Simultaneous observations of the accumulation of soil organic carbon, the rate of litterfall and soil respiration were made periodically over a period of one year in a preserved cool-temperate beech/fir forest on Mt. Odaigahara, Nara Prefecture, central Japan. Based on a simple compartment model of the dynamics of soil carbon, it was shown that the carbon cycling in the soil was considerably slower in this forest than that in the driest stand of warm-temperate evergreen oak forest, owing to lower temperature and probably to the perhumid condition of soil throughout the year. The seasonal variation of the dynamics was also analyzed by the same model to show comparatively high decomposition rates of soil organic carbon in mid-summer, lower rates in other parts of growing season, and the interruption of decomposition under snow cover during winter months.
