Abstract
Analysis of vegetation dynamics of the Myldzhinsky oil-producing territory in the Tomsk region using time series of satellite data is performed. All estimates are based on annual time series of Moderate Resolution Imaging Spectroradiometer (MODIS) imagery for growing season from 2015 to 2019. By means of geoinformation system ArcGis, circular zones around the Myldzhinskoye field with radii of 10, 20, 30, and 40 km were built. Average values of the Enhanced Vegetation Index (EVI) were calculated for each of the constructed zones. Analysis of the results showed specific seasonal cyclicity of EVI, in the “inner" zone (10 km diameter) of Myldzhinsky field, which manifests itself in the reduction of the growing season plant communities.
