다국어 초록 (Multilingual Abstract)

This study was conducted to estimate biomass and sprout growth of Quercus acutissima stands after forest fires in Yesan. The number of stump sprouting was controlled such as 1, 3, 5 sprouts per stump at each plot sites. All of the sprouts per stump measured height, root diameter and DBH during the spring and fall of 2007. According to the results of sprout control study, average diameter values were significant1y larger with lower sprouts per stump. In contrast, average height growth is insensitive to sprout numbers per stump at young Quercus acutissima stands. In the case of sprout biomass production, the results of one sprout per stump sites indicated the largest values ranging from 27. 7kg to 79. 6kg. ‘One variable quadratic model' showed the best results in prediction of stem biomass(B_s= 0.09136 D+0.10525 D²) while ‘Generalized logarithmic model' showed the best in branch and leaf biomass predictions (BB =-0.0173+0.0104 D^2.4458 H^0.7792, B_L =-0.0445+0.0382 D^1.6448 H^0.6224). The results suggested in this study cou1d be very helpfu1 to understand sprout growth pattems and sprout biomass production of Quercus acutissima stands after five years of forest fires in Yesan.
