Abstract

Wood properties depend on not only environmental factors such as soil, climate change, or forest stand characteristics, but also silviculture practices such as thinning, regeneration, or selection. This study report influences of the extent of thinning intensity from no thinning, moderate and heavy thinning to the wood property of Quercus acuta forest stands in Wan-do arboretum, Jeollanam-do Province. The results showed that there were close relationships between thinning intensity and anatomical, physical or mechanical properties of Quercus acuta wood. Especially, there are close relationships between thinning intensity and ring width or mechanical properties of wood. As a result, this study showed high correlations between Quercus acuta wood properties and thinning intensity of Quercus acuta forest stand. These findings are expected to be very useful as fundamental data for the implementation of silviculture practices of this specie to produce timber.

목재의 재질특성은 토양, 기후, 임분특성 등의 환경적 요인뿐만 아니라 인위적인 처리에 의해서도 바뀌게 되므로 남부지역의 전라남도 완도 수목원에서 무간벌, 약도간벌, 강도간벌의 간벌강도에 따른 목재의 조직 물리 역학적 특성을 평가 분석한 결과 간벌 강도에 따라 여러 조건에서 높은 상관관계를 나타내었다. 특히 간벌강도는 연륜폭과 역학적 특성에서 밀접한 상관관계를 나타내었다. 본 연구결과 붉가시나무의 간벌강도와 재질특성 사이에서 상관관계가 나타났고 이러한 결과는 목재를 시업체계와 육림방법 시스템에 적용할 수 있는 기초자료로서 활용가치가 높을 것으로 판단된다.
