摘　　要：研究贵州荔波茂兰世界自然遗产地的山顶群落演替,为该区植被管理及保护提供科学依据。结果表明:该区不同演替阶段的群落类型。原生林的群落类型为丝栗栲-大芽南蛇藤+猕猴桃-苔草群落;次生林的群落类型为:马尾松-黄棉木+云南鹅耳枥-五节芒群落;灌木林的群落类型为:山矾-苔草群落;草坡的群落类型为:黄茅群落。在不同演替阶段,群落物种相似性都存在一定差异性。相似性系数最高的为62%,发生于灌木林样地之间。相似性系数最低为0,发生于草坡与其它各阶段演替样地中。Studied on the succession of vegetation on upside of mountains at Maolan,Libo county of Guizhou for environmental management and conservation.The results showed that the association of original forest was Castanopsis fargesii-Celastrus gemmatus＋Actinidia chinensis-Carex sp.The association of secondary forest was Pinus massoniana-Carpinus Pubscens-Miscanthus floridulu.The association of bush was Symplocos caudate-Carex sp.The association of pasture was Heteropogon contortus.In different stages of succession,the simulations in different communities had otherness.The highest likeness coefficient was 62% of bushes,and the lowest likeness coefficient was 0 in pasture and other communities.
