PALEOECOLOGICAL CHARACTERISTICS OF THE HOLOCENE IN THE OB-VASYUGAN INTERFLUVE ON THE BASIS OF DATA COLLECTED IN THE VODORAZDEL PEAT PROFILE

A peat profile, 5.5 m in depth, laid in a bog complex comprising frost mounds, bog hollows, and lakes was studied. This bog complex was loca ted in one of the most swamped regions of the middle taiga of the West Siberian Plain. Botanical and spore-pollen analyses of the peat field were conducted. Across the thickness of the peat deposit, 17 points a t 25-cm intervals were dated by the radiocarbon method. The dynamics o f vegetation and climate during the past 9500 years were determined. I t was revealed that, during this period, the rate of peat accumulation constantly tended to decrease, with some fluctuations. The results of mathematical and ecological simulation of this process predict that i t will cease in another 1000 years.
