中文摘要	气象和地形条件的复杂使利用山地冰川重建既往气候变化的努力变得困难.通过对西昆仑山崇测冰芯记录中近百年稳定氧同位素delta~(18)O资料分析研究,发现在冰芯资料与塔克拉玛干周围气象台站夏季气温记录在可比的30～40年间存在着显著的正相关关系.据此重建了塔克拉玛干周边地区上世纪前半叶夏季气温变化趋势.在世纪尺度上该区气温呈波动上升趋势,沙漠90余年中夏季气温上升幅度约为1.2℃.
英文摘要	It is difficult, in general, to reconstruct past climatic records for a continental inland region relying mainly on the ice core data from the high mountainous glaciers due to the processes that terribly complicated by the sharp topography transition. However, delta~(18)O data from the Chongce Ice Gap at an altitude over 6000 m a.s.l., and the meteorological log provided by the local stations around 1000 m a.s.l. surrounding Taklimakan Desert have shown a good con-elation, basically in summer temperature, for a compatible period, three to four decades from 1992 back to 1950s. It suggests a close relationship between these two records. Upon a deep analysis on the associ- ating mechanism, this paper tried to establish a formula to extrapolate the temperature sequences to an earlier stage for the desert region depending on the longer delta~(18)O data as covered by the ice core. On a whole, temperature around Taklimakan Desert was rising in the century scale, and the warming trend is about 1.2℃ for the data covered 90 years.
