摘　　要：对通道侗族自治县万佛山镇龙底的翅荚木群落及其周边区域进行植物调查研究,发现龙底共有维管植物114种,隶属于56科88属,其中蕨类植物有5科6属6种,裸子植物有1科2属3种,被子植物有50科80属105种。维管植物56科划分为10个分布区类型,88属划分为12个分布区类型和1个变型;科的分布区类型主要为热带分布,属的分布区类型主要为温带分布和热带分布。翅荚木群落可明显划分为乔木层、灌木层、草本层,其中乔木层物种丰富度最高,达22种。乔木层中翅荚木的重要值最大,达到45.8%;翅荚木是群落的建群种,在群落中占有显著优势。翅荚木群落中,草本层的Pielou均匀度指数、Simpson优势度指数、Shannon-Wiener多样性指数均最高。乔木层物种丰富度较高,故Shannon-Wiener多样性指数比灌木层高,但Pielou均匀度指数和Simpson优势度指数比灌木层低。对龙底翅荚木群落特征的研究可为我国翅荚木的保护及引种栽培提供科学参考。Through investigation and research on the community of Zenia insignis and its surrounding areas in Longdi,Wanfoshan Town,Tongdao Dong Autonomous County,it was found that there were 114 species of vascular plants belonging to 88 genera and 56 families.Among them,there were 6 species of ferns belonging to 6 genera and 5 families,3 species of gymnosperms belonging to 2 genera and 1 family,and 105 species of angiosperm belonging to 80 genera and 50 families.56 families of vascular plants were classified into 10 areal-types,mainly tropical elements.88 genera were classified into 12 areal-types and 1 subtype,mainly temperate and tropical elements.The community can be clearly divided into tree layer,shrub layer,and herb layer with the highest species richness in the tree layer,reaching 22 species.In the tree layer,the important value of Zenia insignis was the highest,reaching 45.8%.Zenia insignis was the constructive species of the community,and had a significant advantage in the community.The Pielou evenness index,Simpson dominance index,and Shannon-Wiener diversity index of herb layer were the highest.The species richness of the tree layer was higher,so the Shannon-Wiener diversity index was higher than that of the shrub layer,while the Pielou evenness index and Simpson dominance index were lower than those of the shrub layer.The study on the community characteristics of Zenia insignis in Longdi could provide scientific reference for the protection,introduction and cultivation of Zenia insignis in China.
