| 摘 要： | 全球海平面变化关系着人类的生存和发展,一直以来就是科学界重点关注的问题;而南极地区存储的冰是影响海平面变化最主要的因素。主要详细地阐述了冰后回弹的基本理论,以及利用GRACE重力数据计算冰后回弹的基本理论;并推导了相关的计算公式。最后,利用GRACE月重力场数据对冰后回弹和南极地区质量变化进行了试算。实验结果表明:南极地区冰后回弹效应范围为-0.987~20.3 mm/a;其中在极点附近的冰后回弹效应较强。

| Abstract: | it is very important for the human survival and development that is the change of global sea level. This problem has always been paid close attention by scientists. And the stored ice in the Antarctic is the most important factors that affect the sea level change. The basic theory of ice rebound is elaborated, other method about the ice rebound calculated by GRACE gravity data and the related calculation formula was deduced this article. Finally, there is the data calculation about ice rebound and the change of Antarctic ice caps by GRACE gravity field data. The results showed that the ice rebound effect range of Antarctic is -0.987 ~20.3 mm/yr, and the effect of ice rebound is stronger near its poles. |
