The invention belongs to the field of restoration of environmental heavy metal pollution, and particularly discloses a method for restoring copper-polluted water by utilizing salicylic acid to strengthen scindapsus aureus, which comprises the following operation steps: 1) planting the scindapsus aureus in the copper-polluted water, and applying 50-200mu M salicylic acid for growth culture; and 2) removing the grown and cultured scindapsus aureus from the polluted water body, and by means of repeated planting and repeated operation, achieving the purpose of accumulating excessive copper in the water body into the scindapsus aureus, and finally enabling the copper content in the polluted water body to meet the national water quality standard requirement. The salicylic acid is applied to strengthen the scindapsus aureus to repair copper pollution, growth of the scindapsus aureus can be promoted, the capacity of the scindapsus aureus for accumulating heavy metal copper is improved, the water quality is improved,
