Carbon Dynamics in Boreal Forest and Tundra Soils, Alaska - CO2 and CH4 Emissions -

CONCLUSIONS 1) Different production processes of CO2 and CH4 from manipulated Arctic coastal tundra, 2) CO2 emission in drained section from ecosystem respiration, 3) CH4 production in the inundated section from metanogenesis, 4) Expansion of tundra lakes, implying enhanced CH4 release, and 5)Disappearance of lakes, connected to stimulated CO2 emission in the Arctic.结论 1）经调控的北极沿海苔原，其二氧化碳（CO₂）与甲烷（CH₄）的产生过程存在差异； 2）疏水区的二氧化碳排放源自生态系统呼吸作用； 3）淹水区的甲烷产生源自产甲烷作用； 4）苔原湖泊面积扩张，意味着甲烷释放量增加； 5）北极地区湖泊消失与二氧化碳排放增强存在关联。
