英文摘要：

Merging Point approach is a new approach technology. 4D trajectory planning method for arrivals in merging point approach is studied in this paper. According to the characteristics of merging point approach , a trajectory prediction method is present. A4D trajectory planning model is built based on two objectitotal delay and minimum sequence adjustment,and genetic algorithm is employed to solve the problem. The difference between the planning result of the method and that of first come first serve method is present. The simulation shows that 4D trajectory planning method can improve the operation efficiency in terminal.
