| Abstract: | 季節凍土では融雪期に短期集中的な亜酸化窒素（N2O）の排出が見られる. 著者らはその現象を積雪操作実験で再現することに成功した. 本稿では2008年11月から2010年10月にわたる野外観測の結果に基づいて, 積雪深・土壌凍結深とN2Oの土壌中での蓄積・土壌から大気へのN2Oの排出の関係を考察するとともに, 未解決の課題を提示する. | | Seasonally frozen soil has substantially high N2O emission under thawing conditions. We succeeded in insitu observation of the N2O emissions in a snow-cover manipulation experiment. Here, we discuss relationships among snow-cover height, soil frost depth, N2O concentration in soil and process of N2O release from soil to the atmosphere. In addition, unsolved issues are presented. |
