Abstract
Salinity of irrigated areas is one of the environmental problems affecting the sustainable development of arid regions in the north-western part of Uzbekistan. Especially in the irrigated areas located in the Aral Basin, the amount of saline land is increasing year by year, and this, in turn, has a negative impact on the country's agricultural development. A decrease in the amount of annual precipitation and an increase in the annual temperature are leading to the deterioration of the land reclamation of irrigated areas. Therefore, determining and evaluating the salinity of irrigated areas in arid regions is of great scientific importance. In the research work, soil salinity was studied in the irrigated fields of Xo‘jayli district of the Republic of Karakalpakstan during 2011-2022. Traditional methods and GIS technologies were used to evaluate the obtained results, correlation analysis was performed based on long-term data of climate change and its effect on soil salinity was studied. The results of the research revealed that soil salinity depends on the climatic factors of the district.
