Abstract:

Glaciers can sensitively reflect the changes of the regional environment that they has become one of the important factors to study the global changes.The glaciers of the Kunlun mountains are concentrated.This area is the ideal one to study glacier dynamic changes.According to the Landsat TM and ETM+ remote sensing images of the year from 1991 to 2009 about the Kunlun moutains,we studied the changes of the glaciers in the recent 20 years.As a result,we found these glaciers changed obviously and concluded that:鈶� The glaciers to the north of the Guozhacuo lake owned the fluctuation pattern from 1991 to 2009;鈶� There existed the difference between the east and west that the changed amount and rate of the east were larger and faster than the west;鈶� About the phenomenon that the Zhongfeng glacier increased largely between the year 2001~2004,we inferred it may correspond to the Ms 8.1 strong earthquake occurred to the west of the Kunlun mountain pass on November 14th,2001;鈶� Combined with meteorological data analysis,we inferred that the changes of the glaciers in this area were synthetically caused by the temperature and precipitation.

Key words: Glacier area change, Remote sensing, GIS, Kunlun mountains
