지구 온난화로 인한 기후 변화와 전망은? | 지구 온난화로 지난 133년간(1880-2013년) 대기 온도는 평균 약 0.85℃가 상승했으며, 21세기 말 지구의 평균기온은 현재보다 약 3.7℃ 상승(RCP 8.5 기준) 될 것으로 전망된다(Intergovernmental Panel on Climate Change, 2014). 기온은 수목의 생리 작용 및 생장 변화를 초래하는 주요 영향 인자로, 기후변화 시나리오에 근거한 온난화는 국내 침엽수림 분포의 북상에 영향을 미칠 것으로 예측된다(Ko et al. | |
양묘장에서 발생하는 묘목 피해의 주요 원인은? | 묘목의 품질과 생산성은 온·습도, 수분함량, 광량, 양분 조건 등 여러 환경 인자들에 영향을 받으며(Danby and Hik, 2007; Baribault et al., 2010), 특히 온난화와 함께 가뭄과 폭우가 빈번히 발생하는 상황에서는 이러한 기상재해가 주요 원인으로 여겨지고 있다(Allen et al., 2010). 이는 온도 변화와 수분 가용 조건이 잎의 기공 개폐에 직접적인 영향을 미쳐 증산과 광합성 작용 등의 생리활성을 변화시킴으로써 묘목의 생존과 생장에 직결되는 인자이기 때문이다(Wu et al. | |
온대 중·북부 지역에서 주요 조림 수종으로 권장되는 것은? | 현재 벌기령에 도달한 우리나라 산림에서는 목재 자원을 이용하고 다시 경제림을 조성하기 위한 선순환 정책 이 추진되고 있으며, 조림 면적의 확대에 대응하기 위해서는 안정적인 묘목 생산과 공급이 필요하다(Korea Forest Service, 2018). 특히 온대 중·북부 지역에서는 우수한 목재 가치를 가진 소나무(Pinus densiflora)와 낙엽송(Larix kaempferi)이 주요 조림 수종으로 권장되어 고품질 묘목의 안정적 공급이 요구되는 실정이다. 그러나 노지 양묘 및 조림 초기 단계의 묘목은 항시 기상재해의 위협에 노출되어 있기 때문에, 이들 수종의 생장 특성을 실외 실험적 처리 환경에서 구명하는 것은 고품질의 묘목 생산과 이와 연계된 우수한 조림 성과를 이루기 위한 측면에서도 중요하다(Kim et al. |
