ABSTRACT
Soil CO2 emission is one of the primary components in carbon balance of terrestrial ecosystems. To accurately assess their net ecosystem exchange of CO2 and net primary production, measurement of soil CO2 efflux is required along with that of canopy CO2 flux. In this paper, soil CO2 flux measurement technique using closed dynamic chamber systems is briefly reviewed. Preliminary results on soil CO2 exchange and inter-comparison of different measurement systems currently used in Korean regional network of tower flux measurement sites (KoFlux) are also reported.

적요

토양으로부터의 $CO_2$ 수식 이미지 방출은 생태계의 탄소 순환에 중요한 위치를 차지한다. 주요 생태계의 순 $CO_2$ 수식 이미지 교환과 일차 생산량 등을 정확히 산출하려면 군락 $CO_2$ 수식 이미지 플럭스와 더불어 토양 $CO_2$ 수식 이미지 플럭스의 관측이 함께 이루어져야 한다. 본 논문에서는 닫힌 역학 챔버 시스템을 활용한 토양 이산화탄소 플럭스의 관측 방법을 간략히 검토하고, 한반도 주요 생태계에 구축된 한국 타워 플럭스 관측 지역망(KoFlux)의 거점 관측소에서 예비 관측된 결과와 서로 다른 관측 시스템간의 상호비교 결과를 보고하고자 한다.
