The Mongolian plateau is a relatively isolated territory with arid and semiarid conditions and vast steppe spaces. Ecological changes in the steppe ecosystems affect the environment of northeastern Inner Mongolia in China, and eastern Mongolia. The article analyzes the spatiotemporal distributions of the vegetation cover and plant communities (at the level of facies) based on the Landsat and MODIS13Q1 remote sensing data of Sino-Mongolian transects at typical steppes of the Mongolian plateau in 2002, 2009 and 2016 and with the use of 3S technology. The research results indicate a general tendency to degradation of the vegetation cover macrostructure; herewith, a more serious degradation is observed on the transect of Inner Mongolia in China in comparison with the territory of Mongolia. Differences in plant communities are presumably explained by different methods of cattle grazing.
