Abstract Using precise leveling data of the north of Yilan-Yitong fault zone in 1977, 1991 and 2015, we take the pseudo inverse linear dynamic movement model in the case of reference to carry on the adjustment, and reduce to the selected benchmark. We then obtain the two relative velocity fields in the region (1977-1991 and 1991-2015). The previous velocity field shows that roughly Yilang-Yitong fault zone is bounded, the north of Changbai mountain is a relatively uplifting movement compared to the southern section of Lesser Khingan Mountains, with a maximum relative rate of 7.51 mm/a. The second phase of the rate field indicates a relatively low speed of the northern region of the Yilan-Yitong fault zone, with a maximum relative rate of only 3.4 mm/a. The area tends towards a holistic approach to inheritance; the relative motion of the fault line decreases significantly.
