内容記述タイプ Abstract
内容記述 1. A method is presented for determining distribution of diameters breast high and predicting growth in natural uneven-aged timber stands, which have not been reached mature forest after cutting or disturbing by natural agencies. 2. The basic data of this treatise have been gathered at a part of the state forest of Kurumijima, Gifu Pref., in summer 1964. 3. The hypotheses, that diameters breast high of stems in natural fir stands distribute in compliance with H. A. MEYER's curve, were accepted in almost sample plots. The formula proposed by H. A. MEYER is represented as follows: y=k・ℯ⁻αx where y is number of stems per hectare in x-th diameter class, x is diameter breast high of stems in cm, k and α are constants. 4. By using H. A. MEYER'S formula, the distribution of diameters breast high in natural fir stands, which have not been reached mature forest after cutting or disturbing by natural agencies, was easily represented. 5. The constants k and a are estimated from average stand diameter breast high or number of stems per hectare. 6. By using distribution table, the growth table was prepared in a form such as yield table. Then site was induced as a function of average stand age and average stand diameter. 7. This growth table can be applied for the prediction of growth to any natural fir stand, which has been reached mature forest after cutting or disturbing by natural agencies, in Kurumijima state forest, Gifu Pref.
