Krylov Y. Meliorative properties of oak forest in ravine-gully systems of the central part of the Dnieper Upland

The thesis is devoted to research and analyze the protective forest plantations in ravines and gullies of the central part of the Dnieper Plateau. An analytical review of the literature on the study of the properties and characteristics of land reclamation growth plantations that prevent soil erosion and flushing, help curb the formation of cliffs and ravine-balance the beam landscapes. Based on research of ravine-gully oak stands of central Dnieper Upland it's proved the ability of protective forest plantations to counteract water erosion. It's researched a number of meliorative properties of protective forest plantations, including: hardness and permeability of soil, meliorative properties of forest litter, erosion control role of root systems, agrochemical properties of soil, the distribution of snow and moisture reserves in it, soil freezing etc. The features of growth plantations on eroded lands have been researched. Found that protective forest plantations on ravine and gully lands perform their functions completely accumulate runoff and convert it into the soil.
