A medical dressing hydrogel composite fabric, and a preparation method therefor and uses thereof. The preparation method comprises: dissolving N-isopropylacrylamide and an initiator by using a solvent, and foaming by using nitrogen performing an initiation reaction on cotton cellulose in the initiator soaking the cotton cellulose after the initiation reaction in the mixed solution of N-isopropylacrylamide and dimethylfomamide, and then performing a polymerization reaction in the presence of nitrogen to obtain poly N-isopropyl acrylamide-cotton cellulose dissolving poly N-isopropyl acrylamide-cotton cellulose together with alginate into distilled water to form hydrogel on the surface and removing the solvent to obtain the medical dressing hydrogel composite fabric.
