| Description | In forest, inventories and management plans, the estimation of stand volume growth is an important problem, and we must pay principal attention to the estimation of the volume growth of stand.
In this paper, we compared with 3 methods ─ HIRATA's, PRESSLER's and every tree survey method ─ in the accuracy of measurment by the increment borer at the stand of Akamatsu（Pinus densiflora Sieb. et Zucc.) The results of the experiments are summarized, in Tables 1 - 4. Using the increment borer, HIRATA's method is the easiest and accuratest way. The results of this study are applied for the Akamatsu stand in eastern part of Shimane prefectur. The growth percenage in volume is about 5% in this stand. |
