The invention provides an active-type rotation roughness element for realizing turbulence quantitative control. The active-type rotation roughness element comprises a support and a top component. The support and the top component are connected vertically through a rotation shaft; the rotation shaft is uniformly provided with three bent fan blades; the top portions of the fan blades are connected with the top component; and a gap is arranged between the fan blades and the support. The use method is characterized in that a wind speed sensor and a turbulence sensor are arranged at a measured point; the rotation speed of a motor is controlled according to the feedback of the turbulence sensor, and thus the required target turbulence is obtained; the measured point is arranged at the lower portion of a building; when the turbulence is too small, a control module sends a speed-up signal to the motor; when the turbulence is too large, the control module sends a speed-reduction signal to the motor; and therefore, turbulence can be measured accurately.
