The invention provides a heat flow spatial domain loading and evaluation method in the ignition flight process of an attitude control engine, which is mainly used for solving the problems that in the prior art, the non-uniformity of heat flow loading at the flight moment of the attitude control engine cannot be accurately measured, and radiation heat environment characteristics generated by a quartz lamp heater cannot be truly and accurately obtained. And errors are introduced in the performance verification process. According to the method, heat flow loading of different dimension space domains is carried out on a to-be-measured attitude control engine mainly through loading modes of different degrees of freedom, and a multi-dimension distribution state diagram and a multi-dimension loading spectrum are obtained; meanwhile, in combination with different loading capacities of the quartz lamp array, spatial domain multi-scale heat flow loading of the attitude control engine to be measured is realized in differ
