The Glacier inventory of China is the basal data for studying glacier changes. An update of The Glacier inventory of China is necessary, because glaciers in the Northwest China have undergone visible changes under climate warming during the past decades. In this study, the ASTER images are used to investigate the glacier changes in the Muztag Ata and Kongur Tagh. The methods of Crisp, Threshold of a ratio image from ASTER band 3/band 4 and manual interpretation are used to map glacier extent and discriminate glacier zones. The debris-covered glacier zone is classified by overlay DEM and images. The parameters are calculated with semi-automatic and manual approaches to compile the glacier inventory. A comparative analysis performed for glacier area shows that there was area shrinkage of 67 ^89 km 2 from 1962/1966 to 2001, accounting for about 6 ^2±1 ^0% of total area. It is demonstrated that it is possible to monitor the dynamic changes of glaciers expediently and rapidly, and to reveal effectively the characteristics of glacier changes by using RS and GIS.
