Abstract Using the rate data of vertical deformation field from 1970 to 2014 at the surroundings of Ordos block, with the help of negative dislocation inversion, we study the long-term strain accumulation. The results show that, the first average annual growth rate of energy accumulation and shear stress is the middle-northern segment of Shanxi fault belt at the northeastern margin of Ordos block, the second is the Liupanshan fracture and the western segment of Weihe fracture at the southwestern margin of Ordos block. The segments with high shear stress and relatively lower energy accumulation are the middle-southern segment of Shanxi fault belt and the border between Shanxi and Shaanxi. The western Qinling mountains tectonic area, especially the western segment of the northern margin fault of the west Qinling mountains, and the border area between Shanxi, Hebei and Inner Mongolia, also reflect the characteristics of energy accumulation.
