The invention discloses a method for accelerating pollutant diffusion through air flow change caused by building layout. The method is characterized in that, with a crossroad being a center original point, the two sides of each of roads in east-west and south-north directions are respectively provided with buildings; the buildings are arranged at the two sides of the road in the east-west direction in such manner: the buildings are arranged at the two sides of the road symmetrically with the center line of the road in the east-west direction being a symmetry axis, the buildings are arranged from low to high in height according to the distance, from far to near, between the buildings and the center original point of the crossroad, each building and the center line of the road form a certainangle, and a pair of buildings arranged oppositely form a horn mouth, the included angle of which is alpha, wherein the small mouth of the horn mouth faces the crossroad, and the included angle alphais calculated through a f
