摘要
结合国家森林资源连续清查,对黑河地区不同恢复阶段白桦林的高等植物物种多样性特征进行了初步分析。结果表明:各层物种丰富度和多样性指数在不同恢复阶段各不相同,不同恢复阶段白桦林表现出草本层的物种丰富度和多样性指数>灌木层的物种丰富度和多样性指数>乔木层的物种丰富度和多样性指数的趋势。
This paper analyzes the species diversity characteristics during the different recovery phases of birch forest in Heihe district combined with national forest resource continuously investigation.The result shows that species richness and diversity index are different in different recovery phase.The species richness and diversity index of herbage are larger than that of shrub and tree stratum.
