Abstract

The use of satellite data for analyzing the dynamics of values of vegetation indices for vegetation of the territory of the Myldzhinskoye hydrocarbon field of the Kargasoksky district of the Tomsk region is considered. Based on MODIS satellite data (Moderate Resolution Imaging Spectroradiometer), the time series of the Enhanced Vegetation Index (EVI) were calculated. Annular zones relative to the Myldzhinskoye hydrocarbon field with radii of 10, 20, 30 and 40 km have been constructed using the ArcGis geographic information system. The average values of the EVI index for each of the constructed zones were calculated. The results of the evaluation of the long-term dynamics of the EVI vegetation index showed a specific index of seasonal cyclicity for the ‘internal’ zone (radius 10 km) of the Myldzhinskoye hydrocarbon field of the Tomsk Region. Seasonal cyclicity in this area is characterized by a reduced length of vegetation period for plant communities.
