월악산 24년생 잣나무 인공림의 바이오매스와 에너지량
Biomass and Energy Content of Pinus koraiensis Stand Planted in Mt. Wolak <Mokchae Konghak 34(4):66-75, 2006> Corresponding author kkch30@yahoo.co.kr
ABSTRACT
This study was conducted to understand the biomass and the energy content of 24-year-old Pinus koraiensis stand planted in Mt. Wolak, Chungcheongbuk-do, Republic of Korea. Nine sample trees were selected and harvested for the study. Stem, bark, branches and leaves were weighed respectively with the stratified clipping method, and analyzed for productive structure. The allometric regression equations between dry weight of each component and D2H were obtained to estimate the total biomass of aboveground (47.0 ton/ha) and other parts (56.5% from stemwood, 9.1% from stembark, 0.5% from current twigs, 18.4%from live branches, 2.6% from current leaves, and 12.9% from previous leaves). Annual net production of aboveground was 6.0 ton/ha/yr, and the ratios of stemwood, stembark, current twigs, live branches, and current leaves to that of aboveground were 49.8%, 7.3%, 3.5%, 18.6%, and 20.8%, respectively. Energy content of aboveground was 1,028 GJ/ha, and annual energy content was 133GJ/ha/yr. Leaf area index (LAI) of Pinus koraiensis plantation was 20.2 in Mt. Wolak.
