Abstract
This study was conducted to understand the biomass and the energy content of 48-year-old Pinus densiflora stand planted in Mt. Wolak, Jecheon-si, Chungcheongbuk-do, Korea. The total biomass of aboveground was 138.14 ton/ha (87.3 ton/ha from stemwood, 41.43 ton/ha from live brances, and 9.41 ton/ha from leaves). Annual net production (ANP) of aboveground was 10.85 ton/ha/yr, and the ANP of stemwood, live branches, and leaves were 5.3 ton/ha/yr, 2.93 ton/ha/yr, and 2.62 ton/ha/yr, respectively. Energy content of aboveground was 2,981 GJ/ha, and annual energy accumulation was 239 GJ/ha/yr. The leaf area index (LAI) of P. densiflora stand was 6.58.
충북 월악산 동사면(해발 300m)에서 48년생 소나무 천연림의 바이오매스와 연간 순생산량을 추정한 결과, 소나무림의 바이오매스는 줄기부 87.3 ton/ha, 가지부 41.43 ton/ha, 잎 9.41 ton/ha로서 지상부 전체가 138.14 ton/ha로 추정되었으며, 연간 순생산량은 줄기부 5.3 ton/ha/yr, 가지부 2.93 ton/ha/yr, 잎 2.62 ton/ha/yr로서 지상부 전체 10.85 ton/ha/yr로 추정되었다. 또한 소나무림 지상부의 에너지량은 2,981 GJ/ha, 연간 에너지 고정량은 239 GJ/ha/yr로 나타났다. 한편, 월악산 지역 소나무림의 엽면적지수는 6.58로 나타났다.
