We evaluated CO_2 budget and its dynamics of cypress forests based on a synthesis of field observation, satellite remote sensing, and terrestrial biosphere model. According to the synthesis, interannual variation of the CO_2 budget was strongly affected by those of climate variability, especially for the summer radiation and air temperature. On the other hand, the stand disturbance history was an important controlling factor to determine long-term trajectory of the carbon budget. In future study, the spatial map of stand history, such as forest age and past disturbance, is important for the projection of the regional carbon balance of Japanese plantations in addition to the spatial distributions of vegetation activities which are measurable by using satellite remote sensing.
