Abstract. The current state of agrosystems that dominate the area in the landscape of the forest-steppe and steppe is characterized by its weak stability and falling productivity as a result of water erosion of soils. Forest amelioration arrangement of agricultural land can significantly reduce the processes of surface washout of soils, the fall of their fertility, the growth of ravines. The protective plantations acquire special importance in connection with the transition to a green economy, the development of the farmer’s movement, the growing pollution of the environment and the anticipated changes in the global climate. The article contains the economic classification of the numerous spectrums of service functions of the runoff-regulating forest belts on the sloping plow land. With reference to different natural and climatic conditions of the South of the European territory of Russia, an assessment of the total ecological and economic effect obtained from the afforestation of erosion-hazardous agrolandscapes is presented. The amount is determined, the regularities of its orographic and zonal dynamics are established. The expediency of forest reclamation measures in areas prone to water erosion is proved. It is established that the spatial effects from the influence of forest belts on the adjacent territories are mainly due to the slope of the terrain and the degree of soil washout, the local utility is strictly dependent on the quality of the soil-climatic conditions (natural zone) and the bioengineering parameters of plantations. The agricultural development of sloping lands with the creation of runoff-regulating forest belts on them is of great importance for the economy due to the greening of the industry and the increase in the gross regional product. The systematization of benefits from anti-erosion forest amelioration of the territory and the resulting assessments will significantly improve the effectiveness of management decisions on the need and appropriateness of afforestation of sloping arable land to improve the conditions for conducting agricultural production and improve the quality of life of people in Russian regions with erosion risk in the short and long term. 
Key words: erosion-dangerous regions, slope, plough lands, forest amelioration, service functions, total effect, locality incline, natural zone, tree stand, life time.
