Abstract: Currently, one of the effective means in monitoring glacier change in regional scale is remote sensing and site-observation method. In this article, we present a study of comparing glacier area in 2005 derived from SPOT5 satellite image with area in 1972 derived from topographic maps. Moreover, Miaoergou (庙儿沟) flat-summit glacier is site observed to verify glacial change in regional scale. During the study period, glaciers located in the southern slope of Kalik (喀尔里克) Mountain reduced their area by 12.3%. The high individual change indicates that the wastage corresponding to area changes has been the dominant process of glacier mass loss in this region. Glaciers smaller than the mean size (1.3 km2), especially those <0.5 km2, lost more of their area with high variability and yielding two glaciers vanished. It is suggested that small glaciers are prone to disappear under such climate conditions in future years...
