This study compared soil CO2 efflux rates after fertilization, in Pinus densiflora and Quercus variabilis stands. Compound fertilizers were applied to the forest floor in March 2016, following a one-year calibration period (from March 2015 to February 2016). In situ soil CO2 efflux rates were measur...

산지 시비란 무엇이고 그 역할은? | 산지 시비는 대기 중 온실가스인 CO2의 흡수 능력 향상에 가장 효과적인 수단으로(Kim, 2008; Moscatelli et al., 2008) 제공될 수 있으며, 산림생태계의 중요한 기능인 산림생산력 증진, 산림 건강도 및 양분 유효도 향상, 산림 토양 내 양분 수지의 조절 등과 관련한 다양한 혜택을 증진한다. 이는 산지 시비 후 토양의 생물학적이나 화학적 프로세스의 변화로 인하여 지상부와 지하부 탄소재분배 기작 발생, 유기물 분해나 토양 호흡 변화, 미생물 활동 및 토양 pH 등에 영향을 미치기 때문이다(Erickson et al. | |
경상남도 진주시의 30년 간 연평균 강수량과 연평균 기온은? | 본 연구 조사지는 경상남도 진주시 국립산림과학원 “월아연구시험림” 내 성숙한 소나무와 굴참나무 임분을 대상으로 하였다. 최근 30년 동안(1981∼2010년) 이 지역의 연평균 강수량은 1,513 mm, 연평균 기온은 13.1℃이다. 조사지는 유사한 입지환경에 서로 인접하며, 정상적으로 생육하고 있는 V영급 이상의 성숙하고 건전한 소나무와 굴참나무 임분을 선정하였다. | |
지구온난화 관련 주요 온실가스에는 무엇이 있는가? | 산림생태계로부터 흡수되거나 방출되는 지구온난화 관련 주요 온실가스는 크게 이산화탄소(CO2), 메탄(CH4), 아산화질소(N2O)로 이들이 지구 대기환경에 미치는 영향은 매우 크다(Bravo et al., 2008). |
