【摘要】 利用最新GAM IT软件,对福建省地壳运动观测网络的厦门、福州、泉州、龙岩、南平5个GPS基准站2004年3月1日至2005年3月6日的观测资料在ITRF2000全球坐标系统框架下,使用IGS精密星历数据及其核心观测站的坐标和运动速率为控制参数进行了统一解算,并利用GLOBK软件进行联合平差,得到了5个测站的观测精度。结果表明,福建地区形变南强北弱、东强西弱,且该地区随中国大陆较均匀地向SE(SEE)方向运动。更多还原

【Abstract】 In order to obtain the background materials of earthquake prediction in the Fujian-Taiwan area,we use the controlling parameters of IGS precision ephemeris and its key observation stations’coordinates and movement velocities to uniformly resolve the one-year observation data(March 1,2004 to March 6,2005) of five GPS reference stations of Fujian Crust Movement Observation Network under the global frame of ITRF2000 with the latest GAMIT software,and use the GLOBK software to do an associated adjustment of the observation data,then obtain the stations’observation precisions and movement velocities.The results show that the Fujian area deforms strongly in the south and east but weakly in the north and west,and it moves toward SE(SEE) along with Chinese mainland.更多还原
