Ecological structure of the city of Kemerovo flora

The article presents the results of the ecological analysis of the flora of higher plants of Kemerovo are presented. The research was carried out by the method of model areas in 2021-2023. Vascular plants of the Kemerovo flora were distributed into appropriate groups according to the scales of optima for species of Western and Southern Siberia [Ilminskikh, 2021; Korolyuk, 2006]. The flora analysis was carried out in accordance with the methodological recommendations of M.V. Schmidt [1984] and B.M. Mirkin and L.G. Naumova [2017] using Microsoft Office and IBIS software packages [Zverev, 2007]. 14 functional zones were identified to analyze the ecotopological structure of the city. According to the main environmental factors, all vascular plants of the Kemerovo flora are divided into groups according to factors: humidity, salinity and richness, illuminance and shading of soils. According to the main abiotic factors, the flora of Kemerovo is characterized as hygromesophytic-mesohygrophytic, mesotrophic and heliophytic-helioscyophytic. It is noted that the flora of the city of Kemerovo differs in more xeric and heliophytic features, compared with the flora of adjacent natural territories. It is established that the urban environment contributes to a significant increase in the number of species growing on poor and slightly acidic soils. A comparison of the ratio of the ecological groups of the alien and indigenous components of the flora demonstrates the introduction of xeric features into the flora of the city by the non-native faction.
