The purpose of this study is to make clear quantitatively the appearance frequency and the occupation rate of each species which constructs the stand. It is recognized that 1. The standing crop is not influenced by topographic factors. 2. The occupation rates of Picea jezoensis Carr.and Quercus mongolica Turcz.increase on gentle slopes, the rates of Betula maximowicziana Regel and Tilia japonica Simk.increase on steep slopes. 3. The occupation rates of Abies sachalinensis Mast.and Picea glehnii Mast.increase on slopes facing south.the rates of Cercidiphyllum japoicum S.et Z.and Acer mono Max.var.glabrum Hara increase on slopes facing north. 4. The number of surviving trees increase on steep slopes and on slopes facing south.

本研究的目的是定量地了解构成林分的各个树种的出现频率和占有率。认为1.现存量不受地形因素的影响。2.在缓坡上，云杉和蒙古栎林的占有率增加，在陡坡上，极大白桦和苦丁树的占有率增加。3.向南坡面冷杉和油松的占有率增加，向北坡面的大叶树和光肩枫的占有率增加。4.在陡坡和朝南的斜坡上，存活的树木数量增加。
