In order to further analyze and predict the changing trends of the Fu Jian Ping Tan(FJPT) station's variable velocity field, and then grasp its motion variation characteristics, the stationary test is carried out based on the time series of the eastward speed and the northward speed of the FJPT station from 2010 to 2018. According to the test results, it is an unsteady random non-monotonic time series. Therefore, the gray system Verhulst model is employed to predict the eastward and northward annual average momentum of the next 10 years. The prediction results show that the speed of the FJPT station is gradually deflected from the west to the east and from the north to the south, and the station speed is deflected from the northwest to the southward. The south side of the southeast coastal block is in the southeast movement, and the FJPT station turns around the southeast coastal block in clockwise.
