摘　　要：Little is known about recent variation of temperate glaciers on the Tibetan Plateau,although they are of particular theoretical and practical interests in terms of climate change and water supply.The study of glacier mass balance and terminus variation for six temperate glaciers in the Parlung Zangbo River basin,southeast Tibetan Plateau,shows the facts of the overall negative mass balance and the continued terminus retreat from 2005/2006 to 2007/2008.The mass balances of smaller glaciers were more negative compared to larger glaciers.Referring the trend of glacier mass balance in the Hengduan Mountains,the Himalayas and glacier shrinkage in southeast Tibetan Plateau,the mass loss and recession of temperate glacier in this region are expected if the current climate condition continues.Little is known about recent variation of temperate glaciers on the Tibetan Plateau, although they are of particular theoretical and practical interests in terms of climate change and water supply.
