Abstract:: The mobile gravity data in Lantianwu area during 2000～2006 is systemically analyzed,and dynamically evolutional characteristics in time and spatial domains of gravity field is researched.From the research results we have had following understandings.The change of gravity field is closely relative to tectonic of active fracture; The change of gravity may be relative to micro-dynamic situation of stress-strain field; The Minxian M_S5.2,M_S5.0 and Wudu M_S5.0 earthquakes are closely relative to the followed two dynamic patterns of gravity field.
