摘要：
In this paper, the probability of the collision behaviors of barchans in aeolian dune fields and the processes of three collision types, i.e., coalescence, breeding and solitary-wave like behavior, are analyzed by the scale-coupled model of dune fields. Moreover, the influence of wind speed, sand diameter, sand supply, the height ratio between two barchans, and the angle between the dune trend and wind direction, as well as the distance between the centerlines of two barchans on the collision results of barchans is demonstrated.
