摘　　要：利用样方法进行野外群落调查,共设计了15个样方,每个样方大小为20 m×5 m,对衡山青冈栎(Cy-clobalanopsis glauca)群落的种类组成、外貌、结构特征及物种多样性进行了研究。结果表明:在1 500 m2样地中,共有维管束植物26科37属46种,其中优势科为壳斗科、山茶科和蔷薇科等;该群落主要是以青冈栎为主的单优种群落,生活型谱以高位芽植物占绝对优势,叶级谱以中、小型叶为优势的特点,群落季相不明显;群落分层较明显,乔木层树种很少,灌木层种类较丰富,对群落物种多样性具有较大影响;物种多样性分析显示该群落多样性指数偏低,其多样性复杂程度由高到低的顺序为灌木层、藤本层、乔木层、草本层。Researching on community species composition, appearance, and structure features and spe- cies diversity of Cyclobalanopsis glauca Oerst. in Hengshan by sampling plot method, There are 15 sam- ples plot, every plot was 20 m × 5 m. The results show that： only in 1 500 m2 plot, totally distribute 26 families, 37 genera and 46 species of vascular plant, extremely Fagaeeae, camellia, and Rosaceae are the dominant families. The community is Cyclobalanopsis glauca Oerst. specie community, with phanero- phytes plants dominated. Middle, small foliage characteristics. Community in season is not obvious, Community stratification is more apparent, the tree layer less species, the shrub layer type is richer, more influence on species diversity of community. The species diversity analysis shows that diversity in- dex is low; the complexity of the diversity from high to low is shrub layer, vine layer, tree layer, herb layer.
