An analysis is made of the chief causes for degradation of agricultural lands: exhaustive agricultural land use, poor planning quality of land use management, deforestation, low volumes of forest planting and reforestation, and a high degree of plowing of lands. The principles of adaptive-landscape generation and land use practices are substantiated on the basis of a system approach to the exploitation of the natural-resource potential and a package of anti-degradation measures. The structure flowchart is given for the model of adaptive-landscape generation as developed on the basis of assessing the natural-climatic conditions, land resources, the degree of land degradation, and analyzing the set of indicators and criteria for a classification of landscapes. It is found that the key elements of the adaptive-landscape organization of land use on slopes are a typization of lands, the determination of the land use pattern, and the employment of technologies, methods and measures to ensure a normal functioning of agroecosystems. The following groups of lands are identified: gentle near-watershed slopes with a steepness of up to 2–3°; ear-network lands, the lower boundary of which runs along the edge of the hydrographic network, and lands on the hydrographic network. The schematic of the organization of a large balka watershed is provided.Keywords: natural runoff factors, erosion-hydrological process, soil degradation, adaptive-landscape arrangement, agromelioration.
