Aboveground Carbon Storage of Quercus acuta Stands by Thinning Intensity

This study was carried out to estimate aboveground carbon contents associated with four years of thinning treatment of Quercus acuta stands in Wando Arboretum, Jeonnam. Stand thinning was conducted over four years using stand table projection for each thinning treatment. Ten sample trees were cut in the surveyed area. Estimation of aboveground biomass was made using the equation model $W=aD+bD^2$ where W is oven dry weight and D is DBH in cm. The total aboveground biomass for each intensity treatment area was : control (148.4 ton/ha), light (105.6 ton/ha), moderate (68.7 ton/ha) and heavy (39.1 ton/ha). Aboveground carbon storage for Quercus acuta stands was found by multiplying dry weigh t (ton/ha) by 0.5. Carbon storage and increment after four years was: control (74.2 tonC/ha), light (52.8 tonC/ha), moderate (34.3 tonC/ha) and heavy thinning intensity area (38.2tonC/ha).

붉가시나무 간벌강도에 따른 지상부 탄소고정량에 관한 연구

본 연구는 전라남도 완도수목원의 붉가시나무 간벌처리구 임분의 4년 뒤 지상부 탄소고정량을 추정하기 수행되었다 간벌 처리구별 4년 뒤의 임분 생장은 임분예측표를 이용하였으며, 지상부의 건중량 분포는 $W=aD+bD^2$의 모형식을 이용하여 추정하였다. 간벌 처리구별 지상부 생체량은 대조구(148.4 ton/ha), 약도처리구(105.6 ton/ha), 중도처리구(68.7 ton/ha) 그리고 강도처리구(39.1 ton/ha) 분포를 보였다. 붉가시나무의 4년 뒤 간벌처리구별 탄소고정량은 건중량에 0.5를 곱하여 구하였으며, 대조구(74.2tonC/ha), 약도처리구(52.8tonC/ha), 중도처리구(34.3 tonC/ha) 그리고 강도처리구의 탄소고정량은 38.2 tonC/ha으로 조사되었다.
