Ecologyсal-taxonomic structure of wood and shower plants of industrial pads of PJSC «Central Iron Ore Enrichment Works»

Abstract

The article is devoted to shrubs and plant groups in the territory of the industrial sites of PJSC «Central Mining and Processing Plant». The material of this work was collected in the growing season 2017-2018 years on the territory of the central industrial site and industrial sites №2 Gleuvatsky Quarry, the Giant mine, Artemivsky Quarry, Petrovsky Quarry, mine them. Ordzhonikidze, sludge workshops, which are separated in space and placed at a certain distance from each other separated in kind. The studied tree and shrub communities were formed with the participation and maintained by the person in a satisfactory condition. In the course of itinerant field investigations the species belonging to trees and shrubs were determined. In the future, on the basis of the ecomorphic characteristics of the species, comparative ecological-taxonomic spectra of tree-shrub plant communities of industrial sites were constructed. As a result of researches it was found out that the tree-shrub groupings of the industrial sites of PJSC «TSGZK» consist of 96 species of higher plants belonging to 28 families. Gymnosperms account for a small fraction of taxonomic spectra. Within the sites there is considerable variability in the number of species and families. The most numerous are the families Rosaceae, Salicaceae, Aceraceae. Families of Aceraceae, Rosaceae, Fabaceae, Hippocastanaceae, Oleaceae, Salicaceae, Ulmaceae, Pinaceae are represented by species at all industrial sites of PJSC «CMPP». Only within the Ordzhonikidze mine site are species of the Berberidaceae, Paeoniaceae family occurring, and within the Gleevatsky Quarry site, there are Cannabaceae families. In the taxonomic spectra of plant communities of all sites, the dominant position is occupied by the family Rosaceae. Monovid families occupy half or more of the taxonomic spectra. By reducing the number of species, families, share of species participation in shrubs and shrubs, the corresponding declines can be constructed. The same series can characterize tree-shrub plant groups by the density of species of trees, shrubs, individuals per unit area. According to the ecological and biomorphic characteristics of the species, the corresponding spectra of bio- and ecomorphs are constructed. Ecological spectra are individual in proportion to the participation of certain ecomorphs for each shrub community of the site. Rows of decreasing species numbers are constructed for each ecomorph. It is established that in tree and shrub plant groups of all industrial sites of PJSC «CMPP» wood life forms with root-root system dominate, vegetatively motionless. In the spectra of ecomorphs, the most numerous are solvants, phanerophytes, mesotrophs, entomophiles. In the spectra of hygro-, heliomorph and diasporax, the composition of dominant ecomorphs changes at the industrial sites.
