상수리나무임분의 낙엽낙지량과 임분특성의 관계

Abstract

This study was carried out to evaluate the relationships between stand attributes and litterfall amounts in a 28-year old Quercus acutissima stand. Eighteen sampling plots of 20m×20m were chosen and litterfall was collected from May 2005 to December 2006. There was no correlation between stand attributes (tree density, mean diameter at breast height, mean height, basal area) and litterfall amounts except for flower and miscellaneous litter for the study period. There were no significant relationships between leaf litter and basal area (r=0.02, 0.05; P=0.93, 0.83) and between leaf litter and tree density (r = −0.10, 0.05; P=0.85, 0.69). Also, leaf litter was affected neither by mean diameter at breast height (r = −0.08, 0.30; P=0.73, 0.22) nor by mean height (r = −0.24, 0.09; P=0.34, 0.70). Other litter amounts such as bark, branch, and acorn showed no relationships with the stand attributes (P>0.05). The lack of significant relationships between litterfall amounts and stand attributes could be due to the closed canopy with a complete crown cover in this mature oak stand.
