英文摘要
To clarify possibility of fossil carbon decomposition in soil in Arctic tundra ecosystem, we collected soil gas CO_2 and determined its date in Spitsbergen Island, High Arctic Norway. Soil gas CO_2 collected from 30-40 cm depth from soil surface was dated on the age of 3, 000-7, 000 year BP. Our results suggested that CO_2 derived from fossil carbon contributes soil respiration and decomposition rate of the fossil carbon may be accelerated if soil temperature increase.
