Biomass Carbon Emissions according to Conversion of Forest Land in Korea

산지전용에 따른 우리나라의 임목바이오매스 탄소배출량

This study was achieved by purpose to measure carbon emissions by conversion of forest land in Korea to correspond to UNFCCC. The conversion of forest land data extracted in forest basis statistical data during the latest 5 years from 2000 to 2004, and biomass carbon emissions used biomass extension factor by forest types and carbon conversion factor. During the latest 5 years, the forest land of the annual means about 7,200ha was conversed as other expenditure and tree volume of the annual mean about $212,000m^3$ was felled. It was calculated that total biomass carbon emissions by conversion of the forest land emits annual mean 105,000tC during the latest 5 years. Biomass carbon emissions by forest types was calculated that coniferous forest emits 54,000tC and deciduous forest emits 51,000tC. It was calculated that carbon emissions per ha by conversion of the forest land emits annual mean 14.4tC/ha during the latest 5 years. Seeing by forest types, coniferous forest emits 13.3tC/ha and deciduous forest emits 18.5tC/ha. Therefore, it was shown that deciduous forest emits more carbon per unit area than coniferous forest.

본 연구는 기후변화협약에 대응하기 위해 우리나라의 산지전용에 따른 탄소배출량을 측정할 목적으로 수행되었다. 산지전용자료는 2000년부터 2004년까지 최근 5년간 산림기본통계자료에서 추출하였으며, 임목바이오매스 탄소배출량은 임상별 바이오매스 확장계수와 탄소전환계수를 이용하였다. 최근 5년동안 산지전용면적은 연평균 약 7.2천ha가 타용도로 전용되었으며, 임목축적은 연평균 약 212천$m^3$이 벌채되었다. 최근 5년간 산지전용에 따른 임목바이오매스 총탄소배출량은 연평균 105천tC 배출한 것으로 나타났으며, 임상별 임목바이오매스 탄소배출량은 침엽수림이 54천tC, 활엽수림이 51천tC 배출한 것으로 나타났다. 최근 5년간 산지전용에 따른 ha 당 탄소배출량은 연평균 약 14.4tC/ha으로 나타났으며, 임상별로는 침엽수림이 약 13.3tC/ha, 활엽수림이 18.5tC/ha로 나타났다. 따라서 활엽수림이 단위면적당 탄소를 더 많이 배출하는 것으로 나타났다.
