Abstract
This paper reports on the dendrochronological investigation of tree ring growth of Pinus densiflora in the Gyeongbuk region. Tree ring growth was analysed using basic statistical value and correlation analysis to evaluate the relative contribution of climatic factors. Ta extract age-related trends and nonclimatic signals, each measurement series was standardized using a negative exponential growth function. In the Gyeongbuk region, tree ring growth was positively correlated with the current year in February, March and April, January, February, and March precipitation showed a positive correlation with the current growth year. This suggests that climatic factors (monthly average temperature, precipitation) limit breaking of dormancy and promotion of growth of Pinus densiflora in the Gyeongbuk region.
본 논문은 경북지역 소나무의 연륜생장에 대하여 연륜생태학적 해석을 통하여 월별 기후인자(월별평균온도, 월별강수량)간의 관계를 기초통계량 및 상관분석을 실시하였다. 실측된 연륜생장곡선은 수령 및 비기후적인 요소를 제거하기 위하여 음지수생장곡선을 이용하여 표준화를 실시하였다. 경북지역 소나무 연륜생장과 기후인자간의 관계에서 당해연도
