Abstract

The effect of relations parameters on the declination gradient of trees was studied in natural forest of Quercus variabilis, Quercus ${\times}$ grosseserrata, Quercus aliens, and Quercus dentata grown at various slope gradient. The declination gradients of trees were effected by the species, slope gradient, and direction of slope, but not effected by density and height in all species. The species shows a superior factor effecting declination gradient of trees compared with other relations parameters, and next effective factor was slope gradient. Especially in all of slope gradient, the declination gradient of Quercus ${\times}$ grossesserrata was highest.

경사면(傾斜面)에 생육(生育)하는 굴참나무, 물참나무, 갈참나무, 떡갈나무 천연림(天然林)의 입목경사도(立木傾斜度)에 미치는 여러 인자(因子)의 영향을 측정(測定) 분석(分析)하였다. 입목경사도(立木傾斜度)에 영향을 미치고 있는 인자(因子)는 수종간(樹種間)의 차(差), 입목경사도(立木傾斜度), 방위(方位)였으며, 입목밀도(立木密度)와 수고(樹高)는 입목경사도(立木傾斜度)와는 상관(相關)이 없었다. 인자(因子) 중 수종간(樹種間)의 차(差)가 입목경사도(立木傾斜度)에 가장 크게 영향을 미쳤으며 다음이 사면경사도(斜面傾斜度)였다. 특히 수종(樹種) 중에서는 물참나무가 모든 사면경사도(斜面傾斜度)에서 가장 기울어지는 양상을 나타내었다.
