摘　　要：选取白云岩喀斯特山地开展森林植物物种多样性调查分析,采用样地调查方法获取森林植物群落数据,并对群落种类组成、多样性指数进行分析。结果表明:(1)研究区乔木树种以白栎(Quercus fabri)、马尾松(Pinus massoniana)、柏木(Cupressus funebris)、圆柏(Juniperus chinensis)等树种为主,灌木树种以女贞(Ligustrum lucidum)、油茶(Camellia oleifera)、算盘子(Glochidion puberum)占优势,草本植物以蕨(Pteridium aquilinum var.latiusculum)、沿阶草(Ophiopogon bodinieri)等为主。(2)调查群落及其不同层次间的物种多样性存在差异,乔木层树种多样性较低,但均匀度及优势度较高,灌木和草本植物多样性相对较高,但均匀度及优势度却相对较低。研究结果有效促进了白云岩喀斯特山地植被组成及多样性研究,可为白云岩喀斯特山地的生态恢复和治理提供依据。The dolomite karst mountain area was selected to carry out forest plant species diversity survey and analysis,the sample survey method was used to obtain the forest plant community data,and the community species composition and diversity index were analyzed.The results show that:(1)Tree species in the study area are dominated by Quercus fabri,Pinus massoniana,Cupressus funebris,Juniperus chinensis,while dominant shrub species include Ligustrum lucidum,Camellia oleifera,Glochidion puberum.Herbaceous plants are mainly represented by Pteridium aquilinum var.latiusculum and Ophiopogon bodinieri.(2)Species diversity varied among the investigated communities and their different levels,with low diversity of tree species in the tree layer,but high evenness and dominance,and relatively high diversity of shrub species and herbaceous plants,but relatively low evenness and dominance.The results of the study effectively promote the study of vegetation composition and diversity in the dolomite karst mountains,which can provide a basis for the ecological restoration and management of the dolomite Karst areas.
