摘要

摘要: 华北地区的形变信息较弱,GPS获得的地壳长趋势的构造变化信息是否可以反映华北地区的形变信息尚未有人讨论。本文利用多面函数双调和法对华北地区COMNOC的GPS速度场进行建模、滤波,计算了华北地区的应变率,进一步通过误差传播率评估了应变率的精度。综合分析表明,多面函数双调和法计算得到的应变率具有很高的精度,精度结果分布与实测数据相符,实测点越多的区域,应变率的精度越高。

Abstract: Deformation of North China Region is very small, there is little discussion about whether GPS long-term crustal tectonic deformation can reflect the deformation of North China Region or not. In this paper the GPS velocity field of COMNOC-I was used to calculate the strain rate and its accuracy for North China using multiquadric-biharmonic method. Analysis of standard deviation, calculated by the law of error propagation, shows that these strain rate results are highly accuracy. And that the reliable results distribution was consistent with the measured data. The more measured point the higher the accuracy of the strain rate.
