Abstract
The study was based on the field data collected in the Norilsk industrial area (2001–2004) and remote sensing imagery (1998–2004). The vegetation degradation was assessed using multispectral satellite sensor ENVISAT MERIS. The terrestrial ecosystems dynamics was analyzed using SPOT VEGETATION satellite data recorded at different time periods. The regression models were developed for the Ni–, Cu– and S–containing pollutants allocated in the terrestrial ecosystems components. The vegetation degradation and pollution degree were also estimated using marking system. The area of study was also zoned by vegetation degradation degree.
