摘 要：
应用丰富度指数、Shannon-wiener指数、Simpson优势度指数和Pielou均匀度指数对宽坝林区3种人工林群落———黄檗人工林、日本落叶松人工林、柳杉—杉木人工林的植物物种多样性进行了研究,结果表明:黄檗人工林乔木层具有较低的丰富度和多样性,而灌、草层具有较高的丰富度和多样性;柳杉杉木人工林乔木层具有较高的丰富度和多样性以及较低的优势度,而灌、草层内具有较低的丰富度和多样性以及较高的优势度;日本落叶松人工林各层次物种丰富度居中;不同层次间物种多样性有一定的差异,且乔、灌层之间多样性指数和优势度指数的差异均达到显著水平。

摘 要：
Richness,species diversity,dominance and evenness indices were applied to studying the three different plantation communities—Phellodendron amurense plantation,Larix kaempferi plantation and Cryptomeria fortunei-Cunninghamia lanceolata mixed forest community in the Forest Region of Kuanba.The results were as follows: the Phellodendron amurense plantation community had a lower richness and diversity in tree layer,but had a higher richness and diversity in shrub and herb layers;Cryptomeria fortunei-Cunninghamia lanceolata mixed forest community had a higher richness and diversity in tree layer,but had a lower in shrub and herb layers;Larix kaempferi plantation community's richness was in the middle.There was a difference among the different layers in the communities, and the differences of richness and species diversity indices between the tree layer and shrub layer were significant.
