Abstract：The paper processes a total of 18 mobile gravity retest data of Hainan Island from 2003 to 2014, and analyzes the cumulative changes of gravity field and the timing variations of gravity point value of measuring points in key areas from the perspective of time and space changes of gravity field, to recognize the gravity field evolution of Hainan Island. The paper focuses on the timing variations of gravity point value of measuring points before and after the ML 4.1 earthquake on July 9th, 2004, ML 4.3 double earthquakes on July 30th, 2004 in Lingshui offshore and ML 4.1 earthquake on November 5th, 2012 in Wanning offshore, and the results show that there is no abnormal changes of the gravity field of Hainan Island before and after the above earthquakes.
