The invention belongs to the field of bioengineering and specifically relates to a recombinant human-like collagen gel dressing for wounds, a preparation method and a use method thereof. The recombinant human-like collagen gel dressing comprises a regenerating agent and a cross-linking agent; the regenerating agent and the cross-linking agent are suitable for taking part in a cross-linking reaction so as to form a hydrogel state on wound surface; a special spraying device is used for spraying on wounds simultaneously and preventing a part of wounds from being uncovered or exposed and the recombinant human-like collagen gel dressing from being unevenly coated; hydrogel is similar to extracellular matrix in matrix, has excellent water-absorbing and water-retaining properties and high air permeability and is capable of supplying a humid repairing environment to wounds.
