Abstract

Since physical and mechanical properties of wood are affected by environmental factors such as soil and climate change, this study investigated relationships between wood quality factors and stand characteristics of Castanopsis cuspidata var. sieboldii forest in the southern region of Korea, including Jeollanam-do Province and Je-ju island. The obtained results found very close relationships between physical and mechanical properties of wood and stand characteristics. The air-dried density and strength performance of woods showed a negative correlation with the diameter at breast height (DBH) while they were positively related to altitude and drainage of the forest site. And wood properties showed variations depending on the region. These results brought a conclusion that wood of Castanopsis cuspidata var. sieboldii in the southern region could be useful forest resources for timber production.

목재의 물리, 역학적 특성은 토양, 기후변화 등의 환경적 인자뿐만 아니라 임분특성에 의해서도 바뀌게 되므로 남부 세 지역의 임분특성이 목재의 재질특성에 미치는 영향과 지역별 물리, 역학적 특성 등을 비교 검토하였다. 전남, 제주도의 구실잣밤나무 임지에 대하여 임분특성과 목재재질특성을 평가 분석하였는데 이들 간에는 대부분 높은 상관관계가 나타났다. 구실잣밤나무의 기건밀도의 물리적 특성과 휨, 압축, 전단강도의 역학적 특성은 임분 특성에서 흉고직경과는 부의 상관관계를 나타내었고 표고, 배수와는 정의 상관관계를 나타내었으며 모든 부분에서 유의성이 나타났다. 또한 물리 역학적 특성에서도 지역별로 차이가 나타났다. 본 연구의 목재 재질특성 분석결과, 남부지역의 구실잣밤나무는 난대 지역의 유용한 산림자원으로 활용할 수 있을 것으로 생각된다.
