摘　　要：物种多样性是描述森林群落结构及个体组成的一个重要指标。采用Margalef丰富度指数、ShannonWiener多样性指数、Simpson多样性指数、Pielou均匀度指数等几个主要参数对辽宁东部山区柞树林不同间伐强度下植物种类多样性规律进行了研究。结果表明,随着柞树林间伐强度的递增,群落的多样性呈递减的趋势。The description of the species diversity is an important indicator of forest community structure and com‐position of the individual .Diversity law of plant of Xylosma racemosum in eastern mountains of Liaoning Province under different thinning intensities was studied by using different parameters (the Margalef richness index ,Shannon‐Wiener diversity index ,Simpson diversity index ,Pielou evenness index) .Result shows that diversity of communities shows a decreasing trend with the increase of thinning intensity for Xylosma racemosum .
