摘要
应用最新的全国垂直形变速率图和各地区不同年代的形变（速率）图，编绘了相应的形变速率梯度图，计算了若干跨断层测量台、点资料的低通滤波残差及其一阶和二阶差分。结合在相应空间和时间域内所发生的强震，讨论了地壳形变与强震的关系，探讨了用大地形变测量方法划定近期（１—３年或稍长一点时间）强震危险区的判据，得到了一些有意义的结果。
Based on the latest map of vertical crustal deformation rate of China and maps of crustal deformation rate in different years and various regions, the corresponding maps of crustal deformation rate gradient are drawn and the low-pass filtered residual and its first and second order differences of the data from several cross fault stations and points are calculated. Combined with the strong earthquakes occurred in the relevant space and time, foe relationship between the crustal deformation and the strong earthquake is discussed and the criteria for dividing near-future (1 to 3 years or more) strong earthquake risk regions by crustal deformation monitoring method are approached and significant results are obtained.
