- Аннотация: The analysis of the hierarchical organization of the raised bog surface (Tverskay oblast) was carried out on the basis of transect tacheometric data (1 m) and the SPOT6 image (1.62 m). The spectrum was determined using the Fourier transform. Approximation of the spectral density (SP) from period (P) is carried out according to the formula logSP =a-b*log(1/P). Fractal dimension (FD) is FD=(d-b)/2 (d is 7 for surface and 5 for transect). Spectral analysis of the SPOT6 image showed the existence of periods in which an increase in the spectral density in the spectral residuals with its fractal dimension of 2.22, which reflects a not significant increase in the amplitudes of the reflection values with the growth of the period. Thirteen main periods with an increased spectral density are identified which are the most probable in reflecting the surface of the bog (4 m, 6 m, 9 m, 11 m, 13-14 m, 17 m, 22 m, 27 m, 30 m, 34 m, 48 m, 69 m and 160 m). Analysis of the spectrum for the relief of the bog surface showed in its residues the presence of sixteen periods with a relatively high spectral density (3 m, 4 m, 5 m, 6 m, 7 m, 8 m, 9 m, 11 m, 13-14 m, 17 m, 19 m, 23 m, 27 m, 37 m, 54 - 75 m and a trend from 100 m) with a fractal dimension of 2, which reflects the presence of relief forms for all periods of the spectrum. A comparison of the hierarchical organization of the surface of the bog obtained by reflecting its surface and directly measuring the relief profile shows the presence of nine common hierarchical levels (4 m, 6 m, 9 m, 11 m, 13-14 m, 17 m, 27 m, 69 m and 160 m). This shows a high correlation between the structure of reflection and the surface relief of the raised bog. The work was supported by RFBR grant 17-05-00560.
