Mapping the Main Characteristics of Permafrost on the Basis of a Permafrost-Landscape Map of Yakutia Using GIS

The purpose of this article was to compile four separate digital thematic maps temperature and ice content permafrost, the active layer thickness, cryogenic processes in Yakutia as a basis for assessing changes modern climate anthropogenic disturbances. In work, materials on permafrost were used, serving compiling landscape map Republic Sakha (Yakutia). compiled using ArcGIS software, which supports attribute table mapping. ground thickness reflected zonality regional differences. Peculiarities genetic types Quaternary deposits climatic conditions surface sediments process distribution maps. One most common is temperatures from −2.1 −4.0 °C, found occupy about 37.4% territory Yakutia. More than half region be occupied by landscapes with limited up 1.1 m. Ice-rich (more 0.4 content) typical 40% territory. Thermokarst hazardous that occurs
