A study on the procedure to categorize the forest stands quantitatively as well as efficiently was carried out. Properties of the individual trees in the stands in the Research Forest of Okayama University were investigated, from which sixteen structural quantities were produced. The factor analysis with the sixteen variables elucidated that just four factors, the leaf biomass of tree layer as well as lower tree layer, species diversity and forest age, would contribute to the characteristics of the stands.Then the cluster analysis with the four factors was done, which brougth forth three categories of the forest.Other analysis on the characteristics of the sands with the quantification theory III showed that the stands might be classified into three types in relation to the species composition. The combination of the both analyses readily synthesized seven stand categories, of which characteristics were visualized as schematic diagrams with a personal computer.

对林分定量、高效分类的程序进行了研究。对冈山大学研究林林分中各树种的特性进行了调查，从中产生了16个结构量。16个变量的因子分析表明，影响林分特征的因子只有乔木层和下乔木层叶片生物量、物种多样性和林龄4个。然后对这4个因子进行聚类分析，得到了森林的3种类型。利用定量理论III对林分特征的分析表明，根据林分的种类组成，林分可分为三种类型。这两种分析的结合很容易地合成了7个支架类别，这些类别的特征用个人计算机可视化为原理图。
