基于陆态网络GPS连续站揭示中国大陆现今垂直形变特征
Journal: Geological and Mineral Surveying and Mapping DOI: 10.12238/gmsm.v3i5.872
Abstract
中国大陆内部构造变形复杂,是全球板内构造和大陆动力学研究的热点地区之一,而垂直形变特征对理解该地区的动力学过程具有重要的参考价值。本文通过对收集整理的260个2010~2020年陆态网络连续GPS观测资料进行统一的高精度处理,获取了该地区的垂向形变速度场,并对速度场精度进行了统计分析。结果显示大部分站点的垂向速率精度达1mm/yr,垂向形变速度场揭示了中国大陆垂向形变与地形的继承性及区域差异性特征。
