Popis: | The flora of vegetation cover of sod-lithogenic soil on loess loams was studied at a reclaimed site in the Nikopol manganese-ore basin. The control site is located on the black soil of the steppe area. The species composition of plants was studied in both sites annually for three years. Ecological analysis of the flora was carried out according to Raunkiaer’s system of life-forms and Belgard’s system of ecomorphs. It has been established that the floristic composition on the reclaimed site is significantly poorer than that of the steppe site. The reclaimed site was found to be have fewer species and a smaller number of families. The comparative inconstancy and dynamism of floristic composition on reclaimed soil is shown. The reclaimed ecosystem is distinguished by a significant share of the participation of annual and biennial plant forms. This indicates the anthropogenic transformation of the vegetation cover of the reclaimed soil. Also, a distinctive feature of the reclaimed soil flora is the smaller number of ecological groups of species. Such groups are united according to the ecological optimum to one of the environmental parameters. |
