The paper investigates the quality of vegetation cover and its recovery processes in the zone affected by operations of Solnechnyi mining factory. For over 30 years the company was the largest producer of tin in the USSR. Using VEGA satellite vegetation monitoring service, NDVI dynamics in the study area for the period of 2001–2015 was analyzed. A set of test sites located near industrial sources and at distances from them was selected and examined. The analysis of index values in each test site during the period showed the prospects of self-recovery of vegetation in the affected areas. To get a real picture of the state of secondary vegetation in the impact zone of the factory mining tailings, a dense network of marked ranges were placed on its perimeter and along compass directions at step intervals of 200 m. The results of satellite monitoring were compared with data on formation of secondary phytocenoses obtained during field works by researchers of Institute of Mining FEB RAS until 2005. Alongside with known technogenic factors, natural and climatic conditions were revealed that influence demutation processes positively or negatively, also reasons for slow vegetation recovery were determined.
Keywords: natural and mine technical system technogenesis, NDVI, service "Vega" self-healing vegetation.
