Abstract RS data files and GIS technology were employed to monitor the change of sandy land area on Zoige plateau from 1975 to 2005. The results showed that the sandy land area increased by a rate of 0.76% per year in the past 30 years. Especially during the period of 1990s, the increasing rate was the fastest. Besides, it is demonstrated that the sandy land has a regional distribution. Study results also showed that over grazing is the main reason leading to the expansion of sandy land, and the factors of air temperature arising, rainfall decreasing, and heavy wind frequently blowing are the necessary conditions.
