根据乌鲁木齐河源１ 号冰川冰芯δ１８ Ｏ 记录与大西沟气象站实测的气温资料， 进一步系统地探讨了所研究区域冰芯δ１８ Ｏ 记录的气候意义。结果表明，冰芯δ１８ Ｏ 记录与夏半年（５月～１０ 月）平均气温之间存在一定程度的正相关关系，而与冬半年（１１ 月～次年４ 月） 平均气温不存在稳定的相关性。该结果拓展了中、低纬主地区山地冰川冰芯δ１８ Ｏ 记录作为温度指标的适用性。
According to the δ18O records of glacier ice core 1 of Heyuan source in Urumqi and the measured temperature data of Daxigou meteorological station, the climatic significance of δ18O records of ice cores in the studied area is further systematically discussed. The results show that there is a certain degree of positive correlation between δ18O record of ice core and the average temperature in summer (May-October), but not with the average temperature in winter (November-April) Sex. This result extends the applicability of the δ18O record of glacier ice core in the middle and low latitudes as a temperature indicator.
