【 摘 要 】

In the early 1990s, Russia and Mongolia started transformations of the land relations and the system of agricultural land use. 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 and crop yield of grains. It was found that in spite of the more severe natural and climatic conditions, the Mongolian part of the basin has higher efficiency of agricultural land use. 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 spite of a significant amplitude of fluctuations during separate years. 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. The main of the transformation of the agricultural land use system are formulated.
