Abstract

The study of the main factors causing erosive degradation of soils, the study of changes in soils under the influence of water erosion, and the modeling of existing and potential water washout of soil horizons determine the relevance of the conducted research. Analysis of morphologicalfeatures of degraded soils, laboratory analytical studies of their physical and physico-chemical properties, and with the help of GIS tools, modeling of soil washing under the influence of water erosion was carried out. The analysis of studies and publications on the analysis of the main factors that cause erosive degradation of soils, functional analysis and the implementation of modeling of soil washout under the influence of water erosion with the help of GIS tools showed that the issue of changes in background soils under the influence of water erosion and modeling of existing and potential water washout of soil horizons have received little attention in the scientific literature.The purpose of the article is a detailed study of the properties of gray forest, turf-carbonate and meadow soils, as well as the study of erosion processes within the studied territory.Cartographic and descriptive materials of the structure of land use in different years within this model area were studied, which made it possible to analyze the impact of approaches in land use on the intensification of water erosion and the degree of washing. Field and laboratory-analytical studies were conducted to study the morphological, physical, physico-chemical properties of the studied soils. A set of GIS maps has been developed. A 3D terrain model was created to determine the long-term average soil loss due to water erosion under a certain vegetation cover and with a certain tillage system, design and implementation of soil protection measures.For the first time, erosion processes are studied in the territory of the district in a temporal and spatial context. The obtained research results are a significant contribution to the development of the practical foundations of regional soil science. They are proposed to be used for improvement of soil diagnostics and classification; to develop measures to preserve and improve soil fertility; their protection from possible anthropogenic influence.
