Abstract

The leguminous plants species diversity (Fabaceae) presented on the territory of Kyrgyzstan was studied in order to clarify their distribution areas according to the types of plant habitats, where the taxons distribution altitudinal pattern was taken into account. Comparative analyzes of all literary information on species, herbarium specimens of plants from the herbarium fund of Osh State University, photographic materials collected during route expeditions about representatives of this family were carried out. Based on the obtained research material analysis and a theoretical background, we were the first to make the following conclusions: in the flora of Kyrgyzstan there are 227 species of Fabaceae, which represent 30 genera, with the exception of species of the genus Astragalus L.; 26 types of plant habitats with soil and relief features were taken into account, taking into account the altitudinal pattern of distribution of taxons in mountain phytocenoses where representatives of this family are found; Genera and certain species have been identified, the representatives of which are characterized by wide, small and intermediate sizes of habitats; groupings of types of plant habitats were discovered on the territory of Kyrgyzstan, which are characterized by the highest, lowest and intermediate indicators in terms of the number of species of leguminous plants; significant differences were noted in the generic and species composition of leguminous plants, types of plant habitats according to the altitudinal pattern of their location; The largest number of species of leguminous plants are found on the territory of the tree and shrub vegetation belt of Kyrgyzstan.
