Gravity change is an important content of earthquake monitoring and prediction.This paper collected and sorted out 8 phase mobile gravity observation data in southern Liaoning Province during 2012-2015.We studied regional space-time variation of gravity field,gravity values of temporal variation and difference of temporal variation etc;analysised of gravity field,spatial and intensity variations by gravity adjustment calculation.Finally determined the high risk area of potential earthquake.Results show:the change of gravity in Dashiqiao Haicheng Gaizhou area and the Ming Yang Zhuanghe Wei Tun area is larger,and the anomaly is obvious,Should pay close attention to these region.
