抄録

Peatlands are well developed in the alluvial lowlands around Lake Kutcharo and the Tonbetsu River Lowland in Hokkaido. In general, the evolution of these peatlands have been influenced by Holocene environmental changes such as sea-level changes. The purpose of this study is to report the AMS radiocarbon dating results of the Holocene peat Layers obtained from the Tonbetsu River Lowland. Some soil samples of the upper Holocene sediments were taken from the Tonbetsu River Lowland by using peat-corer. We obtained three radiocarbon dates of these samples by a Tandetron AMS at Nagoya University. Radiocarbon dates of the lowermost horizons of peat layers are 4,540±95yrBP (NUTA-5651), 4,780±220yrBP (NUTA-5652) and 2,260±250yrBP (NUTA-5654). These dates are similar to radiocarbon dates of the Hokkaido.
