The invention relates to the technical field of airplane wheel brake control, in particular to a deceleration rate-slip rate type anti-skid brake control method which comprises the following steps: acquiring the real-time deceleration rate of an airplane in the current period; acquiring an anti-skid front brake instruction value of the current period; acquiring the anti-skid amount and the state of the airplane wheel in the current period; acquiring an anti-skid instruction value; and brake pressure is obtained, and brake is conducted. According to the method, the airplane is controlled to brake at the specified speed reduction rate, and meanwhile, the airplane wheel reference slip rate is dynamically adjusted in real time, so that the airplane can utilize the ground bonding torque to the greatest extent on different runways, namely, the optimal slip rate of the current runway is found; the slip rate of the airplane wheel relative to the airplane is in the optimal slip rate range, the combined torque is utilized to the maximum extent, the anti-slip braking efficiency is improved, and the braking distance is shortened.
