摘要
利用最新的GAMIT软件,对1995年到2003年以来海峡5期GPS联测资料,在ITRF2000全球坐标系统框架下,以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统一解算,解算时利用GLOBK软件进行联合平差,得出福建地区地壳运动速度每年小于1mm,并对长乐-诏安断裂带的受力及运动状况进行了分析研究。
Controlling parameters oflGS exaet ephemeris, eoordinates and movement veloeities of the key observation stations are used to unitively resolved the GPS join observation data for five periods from 1995 to 2003 under the global frame of ITRF2000 by using the latest GAMIT software in this paper. The observation data are also assoeiatedly adjusted by using the software of GLOBK to obtain crustal movement velocity in Fujian area. Especially the stress and movement of Changle-Zhaoan fracture zone are analyzed and studied to supply background information for earthquake prediction in Fujian and Taiwan areas.
