ABSTRACT
The purpose of this study was to analyze the relationship between the annual variation in diameter growth of Quercus spp. and climatic factors such as monthly temperature, precipitation and solar radiation in central and northern Korea. Annual diameter growth was measured by using stem cores of 262 Quercus trees, and the correlation between the diameter growth and the climatic factors was analyzed. Mean diameter growth of Quercus spp. in Jungwangsan was larger than that in Woraksan, and mean diameter growth by the species was large in order of Q. serrata>Q. variablis>Q. mongolica>Q. dentata. The diameter growth pattern of Quercus spp. in Woraksan was different from that in Jungwangsan. Positive correlations between diameter growth of Quercus trees and temperature or the solar radiation during July were found in Jungwangsan. Significant correlations between diameter growth and solar radiation during March and precipitation during June were found in Woraksan. It is suggested that climatic factors similarly affect the diameter growth of Quercus spp. in a mountainous terrain, but influences of the climatic factors depend on other environmental conditions such as altitude, topography and soil depth.

적요

우리나라 중북부의 산림에서 참나무류의 연년 직경생장 변화와 온도, 강수량, 일조량 등 기상요인과의 관계를 분석하였다. 연년직경생장은 262개의 참나무에서 채취한 생장편을 이용하여 측정하였다. 참나무류의 연년직경생장은 월악산보다 중왕산에서 더 좋았으며, 종별로는 졸참나무>굴참나무>신갈나무>떡갈나무 순으로 크게 나타났다. 월악산과 중왕산 두 지역간의 참나무류 생장패턴은 서로 달랐으며, 중왕산에서는 참나무류의 직경생장이 7월의 기온이나 일조량과 양의 상관관계가 있는 것으로 나타났다. 그러나 월악산에서는 3월의 일조량과 6월의 강수량이 연륜생장과 유의한 양의 상관이 있는 것으로 나타났다. 같은 지역의 산림내에서 참나무류의 직경생장에 영향을 미치는 기상조건이 같아도 해발고, 지형, 토심과 같은 식생환경에 따라 기상인자의 영향정도가 다른 것으로 추정된다.
