摘要
９９７年中美联合考察队对珠穆朗玛峰绒布冰川考察期间，采用ＧＰＳ技术对冰川末端位置进行了测量．将其结果与１９６６年考察测量的位置对比得出，过去３０ａ间该冰川末端后退了１７０～２７０ｍ，平均年退缩量为５５～８７ｍ．由于目前气候仍在变暖，该冰川将继续保持退缩状态．
During the Sino-American Expedition to Mt. Qomolangma in 1997, the Rongbuk Glacier was investigated and its terminus location was measured by means of GPS techniques. Comparison with 1966′s measurement yields that in the past 30 years the glacier has retreated 170～270 m, equivalent to a retreat speed of 5 5～8 7 m/a. This suggests that climate in the region has mainly been in warming since the early part of this century, because glacier response to climatic change has a retardation. Due to climatic still warming in recent ten years, the glacier retreat will continue for several decades.
