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.
본 연구는 제주도 곶자왈습지에서 서식하는 상록활엽수인 종가시나무의 지상부 생물량에 대한 상대생장식을 개발하기 위 하여 수행되었다. 그 결과 독립변수가 DBH일 때, 줄기(Ws), 가지(Wb), 잎(Wl) 그리고 지상부(Wab)의 상대생장식은 각각 logWs=2.4042logDBH-1.3045, logWb=2.6436logDBH-1.6232, logWl=1.5428logDBH-1.3692 그리고 logWab=2.3324logDBH-0.9181 이었다. 독립변수가 D2H일 때, 줄기(Ws), 가지(Wb), 잎(Wl) 그리고 지상부(Wab)의 상대생장식은 각각 logWs=0.853log D2H-1.4252, logWb=0.8453logD2H-1.5834, logWl=0.5328logD2H-1.4073 그리고 logWab=0.8265logD2H-1.0327이었다. 독립변수가 DBH일 때, 줄기, 가지 잎 그리고 지상부 상대생장식의 R2값은 0.9873, 0.9711, 0.7979 그리고 0.993 이었고 독립변수가 D2H일 때 0.9841, 0.9174, 0.7537 그리고 0.9876 이었다. 독립변수가 DBH인 상대생장식과 D2H인 상대생장식은 모두 관측 값과 예측값 사이에 통계적으로 유의한 차이가 없어 어느 상대생장식을 사용하더라도 결과에는 차이가 없었다.
