Climatic Changes, Successions of Peatlands and Zonal Vegetation, and Peat Accumulation Dynamics in the Holocene (the West-Siberia Peat Profile ‘Vodorasdel’)

摘要

The developmental history of peatland and dry land vegetation within the Ob-Vasugan watershed of Western Siberia was characterized according to features of the plant communities and climatic changes which were revealed by stratigraphic, spore-pollen and C14 (carbon) data obtained from a vertical peat profile ‘Vodorasdel’. Changes in the paleoecological environment over the last 10000 years were divided into five periods. The climate was characterized in the Holocene according to these periods. At the watershed studied, peatland-forming processes started about 9510 years ago resulting in 550 cm of peat accumulation. The rate of peat accumulation within the watershed decreased over time from 1.9–0.3 mm year− 1.
