摘      要：The Karakoram Mountains are well known for their widespread surge-type glaciers and slight glacier mass *** the one hand,glaciers are one of the sensitive indicators of climate change,their area and thickness will adjust with climate *** the other hand,glaciers provide freshwater resources for agricultural irrigation and hydroelectric generation in the downstream areas of the Shaksgam River Basin(SRB)in western *** shrinkage of glaciers caused by climate change can significantly affect the security and sustainable development of regional water *** this study,we analyzed the changes in glacier area from 2000 to 2016 in the SRB using Landsat TM(Thematic Mapper)/ETM+(Enhanced Mapper Plus)/OLI(Operational Land Imager)*** is shown that the SRB contained 472 glaciers,with an area of 1840.3 km2,in *** glacier area decreased by 0.14%/a since 2000,and the shrinkage of glacier in the southeast,east and south directions were the most,while the northeast,north directions were the ***-covered area accounted for 8.0%of the total glacier *** estimated elevation and mass changes using the 1 arc-second SRTM(Shuttle Radar Topography Mission)DEM(Digital Elevation Model)(2000)and the resolution of 8 m HMA(High Mountain Asia)DEM(2016).An average thickness of 0.08(±0.03)m/a,or a slight mass increase of 0.06(±0.02)m w.e./a has been obtained since *** found thinning was significantly lesser on the clean ice than the debris-covered *** addition,the elevation of glacier surface is spatially heterogeneous,showing that the accumulation of mass is dominant in high altitude regions,and the main mass loss is in low altitude regions,excluding the surge-type *** surge-type glaciers,the mass may transfer from the reservoir to the receiving area rapidly when surges,then resulting in an advance of glacier *** main surge mechanism is still unclear,it is worth noting that the surge did not increase the glacier mass in this study.
