The article studies the landscape structure of the transect polygon in Preolkhon Region, Western Baikal coast. As a result of the research, we have established that the nature of geomorphological processes and the corresponding complex of loose deposits is closely related to differences in solar, circulation and gravitational exposure of slopes. Slope exposure and surface morphology affect the soil cover structure and soil characteristics. Analysis of the distribution of soils in landscapes revealed independent slope exposure series of soils — northern and southern. The plant communities of the southeastern and northwestern slopes differ in their species composition. The change in geomorphological conditions within the slopes of a certain exposure determines a number of plant communities successively replacing each other as the lithomorphism and degree of substrate moisture change. Within the boundaries of the transect polygon, we have been identified 19 facies, the spatial distribution of which reflects the main patterns of differentiation of the Preolkhon Region landscapes, caused by micro- and mezoclimatic differences in exposure position, distance from Lake Baikal, surface morphology; the peculiarities of the manifestation of the leading geomorphological processes and the differences in the reaction of rocks to their impact; lithological heterogeneity of the underlying surface.
