【摘要】 <正> 本研究主要采用东北林业大学帽儿山场的39块标准地定性和定量因子混合型数据,进行不同的聚类方法分类和图论分类分析,对黑龙江省东部山区的次生林、人工林的燃烧性作初步划分,并对39块标准地构成的样本作一初步的分类。标准地是在各种林地类型、不同立地条件下按典型选择法确定的,基本遍及调查地区的全部范围。每块标准地所采用的9项因子为:有、无林地,坡向,坡位,坡度等立地因子,能反映更多还原

【Abstract】 This article makes hierachical and graphical partition clustering ana-lysis to mixed type (qualitative and quantitative) data of nine items of 39sample plots from secondary growth area.The aim of this study is to clas-sify forest land of various flammabilities. The result shows that the class classified by multivariate statisticalanalysis methods are the similar to forest types and both the clusteringand ordination can be finished at the same time using the graphical me-thod.The interpretation of ordinal relation of various forest land types isgiven.更多还原
