英文摘要
Soil respiration and soil CO_2 concentration profile were measured during two rainfall events to investigate the effect of rainfall on soil respiration and soil CO_2 concentration. Those data were compared with gas diffusion coefficients in soil derived from observed soil temperature and moisture. As a result, soil CO_2 storage determined the patterns of soil CO_2 concentration and soil respiration during rainfall. The pattern was different among rainfall events due to different soil CO_2 regime which was induced by seasonality of rainfall and soil CO_2 production profile.
