Abstract On the basis of the mobile gravity data in western area of Yunnan province during 1998—2004, the dynamically evolutional characteristics of gravity field in time and space are researched. The results show that 1)the changes of gravity field are closely relative to fault activity；2)the Yongshen Ms6.0, Yaoan Ms6.5 and Dayao Ms6.2,Ms6.1 earthquakes occured in the area were reflected in the sequential phase dynamic change of gravity field.
Key words ：
earthquake test field in Dianxi
mobile gravity surveying
evolution of gravity field
crustal movement
tectonic activity
