| 摘 要： | 应用物种多样性指数、丰富度指数和均匀度指数等对卧龙自然保护区白泥岗珙桐(Davidia involuarata)群落的物种多样性进行了研究。结果表明，在不同层次之间，群落物种的多样性差异主要表现在乔木层和灌木层，其次是草本层。各层之间物种多样性互相影响较大。在垂直结构上，从上到下，种类数和个体数呈增加之势，而物种多样性在海拔高度1690m～1700m处最高。整个群落具有较高的物种多样性。 |

| Abstract: | The species diversity of Davidia involuarata communities in Wolong Nature Reserve was invesitgated in terms of species diversity indices(Simpson index and Shannon index),species richness index and Pielous'evenness index.The results showed that the species diversity indices were different for different layers.In the communities the tree layer and the shrub layer had relatively high diversity in comparison with the herbaceous layer.Different layers affected each other obviously.The species and quantity of th communities decreased with the increase of elevation.The species diversity was highest at the range of an elevation from 1 690 m to 1 700 m.The species diversity of the whole communities was rich,but the stability was low. |
