Analysis of Forest Plant Species Diversity in Dolomite Karst Mountains
The dolomite karst mountain area was selected to carry out forest plant species diversity survey and a-nalysis,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 domina-ted by Quercus fabri,Pinus massoniana,Cupressus funebris,Juniperus chinensis,while dominant shrub species in-clude 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 dom-inance,and relatively high diversity of shrub species and herbaceous plants,but relatively low evenness and domi-nance.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.
