The invention relates to anti-postoperation scar degradable multi-branched glycopeptide hydrogel and a preparing method thereof. The hydrogel is formed by self-assembly of multi-branched glycopeptides modified with hydrophobic cholesterol under physiological conditions through hydrophobic forces, pi-pi stacking, hydrogen bonds, and other forces. A glucosamine unit in the structure of the multi-branched glycopeptides can effectively inhibit tissue fibrosis caused by fibroblast proliferation so as to prevent formation of a postoperation scar, so that the hydrogel can be used as an anti-postoperation scar gel phase preparation. By introduction of the hydrophobic cholesterol, biocompatibility of the gel is enhanced, toxic and side effects and inflammation risks of the gel are reduced, and the self-assembly capability and stability of the hydrogel are enhanced. The hydrogel has advantages of high biosecurity, convenient operation, and the like.
