Community Structure and Species Diversity of Semi-humid Evergreen Broad-leaved Forests in Nanhua County of Ailao Mountain Reserve
摘要
Abstract
[Objective]In order to understand the community structure and species diversity of semi-humid evergreen broadforest in Nanhua County,Ailao Mountain Reserve.[Method]The species composition,structure characteristics,species diversity and human activities of plant communities were analyzed based on six fixed monitoring plots in 2021.[Result]The results showed that a total of 81 families,136 genera and 204 species were recorded in this area,and Roseaceae,Fagaceae,Smilacaceae,Camelliaceae,Gramineae,Papilionaceae,Caprifoliaceae,Urticaceae and Camphoraceae were the main families of the community,and Rubus,Smilax and Lithocarpus were the dominant genera.In the tree layer of community,Fagaceae,Theaceae and Bilberry were the main family,and Castanopsis,Conus,Cranberry were the main generas,and Castanopsis orthacantha,Lithocarpus craibianus and Castanopsis delavayi were the dominant species.In the shrub layer,the dominant spe-cies of the community were the Sarcococca wallichii,Rubus ichangensis and Yushania niitakayamensis.The dominant species in the herbaceous layer were Melissa axillaris,Athyrium sinense,Conandron ramondioides,and Polygonum polygonum,while the dominant species in the inter-layer layer were woody liana Smilax septemnervia,Tetrastigma serrulatum var.puberulum and Callerya nitida,few epiphytic ferns.The compos-ite index of the semi-humid evergreen broad-leaved forest community presented herbaceous layer＞tree layer＞shrub layer＞interlayer layer in this area.[Conclusion]The community structure is unstable,and it is also affected by the invasion of alien species and human activities.It is urgent to strengthen the control of human activities and carry out regular monitoring investigations and studies in the Reserve,which is ex-tremely important for the restoration of forest vegetation and biodiversity protection.关键词
