Перевод заглавия: Temperature gradients in technogenic soils at overburden dumps
Аннотация:As the title implies the article presents the results of studies of the structural organization of technogenic ecosystem soils of industrial zone of Krasnoyarsk and overburden dumps of the Borodino brown coal mine. Based on the results obtained during radiometric surveys in the thermal range, various functional horizonts and vertical temperature gradients of technogenic soil: abrazems in the territory adjacent to the Krasnoyarsk Aluminum Plant, lithostrats and replantozems with different ages and with different types of culture were established. It is revealed that the thermal properties of technogenic soils on overburden dumps of the Borodino brown coal mine, in particular, temperature gradients, during the development of the phytocenosis, change to a greater degree on dumps without fertile soil layer. An increase in temperature gradients leads to an increase in moisture and mass transfer, i.e. to the intensification of the process of soil formation at the boundary of the organogenic and mineral horizons. Moisture and organic matter dissolved in it move towards colder areas, thus increasing the thickness of the humus horizon. In the mineral part of the profile, the temperature field is more stable. Regarding the temperature of the soil surface (T0), the gradients in the organogenic and upper organic-mineral horizons of technogenic soils in the overburden dumps are 7-10%, in the underlying mineral horizons this figure drops to 1-2%. In abrazems in the area adjacent to Krasnoyarsk Aluminum Plant, the values of gradients in the upper part of the profile (0-5 cm) are 8-11% of T<sub>0</sub>, lower in profile down to an average of 5-7%. The variability of gradients rises greatly, which due to the complexity of the structural organization of soils in the industrial zone under study.
