The soil-geochemical features of permafrost-taiga geosystems characteristic for the Yerbogachenskaya plain are outlined. The differentiation of a number of chemical elements in soils is considered to be the result of their radial, lateral migration and accumulation on the permafrost barrier. The indicator function of some species of mosses and lichens in the assessment of changes in the biogeochemical environment is demonstrated.
