Abstract
The dynamics of the state of vegetation cover has been analysed in the hydrocarbon deposits of the Tomsk region, specifically Luginetskoye, Katylginskoye, Olenye, Lomovoye. The territory of the Oglatsky Nature Reserve was chosen as the background area. Based on satellite data from Terra/MODIS (Moderate Resolution Imaging Spectroradiometer), the average values of the NDVI vegetation index (Normalized Difference Vegetation Index) were calculated from June, 26 to July, 11 for the years 2012 to 2022. It has been found that the same trend in NDVI values is observed for the vegetation in the studied oilfields Luginetskoye, Katylginskoye, and Olenye: the maximum NDVI values were recorded in 2016, while the minimum values occurred in 2012. For the territory of the Lomovoye oilfield, the highest NDVI value was established in 2022, with the lowest in 2012. Overall, a positive trend in NDVI values was noted across all studied areas, with an average increase by 9.7 % from 2012 to 2022, indicating a stable (not suppressed) state of the vegetation cover of these territories.
