内容記述(抄録等)
The selection forests of Ate were investigated on the stand structure, and eight permanent plots had been set up at Wajima City in 1967-68. This paper deals with the change of stand structure and volume increment of these plots in the first cutting cycle(ten years).
The diameter distribution of these plots is shown as Meyer's formula(y=ke^<-α・x>) and k is relate to α as following equation.
k = -108.6+8286・α
The current annual volume increments per ha of Konosu, Yamamoto, Futamata, Kaifuku, Ishiyasumiba, Koizumi and Hosoya (B), (C) Plots were 14.0, 11.5, 14.5, 11.7, 18.0, 19.6, 11.0 and 13.1m^3 respectively. This range (11.5~19.6m^3) of volume increment is greater than the maximum value of mean volume increment(8m^3) of Ate yield table.
Konosu plot was youngest in age, lowest in stand density, and fairly understocked among the eight plots, and current annual increment in diameter and height of lower storied trees is very vigorous.
