ABSTRACT
This work is devoted to the environmental assessment and zoning of the Chaya River basin in Western Siberia using the data of mire water chemical composition and changes in the water level. Investigations showed that the features of the environmental state of the basin are largely determined by the total bogging of the catchment area, as well as by the spread of mires and ridge-hollow-pool complexes and swamp landscapes. Mire waters are characterized by low mineralization. The inflow of low-mineralized water from vast waterlogged interfluvial spaces reduces the flow of ions, enhancing total iron and organic matter flow. In addition, widespread swamp and ridge-hollow-pool bog complexes significantly reduce the intensity of the water exchange of the area, but significantly increase the ecosystem’s stability in terms of anthropogenic stress. In general, high waterlogging of the southern taiga subzone of Western Siberia determines the stability of the hydrological catchment areas in the conditions of the observed climatic changes and the increasing anthropogenic influence.
