摘要：

The specific features of changes in the content and mobility of organic matter in litters and cryogenic soils under heating were revealed. The thermal stability of the organic matter and litters is different. In the soils, the maximal loss of matter was recorded at a temperature of 300 degrees C. In the litters, the maximal losses were found at 300, 400 and 550 degrees C and depended inversely on the carbon content in them. The heating to 200 degrees C caused insignificant changes in the mass of the litters and soils but increased the content of the water-soluble fraction of organic matter and the concentration of the water-soluble mineral nitrogen forms.
