| 摘 要： | 利用CSR提供的GRACE时变重力场数据反演2003~2016年南极地区冰盖质量变化。结果表明，南极地区冰盖整体呈现消融趋势，消融速率为（-101.27±7.02） Gt/a，且在不断加速。EA以质量积累为主，速率为（69.09±2.64） Gt/a，但近期速率大幅减小；WA冰盖消融速率为（-148.35±6.78） Gt/a，表现为加速消融趋势，为南极冰盖质量消融的主要地区；AP消融速率为（-22.01±1.44） Gt/a，变化相对平稳。

| Abstract: | We use GRACE time-variable gravity field data, provided by CSR, to invert mass change of the Antarctic ice sheet from 2003 to 2016. The results show that there is a trend of ice sheet melting in the Antarctic region, with the rate of (-101.27±7.02) Gt/a. It is continuously accelerating. Ice sheet mass accumulation appears in the EA region, with the rate of (69.09±2.64) Gt/a, but the rate has decreased greatly recently. The melting rate in the WA region is (-148.35±6.78) Gt/a, which shows an accelerating trend and is the main area of mass melting of the Antarctic ice sheet. The melting rate in AP region is (-22.01±1.44) Gt/a,and the change is relatively stable. |
