The present disclosure provides a high-efficient rolling process for magnesium alloy sheet. Parameters of the rolling process are: the rolling speed of each rolling pass is 10-50 m/min, the rolling reduction of each rolling pass is controlled to be 40-90%, and both the preheating temperature before rolling and the rolling temperature of each rolling pass are 250-450&#xb0; C. The present disclosure also provides a preparation method for magnesium alloy sheet, comprising: 1) preparing rolling billets; 2) high-efficient hot rolling; and 3) performing annealing. The rolling process can improve the mechanical performance especially, the strength and ductility of the sheet.
