| 摘 要： | 运用主分量分析法对霍山东、西两坡的１０５个样方进行了排序。前３个主分量占总信息量的７０％左右。降维效果良好。排序图中，样方间距离抽象地表达了群落间的生态学相关程度。据此将所作样方划分为若干群系，分析了群落随环境梯度变化的规律、观测了群落演替的趋向。从而证明ＰＣＡ法在该区森林群落研究中具有良好的适应性。

| Abstract: | In this paper, the forest community in Huoshan mountain, Shanxi was studied using the method of Principal Component Analysis (PCA) ordination. 105 plots used in the sequencing regularity of the community was analysed with the environmental gradient. It was proved that PCA method was applicable to the study of the aestatisilvaes. |
