摘　　要：采用聚类分析法,把陕西省内的栓皮栎林划分为6个群丛,分别为:(1)栓皮栎-僵子栎-大披针苔林;(2)栓皮栎-胡枝子+铁仔-大披针苔林;(3)栓皮栎-胡枝子+黄栌-牛尾蒿+大油芒林;(4)栓皮栎-胡枝子+荚蒾-大披针苔林;(5)栓皮栎-黄檀-大披针苔林;(6)栓皮栎-侧柏+黄栌+胡枝子-野青茅+大披针苔林。采用重要值作为多样性测度指标,计算了物种丰富度指数S、多样性Simpson指数、Shannon指数、均匀度Pielou指数和Alatlo指数;探讨了各群丛的物种多样性特征。The study used Cluster Analysis to divide Quercus variabilis forests in Shaanxi Province into six types：Q, variabilis-Q, baronii-Carex lanceolata ; Q. variabilis-Lespedeza bicolor ＋ Myrsinea fricana-C, lanceolata ; Q. variabilis-Lespedeza bicolor ＋ Continus coggy gria-Antemisia subdigitata ＋ Spodiopgon sibiricus Q. variabilis-Lespedeza bicolor ＋Viburnum schensianum-C, lanceolata;Q, variabilis-Dalbergia hupena-C, lan-ceolata ; Q. variabilis-Platycladus orientalis ＋ Continus coggygria ＋ Lespedeza bicolor-Deyeaxia arundinscea ＋C. lanceolata. Using Importance Value as the measuring index of biodiversity, the rich index of species, Simpson and Shannon biodiversity indexes,Pielou and Alatlo evenness indexes were calculated. The biodiversity character of each type was analysed.
