We considered the main natural features of the geosystem components and conducted a cartographic analysis of the landscape structure of a section of the Malyi Khamar-Daban Range located within the basins of the Temnik river on the northern macro slope (Lake Taglei’s area) and the Torei river (tributary of the Dzhida river) on the southern macro slope of the range. We carried out the landscape analysis and mapping on the basis of the principles of the structural-dynamic geomeric approach developed in the geosystem theory by the Siberian School of Landscape Science. The analysis of the landscape structure was carried out by using manual and automatic processing of spatial information using GIS methods based on Earth remote sensing data, route landscape studies, topographic and thematic maps as well as published evidence. We constructed a physical-geographical profile for a part of the field research route, showing the characteristics of some geosystem components (vegetation, topographic features, soil, Quaternary deposits and pre-Quaternary geological formations). A large-scale landscape-typological map has been compiled, consisting of two parts, which displayed geomers of different scale levels: regional (geoms) and topological (facies). The map legend represents different aspects of structural-dynamic heterogeneity: taxonomic affiliation of geosystems, factor-dynamic properties, seriality and the nature of anthropogenic disturbances in geosystems. The map shows 2413 sections contoured by four geoms, six classes and three groups of facies and 24 facies and their anthropogenic varieties. Four degrees of anthropogenic disturbance of derived geosystems are represented. We identified on the ridge, within the boundaries of the study territory three altitudinal landscape belts that reflect the landscape organization of the geosystems of the study area: mountain taiga (subbelt of watershed-slope larch-Siberian stone pine taiga and subbelt of slope larch taiga), mountain-forest-steppe and foothill-valley steppe areas.
