For the estimation of greenhouse gas dynamics in forests, it is useful to use a model which simulates both carbon (C) and nitrogen (N) cycle simultaneously. A forest C model, called FBDC, was developed and validated in Korea. However, studies on development of forest N model are insufficient. This s...

전 지구적인 관점에서 산림 역할은? | 산림은 전 지구 탄소 및 질소 순환에서 중요한 역할을 한다. 육상생태계에 저장된 탄소 중 절반 이상이 산림에 저장되어 있고, 질소 강하물의 상당량이 산림을 통해서 유입되기 때문이다(Cox et al. | |
한국형 산림 탄소 모델인 FBDC을 이용해 가능한 사항은? | 국내에서 온실가스 동태를 모의하는데 활용할 수 있는 한국형 산림 탄소 모델인 FBDC (Forest Biomass and Dead organic matter Carbon) 모델이 개발된 바 있으며, 이 모델을 이용하여 탄소 인벤토리 보고 항목인 임목, 낙엽층, 고사목, 토양 탄소의 변화를 국가 단위에서 추정하는 것이가능하다(IPCC, 2006; Yi et al., 2013; Lee et al. | |
탄소 및 질소 순환이 서로 유기적으로 연결되어 있음을 보여주는 내용은? | 탄소 및 질소 순환은 서로 유기적으로 연결되어 있다(Schulze, 2000). 즉, 토양 내 질소 유효도는 임목의 광합성과 생장을 제한하여 산림의 CO2 흡수량에 영향을 미치고, 임목의 CO2 흡수량 변화는 토양에서 임목으로 이동하는 질소의 양을 변화시킨다(Yoon et al., 2015). 또한 고사유기물이 분해되고 토양 내 질소가 식물이 이용 가능한 형태로 전환되는 속도는 탄소와 질소의 상대적 비율에 의해 조절된다(Yoon et al., 2014). |
