The impact of transformation in the vegetation and soil cover on the soil temperature regime under winter road operation in Bolshezemelskaya tundra has been studied. Winter, summer and mean annual temperature parameters of tundra peat and mineral soils were revealed at the road section in the North Khosedau oil field. The main differences in the temperature regime of upper soil horizons (0–40 cm) at anthropogenically disturbed (tracks of the winter road) and undisturbed sites in different tundra ecosystems affected by continuous permafrost have been revealed.
