Affected by this and that factor, some ice lakes will burst the banks and cause disasters. Based on the newest TM images, 283 ice lakes of Luozha County in Tibet were initially assessed in this paper. According to their types, scale, distance to modern glacier behind, and distance to residential area and roads, the bursting hazards of the ice lakes were divided into high hazardous, medium hazardous and low hazardous. Finally measures were raised aiming at the high hazardous ice lakes.
