Ynamic Variation of Glaciers in Bomi County of Tibet During 1980∼2010

Abstract Applied by remote sensing (RS) and geographical information system (GIS), an analysis of big glaciers dynamic variation was shown during the past 40 years in Bomi County utilized the meteorological data provided by Bomi Meteorological Station. The results showed that the area of glacier in Bomi County has experienced a general shrinkage in area from 1980 to 2010; it has decreased 25.74km2 in the recent 40 years. Among them, the areas of big glaciers during 1980 to 1990 contribute to 64.6% of the total area loss. The records in Bomi Meteorological Station indicated that the glacier shrinkage was mainly subjected to continuous temperature rise, especially after 1980.
