| 摘 要： | 利用GPS观测资料研究地球动力学问题是目前地学中的热点。利用GPS观测的速率(或位移)计算网格点附近小区域的应变张量和转动的欧拉极．再运用聚类分析法对计算的欧拉极进行分类，由此划分出地壳活动的次级块体。最后以中国大陆GPS观测结果为例，将中国大陆划分为9个活动块体，通过比较发现，所得结果与目前其他方法给出的结果大体一致。

| Abstract: | Studying geodynamics by GPS measurement is a hotspots in earth science. In this paper, we calculate the strain tensor and Euler pole by velocity or displacements measured by GPS in the small area about grid points, and classify the calculated Euler pole by cluster analysis method,and thus the present crustal sub blocks are divided. Finally,China continent is divided into nine active blocks on the basis of the results of GPS measurement.We have found out that the sub blocks determined in this paper are consistent with that obtained by other method in general. |
