摘　　要：在野外调查基础上,采用TWINSPAN将山西太宽河自然保护区栓皮栎群落分为8个群丛,然后分别用丰富度指数、均匀度指数和物种多样性指数对栓皮栎群落的物种多样性进行研究,并用方差分析对各群落之间多样性指数的差异程度进行分析.结果表明:1)栓皮栎群落的物种丰富度指数主要受灌木层影响,然而不同层次的物种对群落物种多样性的贡献不同;2)由于相似的适应特征、物种相似的生境条件和资源利用方式,因此8个群丛各多样性指数间差异不显著(P>0.05);3)在坡度比较平缓、土层较厚和水分条件较好的生境中,栓皮栎群落具有较高的多样性指数;在干扰较强、贫瘠的生境中,多样性指数则较低.42 plots of Quercus variabilis communities in Taikuanhe Nature Reserve were recorded from the field, moreover, those plots were divided into 8 groups by TWINSPAN according to the principle of vegetation classification. The species diversity of the communities was studied by using species richness indices, evenness indices and species diversity indices, respectively. In addition, the differences among these indices for the communities were studied by ANOVA. The results indicated that..（1） The species richness of Q. variabilis communities was mainly correlated with the shrub layer. However,the contributions of species at different layers to the species diversity of community were not equivalent~ （2） There were not significant differences among the diversity index of the 8 Associations by ANOVA, which because of the similar adaptability, the similar habitat of species, the similar way of resources use. （3） The communities had higher diversity index in the habitats with gentle slope,thick soil or the better condition of water,however,the communities＇s diversity index were lower in the highly disturbed habitats and the poorness habitats.
