GEOBOTANICAL MAPPING OF FORESTS IN THE ALTAI-SAYANIAN MOUNTAIN REGION
The principles of the map «Forests of the Altai-Sayanian mountain region (1 : 1 000 000)» are represented. The map was developed on the basis of satellite images (Landsat-7) and with the use of methodology of hierarchical structure of vegetation. Six high levels of hierarchy related to the vegetation belts and subbelts, bioclimatic and geographic sectors, regional phyto-geographical subdivisions were applied to the map legend including 60 units. All thematic cartographical information was organized in Geographical information system «Spatial organization of the Altai-Sayanian mountain region» developed on the basis of ArcGis 9.0. The problems of small-scale geobotanical mapping are discussed.
