【摘要】 本文调查和分析了云南高黎贡山自然保护区内天然台湾杉植物群落的物种组成、外貌和结构特征,计测了乔木层的物种多样性。结果表明,该台湾杉群落植物共有48科73属92种植物(不含苔藓、地衣);区系成分较复杂,以温带分布的属为主,北温带成分最多;群落垂直结构明显,分为乔木层、灌木层、草本层;群落的物种多样性指数较高,物种丰富;马蹄荷、台湾杉为优势种,从整个群落看,只有台湾杉三个亚层均有分布,且有更新的幼苗幼树,是以马蹄荷、台湾杉为优势的常绿针阔混交林。更多还原

【Abstract】 In this paper,the species composition,appearance and structural characteristics of natural Taiwania cryptomerioides community in Gaoligong Mountain Nature Reserve of Yunnan Province were investigated and analyzed,and the species diversity of the arbor layer was measured.The results showed that there were 92 species belonging to 73 genera and 48 families in the community (without moss and lichen).The floristic composition of the community was complex,with temperate genera as the dominant species,and the northern temperate zone as the most component.The vertical structure of the community was obvious,which was divided into arbor layer,shrub layer and herbaceous layer.The species diversity index of the community was high and the species were abundant.Horseshoe lotus and Taiwania cryptomerioides flousiana were the dominant species.From the whole community,only Taiwania cryptomerioides were distributed in three sub-layers,and there were also regenerated seedlings and saplings.It was an evergreen coniferous-broad-leaved mixed forest dominated by horseshoe lotus and Taiwania cryptomerioides.更多还原
