摘　　要：准确地探明冰盖物质平衡状况,对于研究全球变暖背景下海平面变化具有重要的意义,自IPCC AR4(政府间气候变化专门委员会第四次报告)以来,极地冰盖物质平衡的研究取得了很大进展。本文总结并对比了用卫星测高(雷达测高和激光测高)、物质收支测量和重力测量等方法得到的冰盖物质平衡评估结果,综述了冰盖数值模拟研究在预测冰盖未来的变化趋势以及由此对海平面造成的影响等方面取得的进展,并立足于中国当前的极地冰盖物质平衡研究现状,提出了该研究所面临的挑战。To investigate sea-level rise caused by global warming, it is important to accurately assess polar ice sheets mass balance. Since the Intergovernmental Panel on Climate Change Fourth Assessment Report, new observations of ice-sheet mass balance have been published, with improved computer simulations of the response of ice sheets to ongoing climate change. This paper discusses progress in research into ice-sheet mass balance using satellite altimetry, mass budget, and sateUite gravimetry techniques, with special focus on new estimates of ice-sheet mass balance and improved ice-sheet modeling, as well as predicted future ice-sheet changes. Future challenges in the study of ice-sheet mass balance are also discussed.
