Abstract

Shown, that negative processes and phenomena often appear on the territory of big cities in the area of cryolithozone, such as inundation, thermokarst processes, ground subsidence, soil salinization and etc.; these processes are intensified under observed climate changes: inundation area increases, that lead to soil salinization, rise of mineralization and content of chemical components in surface water bodies and supraper- mafrost water. Data on the dynamics of the chemical composition and the regime of surface and suprap- ermafrost water in the territory of Yakutsk gained on the basis of long-term observations are presented.

Keywords

cryolithozone, surface water, suprapermafrost water, inundation, macrocomponentsmicrocomponents, cryopeg.
