Dynamics of Forest Vegetation and Climate in the Southern Taiga of Western Siberia in the Late Holocene According to Spore-Pollen Analysis and Ams Dating of the Peat Bog

摘要

The reconstruction of the dynamics of natural and climatic conditions according to the spore-pollen analysis and AMS dating of the peat section of the south-taiga watershed of the bog swamp massif in western Siberia is presented. The dynamics of regional forest vegetation was reconstructed for the last 4200 years. The period of cryogenic termination of peat accumulation of 2995-2215 before present (BP), as well as climatic changes in the thermal and humidity regimes, was determined. The cooling periods in the last millennium coincide with the minima of solar activity: Oort; Wolf; Shperer; Maunder; and Dalton.
