世纪初，北方半球经历了最热的气温，这明显增加了青藏高原冰川的融化。本研究分析了该地区的冰川变化，他们的终端位置和表面海拔在过去十年（2003年至2013年）在西喜马拉雅山的Naimona'Nyi地区，通过比较遥感数据和差分全球定位系统（dGPS）数据从situsurveys。结果显示，在过去的十年里，该地区的冰川正在加速退缩。在这一时期，冰川覆盖的面积减少了1/3。本文研究的Naimona'Nyi主冰川的终点退缩了超过。我们还比较了冰云和高程卫星高程数据与dGPS高程数据，从而提供了不同时期冰川表面高程的变化。2009年至2013年间，冰川最大减薄率达到了5.5%。除了对海拔和冰川大小的依赖外，我们还发现该地区北向斜坡的退缩比南向斜坡的退缩要大。气象资料表明，研究区域内的冰川变化可能归因于观测到的快速升温。
The Northern Hemisphere experienced its warmest temperatures in the early 21st century, and this clearly increased glacier melting on the Tibetan Plateau. This study analyzed the glacier change in the area, their terminus positions and surface elevations over the last decade (2003 to 2013) in the Naimona’Nyi region of the western Himalayas, by comparing remote sensing data and differential global position system (dGPS) data fromin situsurveys. The results show an accelerating glacier retreat over the past decade in this region. The area covered by glaciers was reduced by a total ofover this period. The terminus of the Naimona’Nyi main glacier studied in the paper retreated by over. We also compared the ice cloud and elevation satellite elevation data within situmeasured decimeter accuracy dGPS elevation data, thus providing changes in glacier surface elevations in different periods. The maximum measured glacier thinning rate reached tobetween 2009 and 2013. In addition to the dependence on elevation and glacier size, we found a larger retreat on the north facing slopes than on the south facing slopes in the region. Meteorological data show that glacier changes within the study area can probably be attributed to the observed rapid temperature rise.
