Abstract
The article presents data about of the adventive component of the flora of the Kemerovo region, which differs from other subjects of the Asian part of Russia with the highest population density and is a region of intensive development. It is noted that the beginning of the introduction of alien species into the territory of the region through human activity can be considered by the XVII century. A group of archaeophytes is indicated for this period. For the territory of the Kemerovo region, the boundary between archaeophytes and neophytes can serve as the XVIII century. The most significant anthropogenic influence on the vegetation cover of Kuzbass began in the 20th century. It was established that the alien component of the flora of vascular plants is 338 species of 224 genera, 80 families. The largest foreign species and genera of the family are noted: Asteraceae, Poaceae Fabaceae, Brassicaceae, Lamiaceae, Boraginaceae, Caryophyllaceae, Chenopodiaceae. For each floristic area, the number of alien species is indicated, as well as the “original” alien species, noted so far only in this area. It is proposed to supplement the list of invasive species of Kuzbass with 15 species. It has been established that among the alien species of Kuzbass xenophytes, therophytes, one-two-year-old summer-green grassy rod-rooted monocarpics predominate. Geographical analysis of the adventitious flora showed that the enrichment of the Kuzbass flora with alien species was multidirectional.
