The article examined a comprehensive analysis of the modern reclamation state of irrigated lands of Karmakshy District of Kyzylorda region, located in the lower reaches of the Syrdarya River, studied the causes and degree of salinization of soil cover. The territory of Kyzylorda region is located in the Turan lowland. Over the past half century, large changes have taken place in the entire natural complex due to the decrease in the flow of the Syrdarya River in the Aral Sea region. As a result of the drying up of the Aral Sea, a desert with an area of 21.4 thousand km2 was formed in its Kazakh Part. The work was carried out to compile a soil map of Kyzylorda region. When creating a map, we used GIS technologies. By compiling a soil map, we conducted a survey of the soil of Karmakshinsky district. In addition, the soil cover of irrigated lands of Karmakshy District in Kyzylorda region is grouped by types of salinization, the features of their development and distribution are described, and ways to improve the soil-salt regime of irrigated lands are considered.
