TAXONOMIC STRUCTURE OF THE PLANT COMMUNITIES OF TREE PLANTATIONS AT THE IRON ORE DUMPS IN KRYVYI RIH CITY

The development of woody-shrub vegetation in dump ecotopes for a long time was considered as the perspective of phytorecultivation problems. As a result of preliminary studies of the Department of Optimization of Technogenic Landscapes of the Kryvyi Rih Botanical Garden of National Academy of Sciences of Ukraine, it has been established that optimal conditions for its development are created in the dump ecotopes, firstly, at a certain level of moisture and mineral nutrition, which corresponds to a range of a number of hygrotopes: from dry to fresh (clays), from dry to wet (loams), from wet to very wet (sands), from raw to wet (gravel and screes) and wet (pebbles and gravel)
