近日，中国极地研究中心冰雪所"极地冰盖多圈层相互作用与气候变化"研究团队联合西安建筑科技 大学交叉创新研究院、吉林大学地球探测科学与技术学院等单位将南极冰盖伊丽莎白公主地冰下地貌形 态特征量化。该研究首次通过机载冰雷达数据揭示了伊丽莎白公主地区域基底粗糙度的空间分布特征， 阐明了其与冰流速度及方向的复杂关联关系，并对其冰下环境的区域特征进行了推断解析。研究为剖析 伊丽莎白公主地冰下条件和底部环境提供了关键依据，将有助于提升并优化南极冰盖数值模式的冰底参 数化方案和底部边界条件。 南极冰盖储存了全球约70%的淡水，其稳定性直接影响全球气候与海平面变化。然而，冰盖底部条 件的复杂性长期制约着冰流动力学模型的模拟精度。冰下地貌通过影响冰底地质边界条件的关键过程 （如水热反馈、基底滑动等）对南极冰盖的物质动态损失起着控制作用。量化冰下地貌形态特征的一个 重要几何指标是基底粗糙度，其刻画了基岩与基底沉积物表面或结构面的不平整程度（即其起伏变化特 征）。基底粗糙度及其影响因素（如冰流速、地热通量等）相联系，可用于理解冰下基底条件并推断冰 盖的冰动力学状态。 东南极伊丽莎白公主地面积约90万平方公里，占整个东南极冰盖的1/ ...
