摘要: 采用主成分分析法对西藏鲁朗森林立地66个标准地调查实测材料分析,选取海拔高度、坡度、坡向、土层厚度、土壤质地、石砾含量、土壤有机质含量7个因子,共划分出8个森林立地类型.结果表明,在西藏高山峡谷林区以此方法划分森林立地类型较适宜.

Abstract: Through analysing the observed data from 66 standard plots in forest sites of Lulang, Tiber and selecting elevation,slope gradient and its direction, thickness of soil layer, soil texture, graved content and organic matter content as affecting factors, 8 types of forest site are classified with the method of principal component analysis. It is indicated that this method is available to the division of forest site types in mountain-gorge forest regions of Tibet.
