英文摘要	Stable oxygen isotope ratios (delta O-18) of three shallow ice cores (extending back to 1963) from Urumqi glacier No. 1 at the headwater of Urumqi river, Tien Shan, northwest China, were used to test the relationship between delta O-18 and contemporaneous surface air temperature (T-a). The ice cores were dated using the seasonal stable-isotopic signals, and seven insoluble particulate beta-activity horizons associated with known nuclear tests. Although a strong positive relationship exists between delta O-18 in precipitation and T at our study site, this relationship is not preserved between the annually averaged ice-core delta O-18 records and the local temperature due to post-depositional modification. These results indicate that the processes forming the ice-core chemical records in areas of high melt must be understood before the delta O-18 record can be confidently interpreted as a climatic indicator.
