Short summary
This study evaluated trends in vegetation cover and phenology dynamics in the Inner Mongolia grassland by applying a normalized difference vegetation index (NDVI) time series obtained by the Terra Moderate Resolution Imaging Spectroradiometer (MODIS) during 2002–2014. The positive trends of the cumulative annual NDVI (77.10%) could be interpreted as an increase in plant productivity in the Inner Mongolia permanent grassland. And the growing season has lengthened by 10.86 days.
