提出一种检验地应变(率)显著性的统计方法,并利用该方法分析了华北地区通过GPS观测位移场计算得到的显著应变的空间分布,结果表明,显著应变主要分布在华北地区现今活动块体边界带上,而那些地应变不显著的站点集合形成了块体的内部区域.

A statistical method for testing the significance of strain components calculated from geodetic data is proposed. By analyzing the spatial distribution of significant strain, the characteristics of tectonic strain can be properly displayed. The proposed method has been used for determining the spatial strain distribution in North China from GPS data. The results show that the significant strains distribute mainly in the boundary of tectonic blocks. On the other hand, distributions of un-significant strains form the interiors of tectonic blocks, it is helpful for division of active tectonic blocks.
