摘　　要：在 1hm2 样地调查材料的基础上 ,分析了福建三明格氏栲自然保护区森林群落的种类组成、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 1 1 0种 ,隶属于 42科 6 8属 ,其中单种属占 6 7% ,包括藤本在内的高位芽植物占总数的 87 3%。除格氏栲种群符合随机分布外 ,其它乔木种群均服从聚集分布 ,在垂直空间上可分为 3个亚层。Based on the data collected from sample plots with an area of 10000m\+2, the species composition, physiognomy, and spatial structure of \%Castanopsis kawakamii\% community in Sanming, Fujian, were analysed. The community is composed of 110 vascular plant species belonging to 42 families and 68 genera, 67.6 percent of genera contain only single species. The spatial patterns of dominant tree populations, except \%Castanopsis kawakamii\% which exhibits random dispersion, conform to aggregated distribution. The tree layer can be divided into 3 sublayers in terms of height. The comparative analyses on life form spectrum, 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.
