【 摘 要 】

This study seeks to identify the distinctive features in agricultural land use in the upper (Mongolian) and lower (Russian) parts of the basin. An analysis is made of the main indicators reflecting the economic-geographical characteristics of agricultural land use, the structure of agricultural lands, the level of agricultural development, the dynamics of the area and efficiency of use of croplands, the availability of natural forage lands, and crop yield of grains. This implies a higher yield level of grains and the preservation of the sown area. A decrease in the area of the cropland at the beginning of the agrarian transformations was observed throughout the territory of the basin. In the Mongolian aimags within the Selenga basin, the area of the cropland decreased by 27.5%. In the subsequent period, the sown area remained stable. In the Russian part of the basin, the area of croplands at the beginning of the agrarian transformations decreased by 21.5%. The tendency for a decrease in croplands has persisted to date. During 1999-2016 the area of croplands decreased by a further 25%. The main directions of the transformation of the agricultural land use system in the Mongolian and Russian parts of the basin are formulated.
