摘要:The observation data from 30 meteorological stations was used to research the thermal regime of various types of soils in Armenia. The present study analyses the features of the heat exchange in the soil and air system, how the soil surface temperature varies with the location’s elevation, the surface thermal regime of various types of soils and the patterns of heat distribution in the surface and deep layers of soil. These results, together with the earlier research conducted on the soils of Georgia, give a clear picture of the thermal regime of various soils in the Transcaucasia region.
