The invention discloses a communication resource and computing resource joint allocation method in unmanned aerial vehicle auxiliary emergency communication. The method comprises the following steps: constructing an unmanned aerial vehicle auxiliary emergency network platform; acquiring state information based on an unmanned aerial vehicle auxiliary emergency network platform, and constructing first, second and third queuing models according to the state information; calculating a first queuing time delay according to the first queuing model, calculating a second queuing time delay according to the second queuing model, and calculating a third queuing time delay according to the third queuing model; constructing a weighted sum function model according to the first queuing time delay, the second queuing time delay and the third queuing time delay; decoupling the weighted sum function model into an air base station and ground user association strategy sub-problem, an air base station and ground base station task unloading strategy sub-problem and an air base station trajectory planning strategy sub-problem by using a Lyapunov stochastic optimization method; and solving each sub-problem to obtain a corresponding air base station and ground user association strategy, a track planning strategy and a task unloading strategy. According to the invention, the communication task calculation time is reduced.
