The invention belongs to the field of ablative material heat flow control tests, relates to a general control or regulation system, and particularly relates to a heat flow control test method. The method comprises the following steps: 1, acquiring temperature data of an ablative material test piece in a historical heat flow control test; 2, selecting a heat flow meter arrangement point according to the temperature data; 3, acquiring a standby command value of a heat flow control test; and 4, performing a heat flow control test. According to the heat flow control test method, the heat flow load loading area is divided into a plurality of temperature areas, and the heat flow meter arrangement points are reasonably selected, so that the heat flow control precision can be improved; and the feedback value of the heat flow meter is judged in real time, and when the heat flow meter breaks down, a closed-loop feedback control mode is switched into an open-loop power control mode in time, so that risks caused by failure of the heat flow meter are avoided, it can be guaranteed that an ablative material test is smoothly completed in a ground heat intensity simulation test, the reliability of the test is improved to a great extent, and the application value is very high.
