摘要: 为研究云南红豆杉 (Taxus yunnanensis) 群落结构,以云岭省级自然保护区内的云南红豆杉群落为研究对象,基于5个野外群落样方调查数据分析发现:该群落内维管植物共57种,隶属于29科48属。群落分层明显,乔木层、灌木层和草本层的优势种分别为云南红豆杉、箭竹 (Fargesia spathacea) 和蛇莓 (Duchesnea indica);基于物种多样性分析发现,香农-维纳指数、辛普森指数和皮卢均匀度指数均为草本层>乔木层>灌木层;云南红豆杉种群中,幼苗库充足,但幼树缺乏,说明保护区建立对云南红豆杉的保护有积极作用,但仍需加强保护力度,减少人为干扰对云南红豆杉群落的影响。

Abstract:

In order to study the community structure of Taxus yunnanensis the Taxus yunnanensis community in the Yunling Provincial Nature Reserve was taken as the research object. Based on the analysis of the survey data of 5 field community samples it was found that there were 57 species of vascular plants in the community belonging to 29 families and 48 genera. The community stratification is obvious. The dominant species in the tree stratum shrub stratum and herb stratum are Taxus yunnanensis Fargesia spathacea and Duchesnea indica respectively. Based on the analysis of species diversity the Shannon-Wiener index Simpson index and Pielou evenness index is herb stratum> tree stratum> shrub stratum. Taxus yunnanensis has sufficient seedling bank but lacks saplings indicating that the establishment of the reserve has a positive effect on the protection of Taxus yunnanensis but the protection still needs to be strengthened to reduce the impact of human disturbance.

Key words:

"> Taxus yunnanensis, species diversity, age structure, threatened plant
