摘要: 在中国东北大兴安岭植物区、小兴安岭植物区及交错区,选择典型群落,采用物种丰富度指数、Simpson指数、Shannon-Wiener指数及均匀度指数,研究了大兴安岭植物区、小兴安岭植物区及交错区物种构成和不同分布区群落的结构。分析比较了3个植物区物种多样性指数及不同生活型物种多样性指数及均匀度指数,结果表明:大、小兴安岭植物区与交错区植物种类过渡性明显,小兴安岭植物区和交错区植物群落结构以落叶松、红松、白桦针阔混交林为主,大兴安岭植物区以兴安落叶松、东北白桦、樟子松为主;大、小兴安岭植物区及交错区物种多样性指数表现为小兴安岭植物区>交错区>大兴安岭植物区;大、小兴安岭植物区及交错区不同生活型物种多样性指数变化为草本层>灌木层>乔木层,乔木层物种多样性指数差异显著,灌木层和草本层差异不显著。

Abstract: Typical plots were established in Daxing’an mountain,Xiaoxing’an mountain,and ecotone of the Notheast of China Plant species composition and vertical structure of different distribution regions were studied in Daxing’an Mountain, Xiaoxing’an Mountain and ecotone using species richness, Simpson diversity index, Shannon-Wiener index and evenness index. Meanwhile, the biodiversity and evenness index of the same community in different regions and different life-forms were compared and analysed.The results indicated:There is significant characteristic of transition between Daxing’an Mountain and Xiaoxing’an Mountain. Theopencedrymion dominates Xiaoxing’an Mountain and ecotone,conifer-conifer forest dominates Daxing’an Mountain;The species diversity indexes of three regions are Xiaoxing’an Mountain>econtone>Daxing’an Mountain;The species diversity of different life-forms in different plant regions are herb layer>shrub layer>tree layer. Species diversity was significant different in tree layer, but not found in shrubs layer and herb layer.

Key words: Daxing&rsquo, an Mountain, Xiaoxing&rsquo, an Mountain, ecotone, species diversity
