This study developed allometry equation and estimated the aboveground-biomass of Quercus glauca, a warm-temperature, evergreen broad-leaved tree, growing in Kotzawal wetland located on Jeju Island. The allometric equations between DBH(diameter at breast height) and dry weights of stems (Ws), branches (Wb), leaves (Wl) and aboveground biomass (Wab) of Q. glauca were as follows: logWs=2.4042logDBH-1.3045, logWb=2.6436logDBH-1.6232, logWl =1.5428logDBH-1.3692 and logWab=2.3324logDBH-0.9181. The allometric equations between D2H and Ws, Wb, Wl, and Wab of Q.glauca were as follows : logWs=0.853logD2H-1.4252, logWb=0.8453logD2H-1.5834, logWl=0.5328logD2H-1.4073 and logWab=0.8265log D2H-1.0327. The R2 between DBH and Ws, Wb, Wl and Wab were 0.9873, 0.9711, 0.7979 and 0.993, respectively. The R2 between D2H and Ws,Wb,Wl and Wab were 0.9841, 0.9174, 0.7537 and 0.9876, respectively. There was no significant difference between observed and calculated values of the allomatric equations from DBH and D2H(p>0.05, Kolmogorov? Smirnov test). Thus, to estimate the aboveground biomass of Q. glauca, use of DBH and D2H as an independent variables in the allometric equation is recommended.
