Based on the combination of the synthetic rate,the trend accumulation rate method and the cross-fault data,this paper analyzes the movement characteristics of the main fault strain accumulation in the northeastern margin of the Qinghai-Tibetan Block from different angles of time and space. The result shows that:(1)In the short term,the movement situation of the Qilianshan fault zone is weak. The movement characteristics of the Haiyuan fault is from extension to extrusion. Before the Menyuan earthquake,the movement characteristics of the Liupanshan fault is extension,and has a turning point.(2)In the long run,the calculation results based on trend accumulation rate show that the cumulative strain of the middle west of Qilianshan Fault zone is slightly higher than the East. From the numerical value about the northeast margin of Qinghai-Tibetan Block,the D_c high value region is near the Liupanshan faults.
