The invention discloses a method for enhancing the performance of a magnesium-based composite material, and aims to improve the comprehensive mechanical property of the magnesium-based composite material. The method comprises the following steps of: placing as-cast magnesium ingot in a cast-iron crucible which is pre-heated to 400 DEG C so as to pre-heat the as-cast magnesium ingot; scattering a covering agent special for a magnesium alloy on the surface of the as-cast magnesium ingot so as to prevent oxidation; after the magnesium ingot is completely melted when the temperature is raised to 710 DEG C, preserving the heat for about 5 minutes and removing the surface impurity; then placing the reinforced phase nickel-plated CNT and SiCp into the crucible and stirring the materials for 5 minutes; standing the materials for 1 minute after stirring; and when the furnace temperature is raised to 710 DEG C, removing the surface impurity, casting, solidifying and then stripping the mould.
