摘要

Development and dynamics of zonal vegetation in the area between recent northern taiga forests and tundra (with some properties of forest-tundra zone) in the north-west of Kola Peninsula have been studied based on two original standard pollen-spore diagrams. One of them characterizes pine forest at northernmost limit of their geographic distribution, the second diagram shows the tundra-forest-tundra contact area. The distance between investigated territories did not exceed 60-70 km. Such diagram locations enable both to carry out a comparative analysis of palaeovegetation dynamics for different geographic zones and to follow a temporal-spatial shifting of the taiga-tundra border. The data obtained showed that about 9300 years ago in the west of investigated region, tundra vegetation gave place to birch woods. About 7800 years ago they were replaces by pine forests that still exist there in their original form. Two successions have been recorded at the zonal level in the north of the territory. About 8000 years ago tundra vegetation for the first time gave place to forests which in turn were replaced by tundra vegetation about 4800 years ago.
