Biodiversity of the meadow floristic complex of the ridge Ketpen-Temerlik

Abstract

This article presents results of long-term studies of the meadow flora of the Ketpen-Temerlik ridge within Kazakhstan and China.  The article presents an analysis of the meadow floristic complex of the Ketpen-Temerlik ridge. The taxonomic diversity of species composition of meadow floristic complex, biomorphological analysis of life forms of meadow species, and also the belonging of meadow species to different geographical types of areas. A detailed floristic analysis of meadow flora made it possible to identify 624 species of vascular plants belonging to 230 genera and 47 families. According to the main taxonomic groups of plants, the meadow flora is represented by the Magnoliophyta department, which accounts for 82.2% of the total species composition, and only an insignificant percentage is in the Liliopsida department, 17.1%. The ratio of monocotyledonous and dicotyledonous plants in meadow flora is 1: 4.8. The total number of monocotyledons covers 107 species or 17.1% of the total number of species, there are 517 species of dicotyledonous plants or 82.2%. Analysis of the largest families of meadow flora made it possible to identify 16 largest families by the largest number of species, which contain 504 species. Analysis of the species richness of the genera of

flora are: Potentilla, Carex, Ranunculus, Taraxacum, Astragalus, Silene, Veronica. The leading genus of meadow flora accounts for 25.1%. The article considers a boreal nature of the meadow flora.  The article reveals a large presence among the meadow flora of Ketpen-Temerlik of mountainous middle asian species with an area limited to the territories of Mountainous Middle Asia.
