Remote studies were performed with use of high-resolution images Kanopus-V at 30 test sites, located fairly evenly on the territory of the Arctic zone of Western Siberia. Data were obtained on the number of lakes and their areas in each test site. The number of lakes varied in different test sites from 135 to 1620, and the area of lakes is from 40 m2 to 400 hectares. Changes in the characteristics of the fields of small thermokarst lakes are studied depending on the landscape zoning. Changes in the density of lakes, their total area in the test areas and limnicity in the Arctic and northern subarctic landscapes are on average quite poorly expressed, but when they move to the southern subarctic zone, their values show a significant increase, which may indicate a difference in the intensity of thermokarst processes in different landscape areas.
