Normalized Difference Vegetation Index (NDVI) was calculated based on GIS data of the satellite system ERDAS Imagine, ArcView, ArcGIS to assess pollution of vegetation cover in local rough swamp territories in oil fields under study. Spectral reflectance is a characteristic feature of vegetation and its condition. NDVI values were determined by the ratio of the difference in reflected light intensities in infrared and red regions. The values obtained were corroborated by physicochemical and microbiological analyses of the samples taken in polluted territories during 1999-2007.
