摘　　要：采用样地法,研究了南岳栓皮栎Quercus variabilis群落的种类组成、外貌、结构特征及物种多样性。结果表明:在1 500m2样地中,共有维管束植物62种,分属35科54属,其中优势科主要有壳斗科、菊科和蔷薇科等;该群落是以栓皮栎为主的单优种群落,生活型谱以高位芽植物最多,群落季相明显;群落分层明显,可划分为乔木层、灌木层、草本层和层间植物;灌木层植物种类相对较丰富,对群落物种多样性具有较大影响,物种多样性的大小顺序依次为灌木层>藤本层>草本层>乔木层。The characteristics and species diversity of Quercus variabilis community were studied based on community investigation.The results show that 62 species in 54 genera and 35 families of vascular plants were recorded in 15 plots of l 500 m2,in which the dominant families are Fagaceae,Compositae and Rosaceae.Phanerophytes are the largest in number of all species in the community according to Raukiaer＇s statistics of life form.The aspection of the forest community is distinct all the year round.The layered phenomena is very obvious of Quercus variabilis community which can be divided into arborous layer,shrub layer,herbaceous layer and liana,and Quercus variabilis is the only dominant species of the community.The shrub layer is relatively abundant in species and has a greater effect on the community diversity.The diversity pattern from high to low diversity index is shrub,liana,herb and arbor.
