摘  要:
应用丰富度、多样性、均匀度指标 ,研究了北京西山地区 10种人工林群落的物种多样性 .结果表明 :①大多数群落的Shannon Wiener指数H在 1 5~ 3 0之间 ,且与物种丰富度指数的变化趋势一致 ,使用效果比较理想 ;②不同人工林群落中 ,乔木第一亚层的物种丰富度指数和Shannon Wiener指数均低于乔木第二亚层 ,而Simpson指数则相反 ;③不同人工林群落中 ,槲树和华山松林物种丰富度和Shannon Wiener指数较高 ;④草本层的物种丰富度和Shannon Wiener指数高于灌木层和乔木层 ,而乔木层和灌木层没有明显的差异 ;⑤各多样性指数在不同群落间的变化幅度均为草本层 >灌木层 >乔木层 .

摘  要:
Apply richness, species diversity, dominance index to study 10 different plantation communities. The results show that: ①The Shannon\|Wiener index of most plantation communities is 1 5~3 0. Its changing tendencies are identical with the richness. The application effect is good. ②The richness and Shannon\|Wiener index of 1 tree sublayer are lower than 2 tree sublayer, but Simpson index is larger. ③In different plantation communities, the richness and Shannon\|Wiener index of Pinus armandii Franch and Quercus dentata Thunb are richer than others'. ④The richness and Shannon\|Wiener index for different layers in plantation community show that the herb layer is higher than shrub layer and tree layer, while shrub layer and tree layer are similar. ⑤The variation of species diversity index for different strata is in the following order: herb layer>shrub layer>tree layer.
