Abstract

Globally, the forest fires are a significant contributor of carbon dioxide and other greenhouse gases in the atmosphere. In this study, fuel load consumed by forest fire and emission of green house gases were analysed in the surface layer. For this, remaining fuel was collected and weighed with the species (Japanese red pine, deciduous) and the forest fire types (surface fire, crown fire) in the 51 forest fires. 8,361 kg/ha fuel load was consumed in deciduous forest damaged by surface fire, and 8,055 kg/ha, 12,333 kg/ha in Japanese red pine burned by surface fire and crown fire. The combustion ratios were 78, 59, and 90%, respectively. 15,856 kg/ha the green house gases such as $CO_2$, $CH_4$, $CH_4$ in deciduous forest burned by surface fire was emitted and 14,834 kg/ha, 22,709 kg/ha in Japanese red pine burned by surface fire and crown fire.

산불은 전 세계적으로 다량의 온실가스를 배출하여 지구온난화에 기여한다. 본 연구에서는 산불로 인한 지표층 연료의 연소량과 이로 인한 온실가스 배출량을 분석하고자 하였다. 이를 위해 51개 산불을 대상으로 소나무림과 활엽수림으로 구분하고, 다시 지표화와 수관화 피해 지역으로 나누어 잔존 연료량을 채취하여, 미연소 지역의 연료량과 일원분산분석을 수행하였다. 그 결과 활엽수 지표화 지역은 8,361 kg/ha, 소나무 지표화 지역은 8,055 kg/ha, 소나무 수관화 지역은 12,333 kg/ha이 연소되어, 수종별 산불행태별로 차이가 있었다. 이때의 연소율은 각각 78, 59, 90%이었다. 이산화탄소, 메탄, 아산화질소 등의 온실가스 배출량은 활엽수 지표화 연소지역 15,856 kg/ha, 소나무 지표화 연소지역 14,834 kg/ha, 소나무 수관화 연소지역은 약 22,709 kg/ha이었다.
