对东白山(Dongbaishan,DBS)1 hm2森林样地内胸径≥1 cm的木本植物进行统计,初步分析了样地的区系成分、物种组成、群落结构和α多样性.结果表明:样地内共计木本植物48种,隶属23科36属,总计5 493株,以常绿树种为主,共25种,占总优势度的98.18%,重要值的95.22%,总个体数的96.65% ;群落内有明显的优势种、偶见种和部分稀有种,木荷(Schima superba)和马尾松(Pinus massoniana)占显著优势;偶见种和稀有种分别占总物种数的35.42%和20.83%;群落区系类型温带成分相对较多,属级水平温带分布占总属数的52.77%,热带分布占44.44%;群落的垂直结构由林冠层(18种)、亚乔木层(27种)和灌木层(41种)组成.群落中物种相对丰富,物种多样性由高到低整体表现为:灌木层>亚乔木层>林冠层.样地内木本植物物种总径级分布整体呈倒“J”形,群落总体更新良好,但马尾松幼苗储存不足,预示群落将由木荷-马尾松林向木荷林演替,发展为典型的常绿阔叶林.
