Water area dynamic change of the Hulun lake was analyzed from 2000 to 2013 using long time-series MODIS data and water index dynamic analysis method. The driving force of the change was also analyzed by combining meteorological data. The preliminary results showed that the water area of the lake decreased from 2286km2 in 2000 to 1773km2in 2012 and the decreasing rate was 22.4%. The drastic changes mostly happened in the northeast and south of the lake. Due to the great increase of precipitation in 2013, the water area restored to 1883km2 and the main growth happened in the south of the lake. The driving force analysis showed the variation of water area correlated negatively with an average annual temperature and positively with the annual total precipitation. However, the level of significance was for the precipitation higher than temperature.
