Abstract Using GPS observation data of the 1999, 2001, 2004 and 2007 phases of the China crustal movement observation network, interpolation is applied to gain the boundary conditions of a 2-D element discontinuous model, which is used to simulate the slip rates of the fault system in Longxi area and undertake uncertainty analysis over it. The study determines that the NNE direction movement of Longxi block had been hindered by Orods and Alxa blocks. Haiyuan fault, Laohushan fault, and northern Xiqinling fault show a left-hand strike slip characteristic, and the slip rates are about 3.5 mm/a, 2.2 mm/a and 1.9 mm/a respectively, which means that the tectonic stress has been accumulating in the key tectonic section rapidly.
