The paper presents the results of humus isotopic composition and radiocarbon age of the buried soils determining in the mountain soils of Dagestan.  General chemical properties and properties of soil organic matter of modern and buried soils of Inland Daghestan are investigated. It was found that the Preboreal and Atlantic optimums of Holocene in Eastern Caucasus were characterized by a droughty climate while the Medieval period climate can be characterized as a moderate one, similar to the climate of our time. Little ice age period was absent in Daghestan. It is shown that the anthropogenic use of mountain landscapes leads to their stepping down contrary to natural climatic trends

Keywords: mountain soils, Holocene, palaeoenvironment, carbon isotopic composition.
