据乌鲁木齐河源地区一个完整年周期的大气降水样品、1号冰川连续雪坑样品及浅冰芯样品的实测δ18O资料，初步探讨冰芯δ18O记录的形成过程和影响因素，以及δ18O与气温之间的关系转变。结果表明本区大气降水中的δ18O与气温之间存在显著的正相关关系，但由于冬季雪层内水汽运移作用和风力导致积雪的重新分布作用，以及夏季雪层中融水渗浸作用等积雪沉积后的影响，1号冰川冰芯的δ18O记录与实测气温记录之间存在明显的差异，即研究区域的冰芯δ18O记录不再具有明显的温度指标意义。
According to the δ18O data of a complete annual cycle of precipitation in the Heyuan area of Urumqi, continuous samples of glaciers in the No. 1 glacier and samples of shallow ice cores, the formation process and influencing factors of the δ18O records in the ice core and the relationship between δ18O and temperature Relationship changes. The results show that there is a significant positive correlation between δ18O and air temperature in the atmospheric precipitation in this area. However, due to the water vapor transport in the winter snow layer and the redistribution of snow caused by the wind, After the deposition of snow, there is a significant difference between δ18O record of the glacier ice core 1 and the recorded temperature record. That is to say, the ice core δ18O record of the study area no longer has obvious significance of temperature index.
