Ma-ate forest stands by selection method have been managed by forest owners self-will in the private forest, Wazima city, Isikawa prefecture, and the individual and peculier works for cutting, harvesting, planting and other regeneration made the various stand types. We selected 3 plots (Table 1) among them, cut 20-25 trees in each plot and calculated the diameter the dimension of sigle stem volume by the stem-analysis. Comparing with the accuracy for the adaptation of various stem volume formulas, we got the most accurate and convenient one, and it is as follows :
Konosu V = 0.00188 + 0.00004032 (D^2H) Yamamoto V = 0.00495 + 0.00004419 (D^2H) Futamata V = 0.00432 + 0.00003984 (D^2H) The standard error of estimate based on these formulas is 2.6, 7.0, and 4.2% respectively. |
