Zusammenfassung:The invention discloses a method and device for inputting fresh air into cities through subway tunnels to input a large amount of the fresh and clean air into the cities through the subway tunnels byadopting the period of time when subways stop working at night so that city residents can also breathe the fresh and clean air. Meanwhile ventilating is reinforced, and thus haze is also eliminated. According to the method and device for inputting the fresh air into the cities through the subway tunnels, the subway tunnels are adopted, the effect that dual purposes are achieved through one objectis achieved, and investment and manpower and material resources are greatly saved. The aim of the method and the device is achieved through the following technical schemes that an air conveying facility comprises a draught fan array which is connected with an air collection station, and the air collection station is connected with a ground air conveying pipeline; and the ground air conveying pipeline is connected with the
