摘要： 过量17O是当前水体稳定同位素研究的前沿领域，在极地雪冰研究中备受关注。本文系统地介绍了水循环过程中过量17O研究的基本原理和实验方法，在此基础上，重点评述了极地雪冰中过量17O研究的最新进展，包括过量17O的影响因素、空间分布特征、季节变化、末次冰盛期-全新世过量17O演化特征，并针对极地雪冰过量17O研究尚未解决的科学问题对未来的工作进行了展望。

Abstract: 17O-excess is a new frontier of water stable isotope studies , which has been drawn attention to over polar regions. This paper first systematically introduces the basic principle and experimental method of 17O-excess in the hydrological cycle. And then the latest research progresses of 17O-excess in snow/ice over polar regions, including the influence factors, spatial distribution, seasonal variations, and the last glacial-interglacial evolution of 17O-excess records in ice cores, are summarized. Finally, the future work on 17Oexcess is prospected based on the existing scientific issues in respect of 17O-excess.

Key words: polar regions, stable isotopes, 17O-excess in snow and ice
