EFFECTS OF MINING, THERMAL, INDUSTRIAL PLANTS ON FORESTS LAND AND REHABILITATION PRACTICES IN THE URAL REGION IN RUSSIA

Abstract

The purpose of this study is to develop the scientific basis for the optimization of post-technological areas and practical recommendations for reforestation on land contaminated with industrial waste. The Urals with its most powerful mining, metallurgical and chemical industries is one of the centers of research on the development of scientific bases for the rehabilitation of disturbed lands. So, in this study it was focused on effects of some plant in Ural Region. Objects of research include three types of disturbed lands: 1) Ash dumps of thermal power plants working on coal - reclamation of the ash dump at Reftinskaya GRES-Sverdlovsk region, 2) Forest restoration on lands contaminated with industrial waste - in the zone of action of Satkinsky Combine Magnesite, 3) Territories contaminated with non-ferrous metal waste products - sulfur dioxide plus heavy metals in the Karabashmed area, Russia. It was found that the study of the dynamics of transformation of forest plant communities and the ability of self-purification of biogeocenoses in the gradient of pollution in terms of reducing emissions takes a special place in the assessment of the negative impact of anthropogenic stress on the stability of forest ecosystems.
