摘　　要：为科学保护哀牢山保护区双柏县片区中山湿性常绿阔叶林,在辖区建立13块固定监测样地,对样地内植物群落的物种组成、结构特征及物种多样性进行监测调查和分析,结果表明:样地内记录到维管束植物88科154属259种,蔷薇科、樟科、山茶科、百合科、杜鹃花科、壳斗科为群落主要组成科,悬钩子属、冬青属,菝葜属和杜鹃属为群落主要组成属。硬叶柯、硬壳柯、滇木荷、变色锥为乔木层优势种和建群种;无量山箭竹为灌木层优势种;杯苋、帚状薹草、垂穗薹草为草本层优势种;毛狭叶崖爬藤、华肖菝葜、扶芳藤为层间层优势种,并以木质藤本植物为主。整个植被群落各层物种多样性指数依次为草本层>乔木层>层间层>灌木层。辖区中山湿性常绿阔叶林群落结构稳定,植物种类丰富,保存着大量孑遗植物,具有较高的保护和科研价值。To protect the montane moist evergreen broad-leaved forest in the area of Shuangbai County of Ailao Mountain Reserve on a scientific basis,13fixed plots were established within the jurisdiction for monitoring and investigation.The species composition,community structure and species diversity of plant communities in the plots were analyzed.The results indicated that 259 species of vascular 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 community include Rosaceae,Lauraceae,Theaceae,Liliaceae,Ericaceae and Fagaceae.The main genera constituting the community were Rubus spp.,Ilex spp.,Smilax spp.,Rhododendron spp.,Lithocarpus 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 wuliangshanensis.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 species 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 research.
