Abstract

Wood properties are affected by environmental factors such as soil and climate change. There were close relationships between mechanical properties and stand characteristics for Quercus serrata stands in Gyeongsangnam-do Province, Jeollanam-do Province and Je-ju island. Both compression and shear strengths of woods showed a negative correlation with diameter at breast height (DBH) and the number of tree per hector, while they are positively related with with tree age, altitude, and drainage. The annual ring width was also negatively correlated with tree age, altitude, drainage, DBH, and tree height. However, anatomical characteristics of wood did not show much variation depending on the provincial regions. These results brought a conclusion that Quercus serrata in southern region could be useful forest resources for the utilization of wood.

목재의 조직, 물리, 역학적 특성은 토양조건과 기후변화 등의 환경적 인자에 의해서도 바뀌게 됨으로 남부 세 지역의 임분 특성이 목재의 재질특성에 미치는 영향과 지역별 조직, 물리, 역학적 특성 등을 비교 검토하였다. 경상도, 전라도, 제주도의 졸참나무임지에 대해 임분 특성과 목재특성을 평가 분석하였는데 이들 간에는 대부분 높은 상관관계가 나타났다. 남부지역의 졸참나무는 온대에서 난대로 기후가 변화하는 난대 지역의 산림자원으로 본 목재재질특성 분석결과 유용한 산림자원으로 활용할 수 있을 것으로 생각된다.
