摘要
以天山构造带区域为例,分别用精密水准和GNSS给出地壳形变垂直运动速率矢量图,对其差异及差异形成的原因进行深入分析和探讨,并基于优势互补原则,给出二者融合的形变图像。根据多年研究经验认为,该方法得到的垂直形变图在强震中长期预测中具有较为重要的应用价值。
Taking the Tianshan tectonic belt area as an example,we give the crustal deformation vertical movement rate vector maps,using precision leveling and GNSS,respectively.We analyze and discuss in depth the differences and their causes.Based on the principle of complementary advantages,we give the deformation image of the fusion of the two.Based on many years’research experience using geodetic deformation data to predict strong earthquakes,we consider that the vertical deformation map obtained by this method has more important application value in the study of strong earthquake prediction.
