The invention discloses a spacecraft orbit threat autonomous avoidance task planning method based on a PDDL, and the method comprises the steps: building the field description of spacecraft orbit threat autonomous avoidance task planning through employing a PDDL based on the evolution and dependence relation of behavior actions of each parallel subsystem of a spacecraft along with time; based on the threat perception process of the spacecraft and the environmental condition of the spacecraft, a PDDL language is adopted to construct a problem description of spacecraft orbit threat autonomous avoidance task planning; generating a spacecraft orbit threat autonomous avoidance task planning problem in combination with the field description and the problem description; the task planning problem is solved, a planning solution is output, and the planning solution is a state sequence set and represents evolution of each subsystem from an initial state to a target state in a given planning interval; according to the method, a series of execution sequences for avoiding tasks are autonomously generated, so that coordinated operation for dealing with orbit threats when the spacecraft executes established tasks is realized.
