摘　　要：利用2009年以来的山东流动重力网复测数据,给出了区域重力场差分和累积动态变化图像及GPS站的重力值时间序列分析。结果表明:重力场动态变化图像大体反映出近期山东地壳物质运动状态,累积动态变化更能反映区域构造块体之间的运动与断裂构造作用。The regional gravity field differential and cumulative dynamic change images and the main fault zone near the differences between measuring point and the GPS station time series variation are analyzed by the ob- servation data since 2009 in the Shandong mobile gravity network. The results show that the dynamic variations of gravity field image reflect Shandong crust movement, and the accumulation dynamics also reflect the move- ment of regional tectonic blocks and fracture structure.
