Abstract:

One of the important tasks of reclamation activities is activation of the natural regeneration or purposeful formation of environmentally sustainable artificial ecosystems that are valuable in economic, environmental, and esthetic terms.

Purpose. To assess the reclamation quality of the mining area of the Vilnohirsk Mining and Metallurgical Plant to predict the potential for restoring the ecological functions of the technologically disturbed ecosystem. The object of the study was the reclaimed soils of Vilnohirsk Mining and Metallurgical Plant, for which the basic physical and chemical characteristics were studied based on the established procedures; the results are presented in the form of schematic cartograms of the thickness of the humus layer and underlying rocks.

Methodology. To implement the ecological direction of reclamation of mining territories, a landscape-ecological approach is used, taking into account the need to improve the environmental condition of the area by arranging agricultural land or forest plantations, ordering the territory for recreational needs. For the purpose of soil agrochemical study, soil samples were selected for agrochemical analyses, such as humus content, water extraction, particle composition, and soil moisture.

Findings. The results of the study demonstrated that during the technical stage of land reclamation of Vilnohirsk Mining and Metallurgical Plant, an artificial soil was obtained similar in its physical and chemical characteristics to the natural zonal middle-loamy chernozem on loess-like subsoil that existed within this site before mining operations were carried out. Although this reclaimed soil is somewhat less fertile, it can be used for afforestation purposes. The absence of topsoil salinization indicates the similarity of its main physical and chemical characteristics to the zonal virgin chernozem. Thus, the technical stage of reclamation of this site was performed at the appropriate level. The reclaimed soil was characterized by physical and chemical properties positive from an environmental point of view (no salinization, humus content value, physical properties). It can be predicted that forest woody species planted in the future on this site will contribute to naturalization and ensure the sustainable development of the newly formed artificial ecosystem.

Originality. It is proposed to take into account the environmental conditions suitable for soil biota development when assessing remediation quality. These animals make a significant environmental contribution to positive transformation of soil ecological features.

Practical value. The performed scientific work is a part of current integral ecological task on providing a human with a set of material and intangible services – natural resources and healthy environments.
