摘　　要：在安溪云中山自然保护区南岭栲天然林群落中设置样地调查,根据Raunkiaer系统基分类标准,对南岭栲天然林群落的植物生活型、叶特征及植物耐荫性进行分析,结果表明南岭栲群落中高位芽植物为主,又以小高位芽植物优势显著,占47.8%;叶级以中型叶植物为主,占59.4%;叶型以单叶为主,占78.3%;厚革质与革质叶植物共占群落的72.5%,纸质叶占24.6%,薄叶为2.6%;全缘植物在群落中稍具优势,占53.6%;群落中耐荫植物占多,但以阳性植物为群落演替的主导。Through the plots investigation in the Castanopsisfordii Hance nature forests in Anxi Yunzhongshan Nature Reserve, the plant life-form and leaf characteristics of 69 plants in Castanopsisfordii Hance community in Yunzhong Mountain in Fujian Province were analyzed according to Raunkiaer system. Phanerophytes occupied a dominant position in the community, microphanerophytes had the highest percentage, whose percentage was 47.8% ; The dominant leaf size was mesophyll whose percentage was 59.4% ; Simple leaves were dominant in leaf form and the percentage of those was 78.3% ; The dominant leaf characters were thick coriaceous and coriaceous leaves （72.5%）, followed by papery leaves （24.6%）, thin leaves （2.6%） ;The leaf edges of 69 plants were investigated and the percentage of entire leaf plants was 53.6%. The community had the highest proportion of shade-tolerant plants, but the heliophilous plants for the dominant of community succession.
