This study was conducted to find the age for maximizing stem volume accumulation of major planting tree species, which are Pinus densiflora, Pinus koraiensis and Larix kaempferi, by thinning intensity. For each species, we have developed age-dbh model and dbh-height model by thinning intensity. Also, stand density model was developed by the relationship between quadratic mean diameter and the number of trees. It was assumed that thinning was carried out in 25 and 35 years and that 20% and 40% of the total trees are removed for light thinning and heavy thinning, respectively. The result showed that the difference in diameter growth was clearly caused by thinning intensity in the three species. The diameter difference among the thinning intensities increased more and more as the age increased, while the difference between the light and the heavy was not significant. The stem volume per unit area was non-thinning > light thinning> heavy thinning. Assuming that there was no difference in tree height by thinning intensity, it generally showed a similar trend except that the stem volume was lower than when there was a height difference in thinning intensity.
