摘　　要：文章以物种丰富度、多样性指数、均匀度指数和盖度为主要指标,探讨了人为干预措施对典型森林群落蒙古栎次生林物种组成和多样性的影响。结果表明:灌木层丰富度变化不明显,其他指数均有所增加,多样性指数样地I、II较高,Pielou均匀度指数样地III、IV较高。草本层丰富度、多样性指数、盖度均有所增加,样地I、II变化最为明显,Pielou均匀度指数样地III、IV增长较大。林下更新数量均有提高,样地I的提升量达7.5%,其次为样地II,具体表现为:样地I>II>III>IV>CK。各样地的更新树种种类相差不大,均以蒙古栎、山杏为主。In this paper,the effects of human intervention measures on the species composition and diversity of the secondary forest of Quercus mongolica were studied using species richness,diversity index,evenness index and coverage as the main indexes.The re‐sults showed that the richness of shrub layer did not change significantly,and other indices increased,the diversity index plots I and II were higher,and the evenness index plots III and IV were higher.The richness,diversity index and coverage of herbaceous layer increased,and the changes were most obvious in plots I and II,while the evenness index of Pielou plot III and IV increased signifi‐cantly.The amount of understory regeneration increased,and the increase of plot I was 7.5%,followed by plot II,which was as fol‐lows:plot I>II>III>IV>CK.There was little difference in species of regeneration trees in different places,mainly Quercus mon‐golica and Armeniaca sibirica.
