낙엽기질의 질을 결정하는데 중요한 요인은 무엇인가? | 낙엽의 질은 낙엽의 분해능을 조절하는 요인으로 정의하기는 힘들지만, 분해율과 높은 상관관계를 나타낸다. 낙엽의 물리적 구조뿐만 아니라 화학적 조성, 즉 질소의 함량, 리그닌의 함량은 낙엽기질의 질을 결정하는데 중요한 요인이며(Melillo et al., 1982; Cotrufo et al. | |
식생의 분포역을 결정하는 요인은 무엇인가? | 한편 최근 온난화에 의한 기후변화는 세계적 관심사인데 이러한 온난화에 따라 전체 식생의 분포역은 달라질 것으로 예상되고, 한편으로는 난대성 식물의 북상도 예상된다. 이들 식생의 분포는 기온, 강수량, 온량지수, 대륙도, 지질상태 등에 의해 결정되어 지는 것으로 알려져 있다(Piao et al., 2004; Wang et al. | |
낙엽은 생태계 및 생물계에서 어떤 역할을 하는가? | 낙엽은 육상 생태계에서 영양원소의 주요 원천이며, 낙엽의 분해는 토양의 비옥도를 유지하고, 식물의 생장을 위한 영양원소의 방출 뿐 아니라 이산화탄소의 배출을 조절하는 생물계에서 가장 중요한 과정 중 하나이다. 본 연구는 지구온난화로 인해 그 분포역의 확대가 예상되는 상록활엽수인 동백나무를 대상으로 낙엽의 분해율 및 분해과정에 따른 영양원소의 함량 변화를 파악하기 위해 진행되었다. |
