In order to obtain the long-term motions of blocks and contemporary slip rates along major bounding faults in Sichuan-Yunnan region,we built a GPS-constrained linear elastic block model with 24 blocks and eliminated the effect of internal deformation of each block. After the elimination of internal deformation effect,the results show that the RMSE of residual velocities decreased from 1.46 mm/a to 1.15 mm/a. Therefore, one should consider the elastic internal deformation effect when analyzing the motion characteristics of tectonically complicated region using block model.
