摘　　要：2021年,以哀牢山保护区南华县片区4块中山湿性常绿阔叶林群落固定监测样地为基础进行全面调查,并对植物群落物种组成、结构及物种多样性进行分析。结果表明:辖区内中山湿性常绿阔叶林群落调查样地共记录到维管植物82科150属207种,其植物科属组成较为丰富,菊科、蔷薇科等11个科为群落主要组成科。辖区植物群落结构复杂,各层物种组成丰富。变色锥和木果柯为群落乔木层优势种,无量山箭竹、西南绣球为灌木层优势种,黑鳞耳蕨为草本层优势种,毛狭叶崖爬藤、圆锥悬钩子为层间层优势种。层间层植物种类多,以木质藤本为主,附生植物较少。辖区植被群落各层的物种多样性指数总体呈现出草本层的>乔木层的>灌木层的>层间层的。哀牢山保护区需持续开展辖区中山湿性常绿阔叶林综合性监测研究,并提供更好的保护。Based on four fixed monitoring sample plots of mid-montane moist evergreen broadleaf forest communities in Yunan Ailao Mountain Nature Reserve of Nanhua County,the comprehensive survey was conducted in 2021,and the species composition,structure and species diversity of plant community were analyzed.The results showed that a total of 207 species of vascular plants belonging to 150 genera and 82 families were recorded in the survey plots of the moist evergreen broadleaf forest community,and the rich phylogenetic diversity in this region,and 11 families such as Asteraceae and Rosaceae were the main constituent families of the community.The plant community structure within the jurisdiction was complex,and the species richness of each layer was abundant.Castanopsis wattii and Lithocarpus xylocarpus were the dominant species in the arborous layer,Fargesia wuliangshanensis and Hydrangea davidii were the dominant species in the shrub layer,Polystichum makinoi was the dominant species in the herbaceous layer.Tetrastigma serrulatum var.puberulum and Rubus paniculatus were the dominant species in the interlayer.The high species diversity in the interlayer was a significant feature of the community,mainly constituted by woody vines,with few epiphytes.The species diversity index of each layer of the community was generally order:the herbaceous layer>the arborous layer>the shrub layer>the interlayer.The Ailao Mountain Nature Reserve should need to continuously carry out comprehensive monitoring and research on the mid-montane moist evergreen broadleaf forest in its jurisdiction and better protection.
