Annotation:  The article assesses the state of forest belts and the development of a gully network in the Vezelka river basin of the Belgorod region. The availability of reliable material multi-temporal planned surveys in the Vezelka river basin – made it possible to analyze the change in small forms of the erosional landscape, the state and effectiveness of protective forest plantations. We used topographic maps of 1955 with a scale of 1:10000, modern satellite images of 2018, with a spatial resolution of 1.5 m/pix. The study was conducted using the software package ArcGIS, as well as using the methods of comparative, cartographic and comparative geographical analysis. It is established that, despite the increase in the density of forest plantations in 2018, the greatest concentration of ravines was in areas not contoured by forest belts. It was revealed that the eastern part of the Vezelka river basin is covered by a thicker erosion network, and the greatest concentration of new erosion forms, including ravines, is also noted there. A significant part of the newly appeared ravines appeared on the slopes, the edges of which were deprived of forest plantations, and also near water bodies not contoured by forest belts. Also, a modern satellite image showed a large number of sites where forest belts fell out.
