There are 6 geobotanical areas and 6 geobotanical districts. Taking into account the types of vegetation, a brief geobotanical description of the regions and geobotanical districts is carried out. The region is characterized by desert, semi-desert, wetland, steppe, meadow, shrub, forest and rock- talus vegetation types. This diversity is associated with vertical zonation, which originates from the lowland and rises to the nival belt. The main representatives of the flora of the region are also indicated. Keywords: Geobotanical zoning, vegetation, plant species, height above sea level In connection with the liberation of Karabakh and East Zangezur region from 30 years of occupation, these and the territories in contact with it are of particular interest on issues related to natural resources and, in particular, floristic and plant diversity (Ibadullayeva, Huseynova, 2021). In this sense, it becomes important to systematize the vegetation cover of the region, which at this stage, for known reasons, is possible through a cartographic inventory (Hajiyev 2007; Prilipko, 1963; Khalilov et al., 2014), literary (Prilipko, 1973) material and limited field research. In Azerbaijan, the main principles of systematization of vegetation cover include floristic, botanical- geographical and geobotanical, zoning systems. These zoning systems have the goal of establishing the geographical features of flora and vegetation cover. V.B.Sochava (1966), E.M.Gurbanov (2021) characterizing the features of geobotanical and botanical-geographical zoning systems, indicates that these systems have the goal of classifying the territory by vegetation cover. At the same time, the territorial structure of vegetation cover comes to the fore, reflecting the relationship of vegetation with environmental factors, and in regions with vertical zoning, zoning is characterized by special specificity and “…. obeys its own laws.” In this work, as the initial stage of inventorying the vegetation cover of Karabakh, we consider the geobotanical zoning of its territory. In our understanding, geobotanical zoning is a generalization of material on the vegetation of a certain territory, taking into account the totality of characteristic or zonal plant communities common in this territory. This takes into account phytocoenotic (combination of zonal and intrazonal types of vegetation, type of geographical landscape, vertical zonality) and floristic characteristics (dominant composition of zonal vegetation or groups of species with the same general distribution associated with a certain territory). In the hierarchical ladder of division, we adopted geobotanical areas and geobotanical districts. By the term “geobotanical area” we mean the leading zonal landscape type of vegetation characteristic of the region, taking into account the height above sea level. In the name of formations, we have chosen ecological-phytocoenotic from existing vegetation classification systems (Neshataev, 2001; Movsumova, 2005; Gurbanov, 2007), since until now, the systematization of vegetation by Caucasian researchers, including
