on the advantage of Castanopsis tibetana.There could be divided into tree layer,namely tree layer,shrub layer and herb layer,and it also has some interlayer plants.Tree layer has obvious superiority,but the shrub layer and herb layer are relatively weak.The community diversity index and richness index all show the order of shrub layer>herbaceous layer>tree layer,while the Simpson index shows the order of tree layer>shrub layer>herbaceous layer.The age structure of Castanopsis tibetana population is regarded as the representation of declining population.
