摘　　要：采用相邻格子法,对福建安溪油杉天然次生林进行群落调查,分析了该群落的种类组成、群落结构及多样性特征。结果表明:该群落共有维管束植物40科53属73种;乔木层共有树种197株,其中油杉有156株,占总数的79.2%;灌木层和草本层分布有植物38和47种,灌木层中仅发现油杉幼苗11株,草本层中未发现油杉幼苗;综合分析多样性各个指数,可知该油杉群落的乔木层的郁闭度较低,林下植被较丰富,乔木层的多样性等指数均远小于灌木层和草本层。The community characteristics investigation of natural secondary forest of Keleleeria fortune in Anxi County was taken out with contiguous grid quadrat method. The characteristics of K. fortune community, such as kinds, species diversity were studied. Results showed that there were 73 species of vascular plants from 40 families and 53 genera in the community. The sum of K. fortune was 156, which account for 79.2% of the total of the arbor layer. The species m^mber of the shrub layer and herb layer were respectively 38 and 47. Specially, the K.. fortuzze seedling was rarely appeared in the shrub and herb layer. Based on the indexes of species diversity, the shade density of the arbor layer was low, which cause the richness of the understory vegetation.
