Coarse woody debris (CWD), which is a component of the forest ecosystem, plays a major role in forest energy flow and nutrient cycling. In particular, CWD isolates carbon for a long time and is important in terms of slowing the rate of carbon released from the forest to the atmosphere. Therefore, th...

고사목의 정의는? | 일반적으로 고사목(Coarse Woody Debris; CWD)은 자연적인 요인(노화, 천이, 경쟁, 바람, 설해, 병충해 등)이 나 인위적인 요인(벌목, 산불 등)에 의해 발생한 조립질의 목질 유기물을 말하는데(Waring and Schlesinger, 1985), 고사목의 바이오매스는 성숙한 산림의 지상부 바이오매스 중 10 – 20%를 차지하는 중요한 산림생태계의 구성 요 소이다(Gough et al., 2007). | |
고사목은 산림생태계에서 어떤 역할을 하는가? | , 2007). 고사목은 완전히 분해될 때까 지 산림생태계에 오랜 기간에 걸쳐 영향을 미치기 때문에 산림의 생산성 증대, 생물의 서식처 제공, 지형의 안정 및 생물다양성의 기반제공 등의 생태적으로 큰 역할을 하며, 더불어 임상에 장기간 잔존하여 탄소의 장기 저장에 큰 역할을 한다(Stevens and Victoria, 1997). 고사목의 분해에 따라 방출되는 탄소는 CO2로서 대기로 유입하거나 계 내 (예; 토양이나 계류수)에 재분배되는데, 아마존 유역의 노 령림에서는 전자가 전체의 76%를 차지하기도 하며, 그의 연간 방출량은 1. | |
탄소의 장기 저장을 하는 고사목은 아마존 유역의 노경림에서는 어느정도의 탄소가 재분배 되는가? | 고사목은 완전히 분해될 때까 지 산림생태계에 오랜 기간에 걸쳐 영향을 미치기 때문에 산림의 생산성 증대, 생물의 서식처 제공, 지형의 안정 및 생물다양성의 기반제공 등의 생태적으로 큰 역할을 하며, 더불어 임상에 장기간 잔존하여 탄소의 장기 저장에 큰 역할을 한다(Stevens and Victoria, 1997). 고사목의 분해에 따라 방출되는 탄소는 CO2로서 대기로 유입하거나 계 내 (예; 토양이나 계류수)에 재분배되는데, 아마존 유역의 노 령림에서는 전자가 전체의 76%를 차지하기도 하며, 그의 연간 방출량은 1.9 Mg C ha-1로서 세립질의 지표유기물 (예; 낙엽이나 낙지)의 호흡량에 필적하기도 한다(Chambers et al., 2001). |
