中文摘要：

在中国境内所有的二级块体运动中,川滇区域的地壳运动最为活跃,也是各学者研究的热点领域。本文通过对1998—2008年和2008—2015年两期GNSS连续观测数据的解算（时间节点为汶川地震）,并结合前人对川滇区域棱形块体的划分方案,利用欧拉矢量计算出各次级块体的欧拉矢量。对该区域进行了网格插值从而反演两期地壳运动变化特征,以及通过在断裂带上或断裂带附近选取一点来研究相邻块体的相对运动趋势变化,并对该区域内地块垂向运动作了初步研究分析。结果表明,汶川地震并没有造成该区域整体运动特征的改变,但对一些局部块体的运动和相邻块体的相对运动带来了一定的影响。

英文摘要：

The crustal movement in the Sichuan Yunnan region is the most active around China,which is also the hot spot of the scholars＇ research. Based on the GNSS continuous observation data solution（ time node for the Wenchuan earthquake） in 1998—2008 and 2008—2015,combined with the previous classification scheme of the Sichuan Yunnan region prismatic block,Euler vector of each block is calculated based on the Euler vector. In this region,grid interpolation is used to retrieve the characteristics of two periods of crustal movement,and to study the relative motion of adjacent blocks by selecting a point in the vicinity of the fault zone or the fault zone. The results showed that the Wenchuan earthquake did not cause the change of the whole movement characteristics,but the movement of some local blocks and the relative motion of the adjacent blocks.
