The invention relates to an aircraft partition deicing method and system. The method comprises the following steps: emitting detection ultrasonic waves to a skin of a target deicing area of an aircraft, and obtaining echo signals of the detection ultrasonic waves; the real-time reflection coefficient of the target deicing area is calculated according to the amplitude of the detection ultrasonic waves and the amplitude of the echo signals, and whether an ice layer exists in the target deicing area or not is judged according to the real-time reflection coefficient; and under the condition that the ice layer exists in the target deicing area, the icing severity degree of the target deicing area is judged according to the thickness of the ice layer and the flight duration of the airplane, and the heating power of the electric heating deicing assembly in the target deicing area is controlled according to the icing severity degree. According to the airplane partitioned deicing method and system provided by the invention, targeted partitioned deicing operation can be carried out according to the actual icing condition, the energy consumption of airplane icing protection is reduced, and the flight safety is improved.
