This report aims to clarify the stand composition of larch forests in Kyushu District and to obtain a guide for their management in the future. And the present reports is on the results of the investigations carried out at Mt. Kuju, Mt. Ryoshi, Mt. Waita, Mt. Heike and Mt, Sobo in the Mori, Takeda and Takachiho working units of the national forest. The results are summarized as follows: 1. The results of the stem analysis are given in Tables 3 and 4. 2. The regression equation between the volume (y) by stem analysis and the volume (x) by "Hokkaido Standing Volume Table" is y = 0.0005 + 0.9709x and there is no significant difference observed. 3. The stand composition is as shown in Table 5and Figs. 3 and 4. 4. The results of comparison with larch forests in Shinshu District are shown in Figs. 5-12. Judging from the above results, the peculiarities of larch forests in Kyushu District are as follows: 1. The stand density is dense. 2. The growth in d. b. h. is good, but the growth in tree height is bad. 3. The trees are of tapering tree form. 4. The"Hokkaido Standing Volume Tabe"is very well applicable to the stem volume in Kyushu. 5. They are susceptible to typhoon damages.I 緒言　II 九州におけるカラマツ林の概況　III 調査結果　IV 信州カラマツ林との比較　V 考察　VI　総括　Resume
