【 摘 要 】

The results of studies of the group composition of peat organic matter of low-lying deposits of the Northern Trans-Urals sub-taiga zone are presented. It is established that the number of bitumen in the sedge-reed peat of the Ernyakul swamp most often amounts to 6.2-6.8%. In the Usalskoe swamp, their number is in the range of 3.9 to 4.7 percent. The most mobile part of the hydrolysis compounds in the peat from the Ernyakul swamp is 3.4 to 5.5%. In the sedge-reed peat of the Usalskoe swamp, their maximum number (4.1-5.3%) is concentrated in the layer of 0.4 m, the minimum (1.9%) - at a depth of 1.0 m in the hypnum type of peat. 27.0-31.8% of substances, hydrolyzed by 2% HCL, is in the peat of Ernyakul swamp. In the Usalskoe swamp in the meter layer of peat, the average content of this group of substances is by 3.6% more than in the Ernyakul swamp. The minimum amount of humic acids (HA) (30.3%) in peat from the Ernyakul swamp is contained in the sedge type of peat with a decomposition degree of 25%. The number of HA increases to 34.5-35.8 percent with an increasing decomposition degree up to 35-45%. The ratio of HA and FA is 1.6-1.7 with the decomposition degree of peat of 15-25%; with an increase to 35-45%, it increases to 1.9-2.0. The maximum number (32.7 per cent) of the humic acids contained in the hypnum type of peat of Usalskoe swamp is 4.7% more than in the sedge-reed peat. The content of substances, which are difficult to hydrolyze with acids, in the peat of Ernyakul swamp, does not exceed 2.4% and 2.7%. The lowest (1.9%) amount of this group of substances in peat from the Usalskoe swamp is determined in a layer of 0.6 m of sedge-reed peat, the maximum - at a depth of 0.8-1.0 m of the hypnum peat type (3.6%). The amount of lignin in peat from the Ernyakul swamp fits into the interval of 4.5-5.0%, which is 1.5 times more than the cellulose content. The content of lignin in the Usalskoe swamp in the meter layer is 4.2%, which is 3.5 times more than cellulose.
