[Objective] To evaluate effects of graze-prohibited policy implemented in Ordos area.[Methods] Using the the coverage index elicited by two-pixel model from MODIS-NDVI as the data source, to evaluate the spatial-temporal changes of growth seasonal vegetation coverage in no grazing district from 2000 to 2012, and to analyze the annual change using transfer matrix.[Results] The vegetation coverage reduced gradually from east to west, the vegetation coverage in the eastern division was higher than that in the west, the coverage in the north was higher than that in the south. The vegetation cover generally increased from 2000 to 2012, with a changing tendency from low to high vegetation cover. In the periods of 2008-2012, the vegetation coverage was better than that of 2000-2004 and 2004-2008.[Conclusion] The study area had a significant increase in the vegetation coverage, which indicates that the graze-prohibited policy have a great effect on the grassland ecological restoration.
