摘　　要：使用福建GPS台网2004年3月到2006年9月的连续观测资料，经数据处理获得时间序列分析结果。初步估算了各测站的运动速率和定位精度，水平向在1．5～3．2mm，垂直向在6．6～8．2mm。选取区域相对水平位移变化量较小的5个台站组成的一组稳定点作为基准，讨论了各测点的相对运动速率及时空变化特征。从水平位移结果分析表明，现今福建地壳运动的趋势仍十分缓慢且整体较为平稳，与华南地块同中国大陆其他地区比较呈相对稳定相吻合。Continuous observation data from March 2004 to Septermber 2006 of GPS network in Fujian province are analyzed primitively by using Kalman filtering. After processing data, movement velocities at stations are estimated. Based on choosing five stations at which horizontal displacement are small as basic stations, the synthetic analysis of continuous observation results, displacement at stations have been obtained. Continual time observation series and movement velocities character at stations are discussed. Results of analysis indicate that horizontal displacement of crust in Fujian is very small and the movement direction is southeast as same with direction of China continent movement
