The invention relates to a low-altitude mobile wind speed measurement method based on a four-rotor unmanned aerial vehicle, and belongs to the field of wind speed measurement. After taking off, the four-rotor unmanned aerial vehicle flies or hovers in the air, the unmanned aerial vehicle transmits flight parameters to a ground receiving system through airborne equipment in a wireless transmission mode, the ground receiving system calculates the flight parameters through a program, and the position (height, longitude and latitude) of the unmanned aerial vehicle is obtained; the wind speed and the wind direction of the position are obtained according to the pre-determined corresponding relation between the flight parameters and the wind speed in combination with the flight parameters (the rotor rotating speed, the unmanned aerial vehicle inclination angle, the unmanned aerial vehicle acceleration, the unmanned aerial vehicle speed, the unmanned aerial vehicle mass and the like). The method has the advantages th
