Abstract

Paleolimnological studies of the Lososinskiy Reservoir (Karelia) have made it possible to reconstruct the history of its development from the Ice Lake to the artificial waterbasin. Five stages of sedimentogenesis were identified. It was based on lithostratigraphy, diatom and geochemical analysis of bottom sediments. The detailing of the anthropogenic period of the Lososinskiy Reservoir was carried out on the study of the landscape structure of the catchment area using the mass-balance production model of the ecosystem.
