| 内容記述（抄録等） | Following the previous report, authors have investigated the stand structure of other 3 plot of Maate selection forests in Wajima city, Ishikawa prefecture, in 1968. The results are as follows :
1. Adding data of 3 plots of the first report, the relation between number of trees and D.b.h. is shown as MEYER's formula(y = k・e^<α・x>), and k is relate to α as following equation. k = -5.82 ＋ 804.6・α 2. Among operations of selection forests, prunning is comparatively important one, and the relation of clear length to D.b.h. is given as NASLUND formula. 3. The range of current annual volume increment among 6 plots is 10.2～15.9m^3. 4. Maate yield table has been prepared since 1969, and maximum value of mean annual volume increment is 7.8m^3 in this table. It seems likely that annual volume increment of selection forest is greater than that of yield table. |
