采用聚类分析中的离差平方和法和数量化模型 对小兴安岭丰林自然保护区阔叶红松林下的草本植物做了数量分类 ,并结合林分生长量和环境条件分析了聚类结果。其结果表明 ,影响植物分布的主要因子是林分的发育阶段 ,而且林分发育阶段的不同超过了森林类型对林下草本植物的影响。在同一发育阶段 ,由于坡向、坡位、坡度及上层乔木的不同 ,林下草本植物分布又有差异。
Cluster analysis using the method of variance sum of squares and quantitative models of abundance in the small Hinggan Mountains Fenglin Nature Reserve in the Korean pine broad-leaved herbs in the classification, combined with stand growth and environmental conditions analysis of the clustering results. The results showed that the main factor influencing the plant distribution was the development stage of the forest, and the difference in the development stage of the forest exceeded the effect of the forest type on the understory herbaceous plants. In the same developmental stage, the distribution of understory herbaceous plants is different due to the differences of slope, slope position, slope and the upper arbors.
