종가시나무 임분의 솎아베기에 따른 흉고직경 및 재적생장 모니터링

This study was conducted to investigate the changes in diameter and volume increment according to thinning treatments of the Quercus glauca stands. The thinning treatments were treated with light and heavy based on volume. Increment changes were compared between the thinning treatments and control group. Seven years later, the diameter of breast height in heavy thinning treatment was significantly different in the DBH increment compared to the control group. The periodic annual increment of the heavy treatment was also different from that of the control group, and the change of diameter increment of the light thinning treatment was not statistically significant when compared with the control group. The volume increment change after 7 years did not show significant difference in treatment groups. And the periodic annual increment of the heavy thinning treatment was numerically high, but there was no significant difference statistically. In conclusion, the increment change by the thinning treatments of the Quercus glauca stands was changed in the diameter of the heavy thinning treatment according to the expansion of the growth space of the standing trees. However, volume increment did not show significant difference by thinning treatments according to the decrease of number of standing trees.
