Unexplored soils of the Western Yakutia

Abstract

Analyzing the developed classifications by typology of soils permafrost, the author of article comes to a conclusion about existence in it "white spots". As additional approach in a context of expansion of systematization and classification of cryosols not studied types of soils, in a basis by which L.G. Elovskaya's classification is put are offered new early. The characteristic, properties and climatic and forest vegetation conditions of formation permafrost soils new to zone of an average taiga are given. These are forest gray and brown soils, characteristic for the forest-steppe zone, possessing potentially high fertility and which test now the intensive techno genic press, connected with production of hydrocarbons. Identification of soils of a sub boreal climatic zone in a boreal belt frozen ground happens for the first time that is connected with inaccessibility and spatial remoteness of the studied territories from the scientific organizations. Brown and gray types of soils are characteristic for the broad-leaved woods not permafrost areas and stay them under small-leaved and light-coniferous forests in conditions frozen ground is nonsense. Definition of genesis of these soils and probability of shift of the natural zones, caused by climate changes, demands further complex detailed researches.
