Abstract. The paper focuses on three key areas of the Oka River valley in its middle reaches, with different types of vegetation within ridged floodplain relief and pine forest plantation on a complex of floodplain terraces (from Landsat 7 multispectral images). Geomorphological mapping of the key study area became the basis for interpretation of the satellite-generated geodata. Photographic images in the visible and infrared electromagnetic ranges made it possible to determine the unequal contribution of radiation of different wavelengths to the overall spectral pattern of each of the areas. Spectral traces of natural heterogeneity of valley landscapes and complexes of fluvial and lake-alluvial-eolian relief at the local level were established. This revealed some changes in the distribution of infrared radiation channels in the biocenoses of the studied area during the spring and summer of 2016.

 

Keywords: remote sensing, multispectral analysis, Oka River valley, biocenosis, fluvial relief, geomorphological mapping.
