| Popis: | The paper deals with the study of the modern dynamics of aeolian processes within the mountain-basin relief of the Khubsugul region of Northern Mongolia and Southwestern Transbaikalia of Russia as exemplified by three key sections of the transboundary region united by the Selenga river basin. These studies are intended to reveal the nature of the development of aeolian massifs of different morphology and location in order to assess the ecological and geographic potential of various territories of the Lake Baikal basin. The study was carried out with a wide use of geomorphological, geobotanical, comparative-geographical methods, as well as the latest methods of remote sensing using unmanned aerial vehicles with the construction of orthophotomaps of aeolian massifs and three-dimensional models of overflying territories. Three key areas-on the eastern coast of Khubsugul, the valley of the Uure-Gol river in the Eastern Khubsugul region and at the western end of the Malkhan ridge (Mankhan-Elysu stow), differing from each other in many natural parameters, are assessed geomorphologically and geobotanically and their comparative geographical analysis was carried out. The current state of the studied sand massifs is estimated by the nature of the dynamics of aeolian processes and a preliminary forecast of their development is briefly given considering the intensity of the existing pasture load and its possible activation by analyzing the structure of the vegetation cover. |
