摘要
为了研究福建地区活动地块边界带的运动及块体内部变形规律,利用5期GPS观测资料(1995、1997、1999、2001、2003年)计算了福建块体的趋势性差异运动年变速率、优势水平运动年速率,以及在区域无整体旋转基准下各GPS测点运动速率。GPS网5期观测的不同测点速率随时间序列变化结果显示福建活动块体整体向东南方向运动,而块体内部形变量较小(约1mm/a)。
On the basis of the observation data rate of the tendentious differential movement of the for five measurement campaigns form 1995 to 2003, the annual Fujian block, the annual rate of preponderant horizontal movement and the movement rate of each GPS point under the datum of regional non-net rotate are calculated in order to investigate the rule of the border movement between active blocks and of the deformation inside the blocks. The resuits of sequential time variation of the rates at different points for five campaigns show that the Fujian active block, as a whole, is moving southeast, wards and the magnitude of inner deformation is smaller（ about 1mm/a）.
