Phytomeliorative Recovery In Reduction Of Multi-element Anomalies’ Influence Of Devastated Landscapes

Abstract

V.V. Popovich

Formation of soil anomalies in the operation area and the mine waste dumps results in an accumulation of heavy metals in plants, particularly if the physic-chemical properties of soil to facilitate the transition elements available to form them. We have proved that the individual organs of plants have a high capacity for accumulation of heavy metals, which allows us to recommend them for landscaping of dumps and heaps like plants, is actively contributing to the stabilization of technologically impaired environment under conditions of significant contamination. It should be noted that an embodiment of the ecological stabilization of anthropogenic disturbed territory, on which the landfills and waste dumps of coal mines, is the introduction of individual plant micro associations that will be investigated in more detail in our further work on the technologically impaired phytomelioration territory. Despite the fact that the overgrowth of dumps and heaps helps to improve the environmental situation, the number of pollutants, including heavy metals, hydrosphere and lithosphere remains high. This is due to the fact that the soil is able to deposit the contaminants and can be long-term source of secondary pollution. We proved that that dumps and heaps of coal mines led to an increase of industrial hazard in the region based on the research of background radiation, heavy metals contamination in edaphotopes and vegetation. We also studied the species diversity, the stage of overgrowing, distribution of individuals in the vegetation communities in devastated landscapes. Analysis of our research results testified the necessity of protective trees shield within devastated landscapes to improve the ecological condition of industrial congested region and increasing the productivity of disturbed lands.
