Analysis of Oreoxerophite Flora within Chechnia

Abstract

The article provides information on xerophilous vegetation and its classification from the point of view of ecology, physiology and morphology. The localization of the oeroxerophyte belt above the forest belt along river valleys and in the arid basins of the republic was noted. The vegetation cover here is complex and consists of numerous microgroups, which differ sharply from each other in their coenotic character, since they develop in arid conditions on mountain slopes characterized by a wide variety of microrelief elements. The belt is not continuous, it is located in spots in a chain of arid basins located between the Skalisty and Lateral ridges; the most significant areas are in the upper reaches of the Sharo-Argun and Chanty-Argun, but it reaches its greatest development within arid basins, occupying all the southern mountain slopes. A classification of xerophytes in the flora of the Russian Caucasus has been developed. The most important representatives of oeroxerophytes of various substrates and plant communities are indicated.
