摘要：

目前，位于东南极冰盖分冰岭中心的冰穹-Dome A已成为深入理解南极冰盖演化、稳定性和找寻地球气候久远记录的研究热点。通过整理总结在Dome A获得的冰川学研究进展，结合国际冰芯科学研究计划(International Partnerships in Ice Core Sciences，简称IPICS)有关寻找最古老冰芯的相关资料，对Dome A的气象要素、地貌、冰厚、冰下地形、冰体流速、冰盖内部结构等环境特征进行归纳分析，讨论Dome A冰川学的最新发展及其对深冰芯钻探计划的影响，并分析概述Dome A深冰芯钻探需考虑的问题和未来发展动向。

Abstract:

Dome A， the highest ice divide in East Antarctic Ice Sheet，is considered a likely place for understanding the evolution and stability of Antarctic Ice Sheet, and finding an ice core with climate record reaching back to one million years. Here, we collect the information derived from studies of glaciology in Dome A, and incorporate the documents for finding the oldest ice core from International Partnerships in Ice Core Sciences (IPICS) . As a result, the meteorology, landform, ice thickness, subglacial topography, ice velocity, internal structure and other environmental information at Dome A, are summarized. In addition, the new glaciological progress and the future development of deep-ice-core drilling plan in the Dome A area also are discussed.

Key words: East Antarctic Ice Sheet, Dome A, glaciology, deep ice core
