Abstract

Crown fuel characteristics such as crown bulk density, crown base height, and fuel moisture content of Japanese red pine were analyzed. Ten trees in Mt. Palgong at Daegu, were destructively sampled and their crown fuels were weighed separately for each fuel category. Fuel content of live and dead crown component were 53%, and 15.3%, respectively. Foliar moisture content was 56%. Needles and twigs with diameter less than 1cm diameter accounted for 16.2%, 55% of total and crown fuel load. Average crown bulk density of Japanese red pine was 0.24 kg/$m^3$, effective crown fuel bulk density was 0.1325 kg/$m^3$.

본 연구에서는 우리나라에서 수관화에 취약하다고 밝혀진 소나무림을 대상으로 수관층의 연료특성을 잎과 가지 굵기 별로 구분하여 수분함량, 연료밀도로 제시하고자 하였다. 이를 위해 대구 팔공산에서 소나무 10그루를 벌채하여 각 부위별로 건중량을 측정하였다. 분석결과 수관층 살아 있는 부위의 평균 수분함량은 53%, 죽은 부위는 15.3%였으며, 생엽의 수분함수율은 평균 56%이었다. 수관화 확산시 실제적으로 연소되는 잎과 직경 1 cm 이하의 가지를 합한 연료량은 전체 바이오매스에서는 16.2%, 수관층 바이오매스에서는 55%를 차지하였다. 수관 연료밀도는 평균 0.24 kg/$m^3$이었으며, 잎과 1 cm 굵기 이하의 가지를 합한 유효 수관연료밀도는 0.1325 kg/$m^3$이었다.
