摘　　要：研究了黑龙江东部山区森林生态系统的物种组成和生物多样性.调查结果表明:森林植物群落物种丰富度指数和多样性指数大小依次为:草本层>乔木层>灌木层;森林昆虫群落的物种多样性指数大小依次为:植食性昆虫>捕食性昆虫>寄生性昆虫,群落均匀度的变化不明显.Authors investigated the species composition and biodiversity of forest ecosystems in Eastem Mountain Area of Heilongjiang Province. The biodiversities of forest plant communities at various sample plots were different. It was maximum at sample plot 1. The diversity and species richness of forest plant communities were： the herbage group ＞ the treegroup ＞the shrub group. The diversity of forest insect communities were： the herbivorous insec group ＞the predatory insect group ＞ the parasitical natural enemy insect goups. The species evenness of forest plant communities and forest insect communities has not change.
