The invention discloses a hierarchical clustering network topology structure generation method based on multi-task unmanned aerial vehicle cluster information interaction. The method comprises the following steps: a step of determining an unmanned aerial vehicle cluster set and a position matrix of each cluster; a step of constructing a network topology structure of intra-cluster information interaction of each cluster; and a step of constructing a network topology structure of inter-cluster information interaction. According to the method, the unmanned aerial vehicle cluster is self-organizedby using the hierarchical clustering structure, and the mode of executing different tasks in different clusters is adopted, so that the problems that the scale of the unmanned aerial vehicle clusteris limited and information interaction only faces a single task are solved. Centralized control is adopted in a cluster in SCH topology of multi-task unmanned aerial vehicle cluster information interaction, a minimum spanning tree is calculated with a cluster head as a root to construct a network topology structure of any independent cluster, and therefore information interaction in all the independent clusters is completed. A spatial interaction gravitation model is introduced between the clusters to construct an inter-cluster network topology structure so as to complete information interaction between the unmanned aerial vehicle clusters.
