摘　　要：在雷公山国家级自然保护区内雷公山玉山竹群落布设典型样地7个,采用重要值、α多样性指数和Spearman秩相关检验等方法,分析了雷公山玉山竹群落物种多样性特征及主要种间关系。结果表明:样地中雷公山玉山竹群落共有维管束植物8089株74种,分属41科62属,其中禾本科和菊科是该群落的优势科;雷公山玉山竹群落物种多样性与坡位、灌木林盖度和冠层结构等环境因子密切相关;雷公山玉山竹与十字苔草和沟稃草呈显著负相关。Seven typical sample plots of the Yushania leigongshanensis community in the Leigongshan National Nature Reserve were set up.Using importance value,α diversity index and Spearman rank correlation test to analyze the characteristics of species diversity and the main interspecific relationships.The results showed that in the sample site,there were 8 089 strains and 74 species of vascular plants,belonging to 41 families and 62 genera,among which Poaceae and Asteraceae are the dominant families of the community.The species diversity of the community was closely related to environmental factors such as slope position,shrub coverage and canopy structure.Yushania leigongshanensis showed a significant negative correlation with Simplices tanakana and Aniselytron treutleri.
