| 摘 要： | 植物群落是植物与环境相互作用的产物,探讨森林群落的分布格局、多样性变化规律及其与环境因子的关系,有助于该区森林群落稳定性的维持和生物多样性保护。在东北阔叶红松林区,沿纬度梯度在典型区域选择未受干扰的原始阔叶红松林进行群落调查,并运用多元回归树(MRT)、物种多样性指数比较和典范对应分析(CCA)方法,对森林群落进行分类、比较和排序。结果表明:东北阔叶红松林森林群落可分为4个类型,不同群落类型间物种组成及多样性差异显著。物种丰富度及多样性指数均为低纬度区的千金榆-枫桦-红松林显著高于高纬度地区的冷杉-红松林群落。CCA排序结果较好地反映了各群落类型的分布范围及其与环境因子的关系,其变化格局主要受温度和降水的影响,其次是土壤养分。该结果为气候变化下阔叶红松林的管理和保护提供了相应的理论依据。
