作为中低纬度最大的冰川作用区,高亚洲冰川在全球普遍变暖背景下加速退缩,冰川物质平衡发生明显变化,直接影响了全球海平面变化、区域水资源利用及生态环境.本文在介绍TanDEM-X双站SAR科学计划的基础上,提出了一种基于双站InSAR的冰川质量变化探测新方法.并以青藏高原普若岗日冰原为例,利用双站InSAR提取的TanDEM-X DEM和SRTM-X DEM,成功获取了该冰原2000-2012期间高精度、高分辨率冰川厚度和质量平衡的变化信息,初步验证了该方法在高亚洲冰川质量变化定量探测方面的巨大应用潜力.研究结果表明,该冰原积累区冰川质量略有增加,而消融区明显减少;与青藏高原中部其他冰川比较,其总体质量变化更为稳定.

不同积分方法对计算地球转动惯量的影响

传统形状理论在研究地球内部结构与形状时一般采用流体静平衡态假设并结合一维地球模型进行计算,其所得的地球内部等势面形状具有对称性,但已知的地球内部物质分布极其复杂,是不能简单地作为一个对称体讨论的.本文根据前人所提出的一般形状理论,全面考虑了地壳地形存在及其影响,所求得的等势面形状更为真实地反映了地球内部物质分布状况,并将地球从壳幔边界处分成内外两部分求解了各自的地球转动惯量.研究表明地壳质量虽然不
