To clarify the behavior of carbon in terrestrial ecosystem, soil CO_2 effluxes were measured in a deciduous forest by using closed chamber method. Soil temperature mainly took part in seasonal variation in soil CO_2 efflux from the forest floor. The contribution of litter decomposition to soil CO_2 efflux was evaluated as 27 % or less. By using carbon isotope, the contributions of soil respiration sources were evaluated. Root respiration was promoted in the time of growth of vegetation, and decomposition of soil organic matter was promoted in the time when soil temperature was high. It was confirmed that not only soil temperature but also forest floor temperature influenced litter decomposition.
