抄録
内容記述 Coarse woody debris (CWD) include large woody litter such as boles, snags, and stumps and are major components of organic carbon in forest ecosystems, accounting for more than 40% of the aboveground biomass in some forests. In the present study, we develop a new method using radiocarbon dating to estimate the dead year and decomposition rates of CWD. The method merits the estimation of dead year for bulk CWD samples that are either drilled or excised as a disk. We establish mathematical models that incorporate the diameter of sample, allometric relationship between diameter and tree age, and background values of atmospheric 14CO2 concentration to construct reference curves for the estimated 14C values of bulk CWD sample with respect to the dead year. We verified the accuracy of this method by measuring Δ14C values for five CWD samples (diameter of 20-23 cm, dead year known or unknown) collected in a subalpine forest in central Japan and comparing the estimated values of dead years and decomposition rates with those previously observed.
