摘　　要：群落物种多样性反映了生物群落在组成、结构、功能和动态方面的异质性,是生态学研究中十分重要的内容（兰思仁,2003;Ricklefs,2004;井学辉等,2010）。大别山位于安徽、湖北和河南3省交界处,是长江和淮河的天然分水岭,其地带性植被属由亚热带常绿阔叶林向暖温带落叶阔叶林过渡类型（谢中稳等，1995）。多枝尖山区是大别山腹地主峰分水岭的主段，是大别山的第三高峰，最高海拔1721．5m。A survey on vegetation diversity was conducted in 25 plots in Duozhijian region of Dabieshan Mountain. The collected data were analyzed with TWINSPAN software,and nine community types were categorized out of the 25 plots. Shannon index did not fit to vegetation diversity in this area. Simpson index and Pielou eveness were the highest in arbor layer and the lowest in herb layer. Species richness was higher in broad - leaved forests than coniferous forests. The results also demonstrated the species composition and distribution of shrub and herb layers were affected by arbor layer.
