【 摘 要 】

Results from investigating the geosystems of Baikal Natural Territory in its western part (Primorskii Range) are presented. For studying macroslope of these mountain range (having an easterly aspect for the Primorskii Range), the regional background and the main factors of the landscape differentiation of the study areas were analysed. Structural features of topological geosystems are revealed, and large-scale maps of key areas are compiled (at a scale of 1:50 000). Maps of the landscape-typological structure were created on the basis of the structural-dynamic and facies analysis of landscapes. Based on of V. B. Sochava's theory of geosystems it is meant for use in processing and ordering a large body of information. It is established that the main factors influencing the landscape diversity are the aspect and steepness of the slopes, the composition and structure of rocks, the absolute height, the amount of atmospheric precipitation, and anthropogenic impacts. It is determined that the influence of the lithomorphic factor is widespread throughout the study areas, the hydromorphic factor is also important, the cryomorphic factor occurs additionally in the goletz zone.
