摘　　要：通过对黑龙江省东部山区兴安落叶松群落和黄花落叶松群落的调查,分析该地区两种典型落叶松针叶林群落的结构特征和生物多样性特征。结果表明,在垂直层中兴安落叶松林乔木层物种多样性全面优于黄花落叶松林,而灌木层与草本层两群落的物种多样性指标较为接近。β物种多样性中两群落差异系数较大。两种落叶松林种间的生态学的分化比形态学上的差异更为显著。Through investigation of the Larix gmelini community and the Larix olgensis community in the eastern mountainous areas of Heilongjiang Province,the structural and biodiversity characteristics of two typical deciduous coniferous forestcommunities in this area were analyzed.The results showed that the tree layer species diversity of Laria gmelini forest was better than that of Larix olgensis forest in vertical layer,while the species diversity indexes of shrub layer and herb layer were similar.The difference coefficient ofβspecies diversity between the two communities was large,the difference of ecology between the two larch forest species is more significant than the difference of morphology.
