- Аннотация: A set of well-developed paleosols was described in the floodplain of the Moskva River (Nikolina Gora, Russia). The lower soil of Boreal-Atlantic age contains pollen of steppe plants, pollen of conifers and charcoal are absent. The soil has a dark-colored humus layer typical for grassland soils. It indicates that in the first half of the Holocene the landscapes of the floodplain were open: there was a steppe with some tundra elements in the early Holocene and forest-steppe through the AT. In the Subboreal and Subatlantic, soils have light-colored humus horizons, and Subatlantic Soil 2 has a well-developed horizon Bt. Pollen and charcoal data suggest that spruce forests were widespread in the floodplain in the second half of the Holocene. Some signs of economic activities, such as the pollen of ruderal plants and charred seeds of weeds, appear at the end of the formation of the Atlantic soil and correspond to the Neolithic. Some signs of local disturbances of the vegetation cover are also noted in the pollen spectra of the Bronze Age cultural layer. In the Subatlantic soils, there are many traces of intensive development of the floodplain associated with the economic activity of the population of the Iron Age and early Middle Ages. A comparison of soil data with the distribution of archaeological sites indicates deforestation of the floodplain and the continued existence of anthropogenic grasslands and meadows within a radius of 1 km from the settlements.
