冰川均衡调整(GIA)的研究

A review of research in glacial isostatic adjustment

冰川均衡调整对固体地球物理学、大地测量学、地貌学、海洋学、冰川学、气候变化、水资源、天文学和考古学等学科具有重要的意义,通过其综述性介绍,以吸引我国地学界的注意和兴趣.本文结合作者和国内外研究成果,全方位地阐述了冰川均衡调整研究的完整内涵,首先给出了冰川均衡调整的完整概念,探讨了冰川均衡调整对冰后地壳运动、全球海平面变化、地球重力场、地球旋转运动和应力状态的影响,再分析了冰川均衡调整研究的科学目标和冰川均衡调整研究的历史与现状,最后指出了冰川均衡调整研究的未来发展方向.

Glacial isostatic adjustment of the Earth disciplines of science including solid geophysics, is a young field which has important implications in different geodesy, geomorphology, oceanography, glaciology, climate change, water resources, astronomy and archaeology. It is hoped that this review will attract the attention and interest of geoscientists in China and that they may contribute to this important field. This paper presents results of current and past scientific studies on this subject around the world including those of the authors. First of all, the concept of Glacial isostatic adjustment is introduced including its effects on crustal motion, global sea levels, changes in Earth＇s gravity field, rotational motion and the state of stress. Secondly, the scientific objectives, research history and present status are also examined. Finally the paper ends with a discussion on the future developmental trend of Glacial isostatic adjustment.
