摘　　要：研究浙江古田山自然保护区青冈群落特征和物种多样性结果表明,青冈群落植物种类丰富,区系成分复杂,其属的地理成分具有较高的热带成分比例。群落生活型以高位芽植物为主,叶性质以小型叶、单叶、革质和非全缘为主。群落垂直结构中灌木层→乔木层→草本层物种多样性依次递减,乔木层、灌木层物种丰富度和物种多样性指数明显大于草本层。The features and special diversity of the Cyclobalanopsis glauca community in Gutian Mountain Nature Reserve Zone of Zhejiang Province were analyzed.The results show that there are various plants in the community of Cyclo-(balanopsis) glauca,and their floral compositions are complicated.In terms of genus geographical elements,many of them are distributed in tropical zones.According to Raunkiaer's statistics of life-form,the life-form phaenerophyte of this community numbers first.The features of the community leaf is mainly microphyll,simple,leathery and unentire.The special diversity index of different layers shows that shrub layer>tree layer>herb layer,and the special abundance and diversity index of shrub layer and tree layer are higher significantly than those of herb layer.
