摘 要 ：利用主成份分析(PCA)和相互平均法(RA)，把辽宁省新宾县三块石林场次生林划分为三个类型：Ⅰ蒙古栎林；Ⅱ胡桃楸-水曲柳林，Ⅲ杂木林。影响这些次生林排序的主导因子是海拔和坡向。Fisher判别分析验证了PCA对该地区次生林分类是正确的，同时还可以利用Y= 0.0383X1+0.0362X2+0.0944X3+0.0133X4+0.1191X5-0.0510X6，预测调查地区的次生林类型。

Abstract:In this paper, b y means of Principal Component Analysis (PCA)and Reciprocal Averaging (RA),3 natural secondary forest types were classified at Sankuaishi forestry farm of sin Bin county in Liaoning province. Ⅰ. Quercus mongolica forest type Ⅱ. Juglans mandshurica-Fraxinus mandshurica forest type Ⅲ. Broad-leaf mixed forest type. The ordination of types significantly were influenced by altitude, aspect.According to Fishes test discriminant analysis, the classificants were recognized as justified. Using discriminat eqation: Y=0.0383X1+0.0362X2 +0.0944X3+0.0133X4+0.1191X5-0.051X6 can be predicted natural secondary forest types.
