The purpose is to reveal spatial regularities of ravine erosion development in the Belgorod region. Materials and methods. We used geoinformation modeling in ArcGIS 10.5 software package, which allowed us to create a map of the density and density of the ravine network based on the geodata base of ravines of Belgorod region created by the method of manual vectorization of M 1:10000 tablets. Using the method of spatial clustering, homogeneous types of territory overexposure were found. Results and discussion. It was found that the territories with maximum ravine erosion, occupying 7280 km2 , belong to the central and eastern parts of the region, and along its perimeter there is a zone of average ravine erosion, occupying 5948 km2 ; the western and southern parts of the region are least subject to ravine formation process, and this territory occupies 13901 km2 . Conclusions. The central part of the region is exposed to the maximum impact of ravine erosion. In order to suspend its impact on the landscape should be recommended enhanced erosion control measures, including hydraulic structures of different types. On the rest of the territory the existing erosion control measures are sufficient to restrain the ravine formation process: grassing of drains, anti-erosion crop rotations, afforestation, planting of forest belts.
