The invention provides a control method and device for air-sucking/blowing of a structure around a flow field. The device comprises a vacuum pump, an air pump, an air storage tank, an electromagnetic reversing valve, a vacuum filter, a precise pressure-reducing valve, a vacuum pressure-reducing valve, an air-blowing/sucking airflow main pipeline, a flow meter and a throttle valve, wherein the air storage tank is respectively connected with a ball valve A, a ball valve B and the electromagnetic reversing valve; the electromagnetic reversing valve is respectively connected with the vacuum filter and a common filter; the vacuum filter is connected with the vacuum pressure-reducing valve; and the vacuum pressure-reducing valve is connected with the air-blowing/sucking airflow main pipeline. In the invention, an action effect of an air-blowing/sucking airflow control structure under a natural incoming flow air field is utilized to design and arrange an air-sucking/blowing device in advance, a relation of the air speed of the incoming flow and the flow of the air-sucking/blowing device is designed and preset, and the flow of the air-sucking/blowing device is controlled by comparing the monitored air speed of the incoming flow with the preset air speed of the incoming flow. The device provided by the invention is capable of improving a wind-induced feature of the structure and increasing the wind-induced stability of the structure and is used for wind tunnel test research for various models, such as super high-rise buildings, large span bridges, oceanographic engineering structures, and the like.
