Abstract In the light of the 5 periods of mobile gravity observation results of the JiLuYu network, the relation between the gravity and the Fengqiu earthquake is discussed. It is found that before and after Fengqiu earthquake the gravity station value in the juncture area of Hebei，Shandong and Henan under went three stages:first,it went down,then rose and finally,went down again.It reflected the three stages of the Fengqiu earthquake process as seismogenic stageoccurancepostearthquake adjustment.It is proved that the gravity variation in JiLuYu observation region was the anomaly before Fengqiu earthquake.
