采用多层相位屏法模拟了艾里涡旋光束在大气湍流中的漂移特性。讨论了拓扑电荷p、涡旋核相对于光束中心的离轴距离x_d，y_d 和湍流强度C²_n 对艾里涡旋光束在不同传输距离处的漂移特性的影响。研究发现，在相同传输距离处，漂移量随着C²_n 的增大而增大。在传输距离比较小时，p 和x_d，y_d对漂移的影响比较弱，漂移量几乎相等。当传输距离比较大时，漂移量随p 的增大而减小，随x_d，y_d的增大而增大。此外比较了单束艾里涡旋光束的漂移量和阵列艾里涡旋光束的漂移量，研究发现，阵列艾里涡旋光束的漂移量比较小。

The drift characteristics of Airy vortex beam in atmospheric turbulence are simulated based on multiple phase screens method. The drift characteristics influenced by topological charge p, the off-axis dislocations x_d, y_d of the vortices core from the optical center and the intensity of turbulence C²_n are investigated in different distances. It is shown that the drifts increase with the increase of C²_n in the same distance. When the distances are short, the drifts are nearly equal because of the weak influence of p and x_d, y_d. When the distances are long enough, the drifts decrease with the increase of p, but increase with the increase of x_d, y_d. In addition, by comparing the drifts of single Airy vortex beam with the Airy vortex array beams, it is shown that the drifts of Airy vortex array beams are smaller.
