초록

본 연구는 전남 완도 붉가시나무림의 솎아베기 강도 처리에 따른 임분의 생장반응 특성을 비교 분석하였다. 1999년 솎아베기 후 연년 직경 생장량과 연년 재적 생장량에서 강도구의 효과가 가장 큰 것으로 나타났고, 약도구 또한 비슷한 수준의 효과가 있었다. H/D율은 DBH 생장량의 증가로 인해 약 80%까지 임목 형질 개선효과가 나타났다. 솎아베기 이후 강도구와 약도구의 임분 흉고단면적 총 생장량이 증가하는 경향으로 나타났으나, 간벌구의 손실로 말미암아 임분 흉고단면적은 대조구의 생장량 수준까지 장차 회복하기는 어려울 것으로 예측되었다.

This study was examined for the growth response of tree diameter and volume to thinning treatments from different thinning intensities using three long-term thinning trials for Japanese Evergreen Oak (Quercus acuta Thunb.) stands in Wando island, Korea. After thinning in 1999, annual tree growth of diameter and volume was highest in heavy thinned stands for individual tree and this growth pattern of thinning response showed similar tendency to the individual tree growth response in light thinned stands. By increasing diameter growth, the value of H/D ratio (HDR) as an indicator of stem form was properly decreased and improved up to 80%. Although there is significant growth response of basal area in both heavily and lightly thinned stands, the growth potential both of heavily and lightly thinned stands in total stand volume is not likely to reach at the level of unthinned stands because of basal area growth loss associated with both light and heavy thinnings.
