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)栓皮栎一僵子栎一大披针苔林;(2)栓皮栎一胡枝子+铁仔一大披针苔林;(3)栓皮栎一胡枝子+黄栌一牛尾蒿+大油芒林;(4)栓皮栎一胡枝子+荚蓬一大披针苔林;(5)栓皮栎一黄檀一大披针苔林;(6)栓皮栎一侧柏+黄栌+胡枝子一野青茅+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。 |

摘 要(英文):The study used Cluster Analysis tO divide Quercu$variabilis forests in Shaanxi Province into six typest Q.variabilis-Q.baronii-Carex lanceolata;Q.variabilis-Lespedeza bicolor+Myrsinea fricana-C.1an-
ceolata;Q.variabilis-Lespedeza bicolor+Continus coggygria-Antemisia subdigitata+ Spodiopgon sibiricus;Q.variabilis-Lespedeza bicolor+Viburnum schensianum—C.1anceolata;Q.variabilis-Dalbergia hupena-C.1an-ceolata;Q.variabilis-Platycladus orientalis+Continus coggygria+ Lespedeza bicolor—Deyeaxia arundinscea+ C.1anceolata. 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 biodiver—
sity character of each type was analysed. |
