Model polygons located in dry subhumid, semiarid, arid and extra-arid climactic zones in Russia and Mongolia were considered for the investigation of vegetation dynamics.For these polygons plots of the NDVI temporal variation and NDVI maps of its spatio-temporal dynamics on the basis of Landsat TM imagery were constructed.The full-scale landscape indication of the selected NDVI areas was conducted.This indication is supported by the analysis of vegetation by environmental groups for drought resistance.The vegetation digression during this period is traced across almost the entire territory of the selected polygons.
