The invention provides a wing structure with an active flow control mechanism. The wing structure comprises a wing and an active flowing fluid control channel located in the wing, and is characterized in that a plurality of airflow channels with control valves arranged therein are formed between a wing pressure face (the lower wing face) and a wing suction face (the upper wing face) in the wingspan direction to form the active flowing fluid control channel, wherein the control valves are used for controlling the opening and closing of the active flowing fluid control channel; a pressure detection device is arranged on the wing suction face; a flight computer in an airplane is provided with a closed-loop control system which can judge the working opportunities of the control valves according to the pressure detection device; during active control, high-pressure gas on the wing pressure face flows to the wing suction face through the active flowing fluid control channel to conduct synthetic jet on the part, nearby the wing suction face at the tail edge, of a separation area so as to reduce the separation area.
