摘　　要：本文通过对土地类型与自然区划关系的分析,提出土地类型结构分析的新方法和自然区划指标,用聚类分析原理与方法对自然区划的方法进行了探讨。In this paper, the relation between comprehensive physical regionalization and land type is discussed. It is pointed out that land type is the basis of physical regionalization from lower to upper level, and it can make the delimitation more accurate, landscape comparison structure, spatial arranging atructure and temporal succession structure of land type as well as the basic principles of physical regionalization are analysed for exploring the law of the origin and development of the natural evironment and areal differentiation. A quantitative method of physical regionalization from lower to upper level, namely the cluster analysis technique, is suggested and the authors consider that it surely can greatly increase the objectivity in physical regionalization as less affected by man—made factors.
