열대 우림을 대상으로 하는 탄소 정량화 연구가 필요한 배경은? | 육상생태계 중 가장 넓은 면적을 차지하는 열대우림은 육상생태계 탄소 저장량의 55%, 연간 탄소 저장량의 70%를 차지하며, 전 세계 탄소 순환과 기후변화에 큰 영향을 미치고 있다(FAO, 2011; Pan et al., 2011). | |
(LiDAR) 자료가 산림의 수직적 구조 분석에 효과적인 이유는? | 해외조림, Reducing Emissions from Deforestation and Forest Degradation (REDD) 등 기후변화 저감과 관련된 국내외관심이 여전히 계속되고 있으며 이와 관련하여 산림 탄소의 정량화 기술을 개발하는 연구가 주목을 받고 있다. Light Detection and Ranging (LiDAR) 자료는 수관의 표면 뿐 아니라, 수관을 통과하여 지표면의 반사값을 기록할 수 있으므로 산림의 수직적 구조 분석에 효과적이다(Drake et al., 2003; Lefsky et al. | |
항공 LiDAR 자료의 장점은? | , 1999).항공 LiDAR 자료는 상층 반사 값에서의 정확한 수고 측정이 가능하다(Blair et al., 1999; Lefsky et al., 2002). 또한,항공 LiDAR 자료는 식생의 높이나 지상고도 뿐만 아니라 경사지나 울폐림을 측정하는데 높은 정확성을 갖는다(Popescu et al., 2011). |
