The territory of the Baikal region, which, on the one hand, is promising for the development of various types of economic activity, and on the other hand, unique and highly valuable from an ecological point of view, requires scientifically based land use planning. Landscape and physical-geographical scientific studies in the Baikal region were started in the 1960s after the foundation of scientific institutions majoring in natural sciences in Irkutsk. The Siberian School of Landscape Studies was established at the Institute of Geography of the SB RAS, methods for mapping and classifying geosystems at different hierarchical levels, methods for biota mapping, and methods for landscape planning have been developed. At the moment, as an information basis for solving various applied problems, a landscape map of the south of Eastern Siberia (M 1 : 1 500 000), created by V. S. Mikheev and V. A. Ryashin and co-authors in 1977 is used. Employees of the Institute of Geography of the SB RAS in different years created landscape-typological maps of medium scale (1 : 50 000 – 1 : 500 000) for different territories of the Baikal region: Khamar-Daban ridge, Olkhinskoe Plateau, Priolkhonye, Selenga river delta, Barguzinsky ridge. The coverage of the territory of the Baikal region with medium-scale landscape maps and the representation of various types of landscapes in accordance with the map of the landscapes of the South of Eastern Siberia on medium-scale maps are analyzed. The least studied at the local-regional level are the landscapes of the Primorskiy, Baikalskiy and Barguzin ridges. The geosystems of the Baikal region from the most studied to the least are located as follows: Central Asian steppe, South Siberian, goltsy and podgoltsy, Baikal-Dzhugdzhurskiy.
