The invention provides an alloyed galvanized sheet and a preparation method and application thereof. The alloyed galvanized sheet comprises a base plate and an alloyed coating attached to the surface of the base plate, and the alloyed coating is composed of following chemical components of, in percentage by mass, 0.10%-0.14% of Al, 0.5%-1.2% of Mg, 7%-12% of Fe and the balance Zn and inevitable impurities. The stripping proportion of the alloyed galvanized sheet is 2.3%-2.8%, the adhesivity is good, the red rust occurrence time is 810h-1020 h, the corrosion resistance is good, spot welding splashing does not occur in the welding process, and the welding performance is good.
