The invention discloses a method for preparing an anti-microbial, mildew-resistant and corrosion-resistant membrane layer on a magnesium metal surface. Firstly a magnesium metal is pretreated, and then is put in an oxidation fluid. An alternating current with a current density of 0.5-2.5 A / dm<2> is connected. A layer of oxidation functional membrane is formed after the treatment is carried out for 10-40 minutes at the temperature of 15-30 DEG C. Then the magnesium metal is rinsed by deionized water and is sealed t in the pure water. The oxidation membrane layer with the thickness of 3-15[mu]m is obtained on the magnesium metal surface. The oxidation fluid contains the following solute: 40-80g / L NaOH, 50-90g / L Na2SiO3, 40-80g / L Na2B4O7, and 8-16g / L citric acid, and also contains soluble anti-microbial and mildew-resistant functional element salts. The magnesium metal surface after treatment by the method of the invention has a layer of the oxide membrane which takes a magnesia ceramic phase as a matrix. The anti-microbial and mildew-resistant functional elements Ag and Ni are dispersed and distributed in a matrix phase. The membrane layer has the good anti-microbial and mildew-resistant performance and good corrosion resistance, and can be used in many fields such as package and storage of food and clothing, and human body implantation medical instruments.
