| 摘 要： | In the process of solving Euler vectors based on GNSS horizontal movement field, the number of estimated parameters can affect Euler vector results. This issue is analyzed through theoretical deduction and practical example in this paper. Firstly, the difference between the results of Euler vectors in different solving models is deduced. Meanwhile, based on GNSS horizontal movement field in the Chinese mainland from 2004 to 2007, two common models （ RRM and REHSM） are used to discuss the impact of solving models on Euler vectors and the follow-up study. The result shows that the maximum value of the difference in a block＇s entire rotation can reach 2. 6mm/a, and should not be ignored. Therefore, the results of horizontal movement are different using different kinematic block models, and this should be paid more attention in the analysis of crustal horizontal movement.
