The surface palynological spectra of different phytocoenoses in the south of the Tyumen region

The palynological spectra of different phytocoenoses in the south of the Tyumen region were analyzed in the article. Forty-one periblastic soil samples were investigated with palynological/spore-pollen analysis. More than twenty thousand pollen grains and spores identified with bloodline or genus. Four possible plant communities were revealed, which differed from each other by the type of dominant vegetation. Interest allocation of pollen and spores of various taxonomies was ranked depending on a phytocoenosis. The proportion of tree vegetation’s pollen in meadows was 1.2 times less than in woods. The dominance of pine bloodline’s pollen was recorded in all groups. The expediency of the application of palynological analysis as a method of indicating the effects of anthropogenic impacts on phytocoenoses was proved with the example of artificial non-natural ecosystems. The pollen markers of anthropogenic impact were identified.
