摘　　要：古里雅冰帽是目前在中低纬度发现的最高、最大、最厚和最冷的冰帽。该冰帽是一个极地型冰川,不仅冰温、冰川性质与极地冰相近,而且冰面气候环境特征也同极地冰盖一样具有明显的空间变化特征。古里雅冰帽还是迄今在中国发现的最稳定的冰川,从末次冰期到现在,冰川只退缩了50多米,这为长时间序列的冰芯气候环境研究,提供了理想的场所。The Sino-American cooperated expeditions were carried out in 1990 and 1991 for future deep ice core researches. The Guliya Ice Cap is the highest, largest, thickest and coldest Ice Cap in all the ice caps found in middle-low latitude regions. Its height is about 6 700 m and total area surpasses 376 km2 with an area of above 100 km2 at the top of the Ice Cap. The mean thickness is over 200 m and the maximum can reach 350 m. The ice temperature measured at the top of Ice Cap is -18.6℃. The Guliya Ice Cap is of polar type glacier. This is showed not only by extreme low ice temperature and glacial properties but also by the apparent spatial change features of the climate characteristic and enviromental characteristics on the Ice Cap, which are both similar to polar ice sheet. The Guliya Ice Cap is the most stable glacier found in China up to now. It has only retreated 50m from the last glaciation to the present and thus provides a ideal site for long time series climatic and enviromental researches by ice core.
