摘要
本文在０．３公顷样地调查材料的基础上，分析了福建三明小湖地区格氏栲群落的植物区系成份、群落外貌、水平结构和垂直结构特征．该群落共有维管束植物１１０种，隶属于４２科６８属，其中单种属占６７．６％，包括藤本在内的高位芽植物占总数的８７．３％．乔木种群的空间格局以聚集分布为主，在垂直空间上常可分为三个亚层．物种多样性指数介于南亚热带季风常绿阔叶林和中亚热带常绿阔叶林之间．
Based on the data collected from sample plots with an area of 3000m2,the floristic composition,physiognomy,and spatial structure of Castanopsis kawakamii community in Sanming,China,were analysed.The community is composed of 110 vascular plant species which fall into 42 families and 68 genera,67.6 percent of which are single-species genera.The spatial patterns of dominant tree populations except Castanopsis kawakamii comform to aggregated distribution.The tree layer can be divided into 3 sublayers in terms of height.The comparative analyses on life form spectum,leaf characters and species diversity of the community showed that this forest is a transitional type from south-subtropical rain forest to mid-subtropical evergreen broad-leaved forest.
