Abstract: Changes in pasture land cover in the Selenge River Basin were processed using Moderate Resolution Imaging Spectroradiometer (MODIS) vegetation spectral indices from 2000 to 2020 at 5-year intervals. The study determined relationships between air temperature, precipitation, population, and number of animals during the growing season of those years. Spatial and temporal changes in Mongolian grassland and hay classification were graphically and quantitatively processed using the Google Earth Engine (GEE) platform and map processing software. Factors influencing changes in plant indices that represent plant growth from June to August were evaluated by correlation assessment. During the study period, the maximum value of NDVI was observed in 2020 and the minimum value was observed in 2000. Considering the average value of them, it was 0.64 in 2000 and 0.7 in 2020. But in 2005 and 2015, the average value decreased to 0.57. When developing the EVI, the average value between 2000 and 2015 was consistent and between 0.33
