摘　　要：系统分析了胶东测区1996—2009年期间流动重力测量资料，着重探讨了1996年以来相邻期的重力点值的空间变化规律，重力场有规律的变化表现为：胶东测区自观测以来有着活跃-平静-活跃-逐渐稳定的变化过程。另外，分析了胶东测区内断裂带附近的部分测点的点值和段差值变化特征，认为重力场变化与活动断裂构造密切相关，从而进一步加深了对胶东测区重力场时、空、强动态演化特征的初步认识，这为今后对山东地区重力场深入分析和研究打下了坚实的基础。The gravity measurement data during the period from 1996 to 2009 in Jiaodong area is analyzed, especially discussed the characteristics of the space variation of gravity field since 1996, and the characteristics present the process of active--a long - term quiet --active--stability. It is also analyzed variation characteristics of point - value and period - value in the faults in the area, and the results show that the gravity field variations are closely related with the active faults. And this research is the basis for the further study of the regional gravity field in Shandong province.
