Analysis of gypsum-hammad and variegated floristic complex of the Ketpen ridge

Abstract

 This article presents the results of many years of research on the gypsum-hammad and variegated flora of the Ketpen ridge. The paper presents an analysis of the gypsum-gamma and variegated floristic complex of the Ketpen ridge. The taxonomic diversity of the species composition of the gypsum-hammad and variegated floristic complex, the biomorphological analysis of life forms of gypsum-bearing-hammad and variegated species, as well as the belonging of gypsum-bearing-hammad and variegated species to different geographical types of habitats were revealed. A detailed floristic analysis of the gypsum-hammad and variegated flora made it possible to identify 250 species of vascular plants belonging to 132 genera and 32 families. There are 232 species of dicots, 17 species of monocots. The ratio of monocots to dicots is 1:13.6. The numerical ratio of the flora of the gypsum-hammad and variegated floristic complex is 32:132:250. On average, there are 1.9 species per genus. The species saturation of the families of gypsum-hammad and variegated flora is characterized by an average indicator and is 7.2. Analysis of the largest families of gypsum-hammad and variegated flora made it possible to identify 16 largest families according to the largest number of species, which contain 222 species in their composition. Analysis of the species richness of the genera of the gypsum-hammad and variegated flora of the Ketpen ridge shows that out of 132 genera, 8 genera are large (10 or more species). The polymorphic genera of the flora are Zygophyllum, Astragalus, Lappula, Salsola, Caragana, Artemisia, Anabasis, Lagochilus. The leading genera of gypsum-hammad and variegated flora account for 36.8%. Based on the analysis, the desert character of the gypsum-hammad and variegated flora is shown, and a large presence among the gypsum-hammad and variegated flora of Ketpen of mountainous Middle Asian, desert and Ancient Mediterranean species, with an area limited by the territories of Mountainous Middle Asia and the Ancient Mediterranean, was revealed.
