Community Structure and Species Diversity in the Middle-Elevation Evergreen Broad-Leaved Forest of Ailao Mountains
摘要
Abstract
To protect the montane moist evergreen broad-leaved forest in the area of Shuangbai Coun-ty of Ailao Mountain Reserve on a scientific basis,13fixed plots were established within the jurisdic-tion for monitoring and investigation.The species composition,community structure and species di-versity of plant communities in the plots were analyzed.The results indicated that 259 species of vas-cular plants from 154 genera and 88 families were recorded in the plots of the montane moist evergreen broad-leaved forest community in Shuangbai County.The primary families composing the communi-ty include Rosaceae,Lauraceae,Theaceae,Liliaceae,Ericaceae and Fagaceae.The main genera con-stituting the community were Rubus spp.,Ilex spp.,Smilax spp.,Rhododendron spp.,Litho-carpus crassifolius,L.hancei,Schima noronhae,Castanopsis rufescens were the dominant species and constructive species in the arbor layer.In the shrub layer,the dominant species was Fargesia wu-liangshanensis.In the herbaceous layer,the dominant species were the Cyathula prostrata,Carex praelonga and Carex brachyathera.The interlayer dominant species were Tetrastigma serrulatum var.puberulum,Heterosmilax chinensis and Euonymus fortunei,and mainly woody lianas.The spe-cies diversity index of each layer in the community in order:herbaceous layer＞tree layer＞interlayer＞shrub layer.The structure of the montane moist evergreen broad-leaved forest community in this area was stable.There are a lot of relict plants,which had high value of protection and scientific re-search.关键词
