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 20×20 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.

상수리나무임분을 대상으로 산림지역에서 쉽게 측정이 가능한 임목밀도, 평균 흉고직경, 평균 수고, 흉고 단면적합 등의 임분특성과 낙엽낙지량과의 관계를 조사한 결과 임분 특성은 꽃과 기타물질을 제외하고 낙엽낙지 구성성분과 유의적인 상관관계가 없는 것으로 나타났다. 약 20개월의 조사기간동안 낙엽낙지 구성성분 중 가장 높은 비율을 차지하는 낙엽량의 경우 흉고단면적합과 상관관계가 없는 것으로 나타났고, 임목밀도도 낙엽량에 유의적인 영향을 미치지 않는 것으로 나타났다. 평균 흉고직경의 경우 임목밀도의 영향을 많이 받기때문에 임목밀도의 결과와 유사하며, 평균수고와 낙엽량의 경우도 유의적인 상관관계가 없는 것으로 나타났다. 이는 성숙한 상수리나무임분의 경우 임관이 울폐되어, 여러 가지 임분특성이 낙엽낙지량에 미치는 영향이 크지 않기 때문으로 그 결과 낙엽낙지량의 년 변화도 유의적인 차이가 없는 것으로 나타났다.
