Spatio-temporal characteristics of vegetation cover of arid and semiarid climatic zones in mongolia on the basis of vegetation index NDVI

摘要

Model polygons located in arid and semiarid climactic zones in Central Mongolia were considered for the investigation of vegetation dynamics. For these polygons, plots of the NDVI temporal variation and NDVI maps of its multi-temporal values 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.
