摘要

Dynamics of vegetation and climate of the Paanajarvi National Park, Russian Karelia, in the Holocene were studied by geobotanical, mire, palaeobotanical and radiocarbon methods. In addition to palaeobotanical methods, some living organisms such as algae, fungi, Rhizopoda and Rotatoria were also analysed. Forests were the dominant vegetation type since the mid-Boreal period (8500 BP). The following succession occurred: north-taiga pine forests combined with thin birch forests (8500-8000 BP); north-taiga birch-pine forests (8000-7200 BP); middle-taiga pine forests (7200-5200 BP); middle-taiga spruce forests with thin pine forests (5200-2500 BP); north-taiga spruce forests with individual pine forests (2500 BP to the present). The evolutionary stagesof forest and mire vegetation are correlated with changes in hydrological regime and climate. It is shown that the former lake regime can be reconstructed by analysing the composition of algae and other organisms.
