 note = {To elucidate carbon supply mechanism in forest soil, the spatial and depth variations in organic carbon content and carbon isotope ratio (δ13C, Δ14C) in litter and soil were measured by the field observation, and the temporal variations in evolution rate and δ13C value of CO2 derived from organic matter decomposition were measured by the incubation experiment. We selected a mixed forest of cypress and pine trees as a research site(Inabu, Toyota City, Aichi Pref., 35°198' N, 137°574' E) with an altitude of 1200m above sea level. In the field observation, while the litter falls were supplied evenly to forest floor, the inhomogeneous distribution of organic carbon was formed at L layer and the distribution of surface soil was not influenced by the inhomogeneous distribution of L layer above it. The δ13C value of L layer was 2.5‰ less than that in surface soil. The Δ14C value of surface soil was negative. It suggested that the accumulation rate of organic carbon into surface soil was slow. In the incubation experiment, the evolution rates of CO2 from Layer decreased moderately after 20 d incubation, on the other hand that of surface soil showed rapid decrease for 10 d after just starting the incubations, and then they decreased moderately. During incubations, the δ13C values of CO2 from L layer were always higher than δ13C value of total organic carbon in L layer. The mismatch of δ13C values between L layer and surface soil organic carbon could not be explained by the δ13C value of L layer decomposition residues estimated from the incubation experimental results. It suggested the carbon balance in surface soil at this forest could not be explained by the carbon supply process that surface organic carbon in soil was formed by L layer residues., 名古屋大学年代測定総合研究センターシンポジウム報告},
