The article presents data on changes in the state of the lakes of the Kamyshlovsky Log of the Omsk region based on spatio-temporal data of satellite images and analysis of the chemical composition of water. It is shown that the sodium sulfate type of water in the lakes of the region is formed in the foci of continental salinization – in the Kamyshlovsky Log. It is shown that the decisive role in the formation of lakes is played by their feeding with groundwater enriched with sodium chlorides. The data of the spatial-temporal analysis of the lakes of the Kamyshlovsky Log indicate the course of the process of salinization in the period from 2016 to 2020. Chlorides are of decisive importance in terms of chemical composition in lakes, the type of salinity in all lakes is sulfate-chloride. The exception is Kamyshnoye Lake – according to 2016 data, the type of salinity in the lake is sulphate, which by 2018-2020 was replaced by sulphate-chloride. The soil cover is mainly represented by soils of the saline range, mainly salt marshes, near Lake Piketnoe – solonets, near Kamyshlov – lugovo-chernozem saline saline soil. The type of salinization in the presented soils is sulphate.
Key words: Kamyshlovsky Log / mineralized lakes / soil cover / spatio-temporal data analysis
