Аннотация:Characteristics of 27 subfossil spore–pollen spectra of recent plant communities in larch forests of Central Evenkia. Although larch forests dominate in the study region, the main components of the spectra are Betula sect. Betula and Alnus alnobetula subsp. fruticosa, whereas the proportion of Larix pollen is reduced relative to that of larch trees in the vegetation and ranges from 0.6 to 13.5%. The proportion of Picea pollen increases at sampling points where spruce is a component of tree stand. Pinus pollen is a foreign component of the spore–pollen spectra, and its proportion increases in phytocenoses where the tree layer is sparse or absent. Species characteristic of taiga forests and wetland and meadow habitats and indicators of disturbed grounds and burned-out areas have been identified, which will allow a more detailed and objective reconstruction of paleovegetation.
