Vertical zonation of the north Anabar plateau mountains: division to belts using geospatial analysis methods and analysis their partial floras

The analysis of the altitude distribution of vascular plants in the north Anabar Plateau (Taimyr, Russia) is carried out. The existing approach to the evaluation of the vertical zonation of flora and vegetation was analyzed and the proposed modification was proposed. Using GIS analysis, allocated 6 high-altitude zones, for which partial flora (PF) revealed.The taxonomic, geographic, ecologo- coenotic analysis PF is conducted. It is found that the nature floras on the altitudinal gradient varies from Hypoarctic to Arctic type. 10 groups of plant species in character their altitude distribution was identified - from occurring at all altitudes (ubiquity) to groups found in one or two zones. For each of these groups geographic and ecological-coenotic structure was briefly analysed. As it turned out, ecological-coenotic analysis differentiates PF vertical belts most markedly.
