Abstract
Carbon isotope composition of peats in wetlands has been widely studied to understand paleoenvironment. In this study carbon isotope ratio (^<13>C/^<12>C) of the holocellulose and lignin components of peat in the Ozegahara Wetland were measured separately. The δ^<13>C values of the untreated peat show a decrease with the sampling depth. The reason for the decrease has been proved that the lignin compornent having lower δ^<13>C value became more dominant with the increasing depth. Lignin is more preservative than holocellulose and it is considered that the δ^<13>C value of lignin gives more straightforward information of paleoenvironment. The change of the δ^<13>C value resembles that of the burial rate based on ^<14>C-age, which is corrected assuming that only holocellulose have decayed exponentially. It is likely that the growth of plants in the Ozegahara Wetland increased between 7000 to 2000 years before present.
