This paper presents the results of study of the vegetation cover in the North Baikal and the Upper Angara basins. The vegetation mapping was carried out in a scale 1 : 200 000 using the field and archive data as well as GIS-technologies. The structure of the map legend was based on the principles of multi-stage vegetation classification developed by V.B. Sochava.
The vegetation map shows the basic structural-coenotic diversity of the vegetation cover of the study area. Due to the high disturbance of forest vegetation special attention was paid to structural-dynamic analysis to identify potential plant communities. The rows of transformation were estimated as well. The map provides a possibility to make a prognosis for further vegetation successions under the natural and anthropogenic influences.
The approaches and natural preconditions of territorial differentiation of recreational activities within the boundaries of Baikal natural territory (Buryat republic) are considered in the article on a landscape basis. The intensity of tourism development in different landscapes should correspond to their resistance to recreational loads. The integral estimation of stability was calculated in qualitative categories on the basis of a combination of indicators of average and minimum componentwise stability, taking into account their importance in recreational action and the presence of component stability zero values. The low-mountain pine, larch-pine and cedar-larch landscapes, light coniferous and dark coniferous landscapes of valleys, as well as arable land are characterized by the highest indicators of recreational stability. Goltzy and sub-walnut landscapes, as well as wetlands are characterized by low stability. The map of the landscapes stability to the impact of tourism activities has been created by the method of landscape-interpretation mapping. This map will allow further planning of recreational loads in the Central Ecological Zone of the Baikal Natural Territory (Republic of Buryat).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
