基于GPS观测的地壳垂向季节性运动研究进展
|
摘要
介绍了基于GPS观测获取的地壳垂向季节性运动组成及相应的分析方法,阐述了地壳季节性运动在GPS流动垂向季节性修正、区域负荷质量变化监测、应力扰动与地震活动性的季节性变化分析、区域地壳结构反演等方面的应用研究进展,认为利用GPS观测研究地壳季节性运动的应用正向多手段、多学科融合发展,但需进一步完善数据处理模型(策略)、削弱解算结果中的误差,且各区域的地壳季节性运动机理值得深入分析。
In this paper,the composition and the corresponding analysis methods of seasonal vertical crustal motions obtained by continuous GPS observations are introduced.Then,we discuss on the application of seasonal crustal motions on the verification of vertical motions in campaign GPS observations,monitoring the variation of mass loading,analysis of stress perturbation and seasonal variation of seismic activity,and inversion of crustal structure,etc.At last,we proposed that the application of GPS in the study of seasonal crustal movement is developing towards the integration of multi-means and multi-disciplines. In the future,it is necessary to further improve the data processing model(strategy) and weaken the errors in the results. At the same time,the mechanism of seasonal crustal movement in different regions deserves more in-depth analysis.
