Abstract

The basis for in-depth studies of the southwestern district of the city of Abakan vegetation, the Republic of Khakassia was the lack of information on the current status, structure and species composition of the whole city flora. Targeted floristic studies in the city of Abakan were not conducted. Since the mid-twentieth century, study of plant cover of the Republic of Khakassia was engaged in prominent botany of the Siberian scientific and educational institutions of Siberia, but most of them were passing through the city of Abakan. The study of the flora was held by the honored worker of the Russian Federation Krasnoborov I. M. while working at the Herbarium of Khakass state university (KhSU) and Associate Professor of KhSU T. M. Zorkina. Flora of the South-Western area was identified based on field research expedition model area (MA) within the administrative boundaries of the city of Abakan in 2017-2018, the study of literature data and herbarium materials of the Krasnoyarsk state pedagogical University (KSPU) and Khakass state university (KhSU). Most of the territory of MA have been visited repeatedly and at different times of the growing season, and that suggests the method of urbanized landscape model areas. South-Western residential district of the city of Abakan, (known as the village of MR - Ministry of the Railways), consists entirely of multifamily housing, in 2011 there was a Komsomol Park, which determined the composition and structure of its flora. The taxonomic spectrum of the flora of the southwestern district of the city of Abakan includes 16 families of the world flora, of which only 3 families are with identical ranks: an Asteraceae, Fabaceae, Scrophulariaceae. The taxonomic spectrum of the flora of the southwestern district of the city of Abakan is of Brassicaceae-type, Fabaceae-subtype – extreme-book Mediterranean, which corresponds to the position of the city of Abakan in the steppe zone of Eurasia and belonging to the Boreal floristic region.
