Research object: ravines, gullies, barracks of the steppe zone of Ukraine. Research subject: the formation of geochemical barriers at different stages of the development of ravines, beams, and barracks. Purpose of the study: conducting a study of gully-beam systems as geochemical barriers of the steppe zone of Ukraine and determining their ecological significance. Task: - analysis of natural conditions and determination of ravine formation factors; - determination of the regularities of distribution of links of gully systems in the steppe zone of Ukraine by means of GIS; - conducting a cluster analysis and determining the environmental risks of man-made soil pollution in the areas of iron and manganese ore mining; - determination of features of accumulation of heavy metals in soils of different granulometry composition and formation of geochemical anomalies; - determination of indicators of migration of substances and trace elements in relation to the detection of geochemical barriers. Research methods. During the period of work, state standards and complex methodical approaches to conducting field research were applied. Soil samples were taken in 5-fold repetition according to the soil profile. Mathematical processing of the obtained data was carried out in accordance with the requirements of statistical analysis. The concentration of trace elements, including heavy metals (Fe, Mn, Ti, Cr, Cu, Ni, Pb, Cd) in soil samples was determined by atomic absorption spectral analysis. The practical significance of the results of scientific research work in determining the role of gully system in the formation of the steppe, the creation of geochemical barriers, and the preservation of unique steppe biogeocenoses.
