The present invention provides a biodegradable sheet and a preparation method thereof, relating to the technical field of biodegradable sheets. The biodegradable sheet is made of biodegradable polymers, and the materials of the biodegradable sheet include polylactic acid, polyhydroxyalkanoate polymer, food-grade starch, modified cellulose, filler and polycaprolactone. The components of the biodegradable sheet by mass percentage are: food-grade starch 50–60%, polylactic acid 10–20%, polyhydroxyalkanoate polymer 2–5%, modified cellulose 5–8%, polycaprolactone 2–10%, filler 5–10%. The present invention solves the problems that the preparation method of traditional degradable sheets is complicated, the degradation effect is ordinary, and the degradation period is long due to poor degradation effect after use, which reduces the environmental performance of the sheet to a certain extent.
