Abstract
This study was conducted to develope allometric equations and to estimate biomass, stem density, and biomass expansion factor for the three stand age classes (I-II, III-IV, and V-VI) of Japanese larch (Larix leptolepis) in Gapyeong area. Total dry weight (kg/tree) and aboveground biomass (ton/ha) were 57.8 and 71.1 for I-II class, 185.4 and 195.6 for III-IV class, and 1047.9 and 180.6 for V-VI class, respectively. Total above and belowground biomass (ton/ha) was 96.3 for I-II class, 265.7 for III-IV class, and 244.5 for V-VI class. The proportion (%) of stem to total biomass increased with stand age class and was 53.9 for I-II class, 55.7 for III-IV class, and 57.7 for V-VI class, respectively, while that of foliage decreased and was 7.1 for I-II class, 4.5 for III-IV class, 2.3 for V-VI class. Ratios of root to aboveground biomass were 0.35 for all age classes. Stem density (
본 연구는 경기도 가평군 일대의 낙엽송 임분 3개 영급 단위(1-2영급, 3-4영급, 5-6영급)에서 바이오매스 추정식을 개발하고 이를 바탕으로 바이오매스, 줄기 밀도, 바이오매스 확장계수를 추정한 것이다. 1-2영급, 3-4영급, 5-6영급에서 낙엽송 개체목의 평균 건중량(kg/tree)은 각각 57.8, 185.4, 1047.9, 지상부 바이오매스(ton/ha)는 71.1, 195.6, 180.6, 임목 전체 바이오매스(ton/ha)는 96.3, 265.7, 244.5 등으로 나타났다. 영급 단위가 증가함에 따라 줄기의 구성비(%)는 53.9, 55.7, 57.7 등으로 증가하였지만 잎의 구성비는 7.1, 4.5, 2.3 등으로 감소하였다. 뿌리와 지상부의 건중량 비는 모든 영급 단위에서 0.35로 나타났다. 줄기 밀도(
