The invention belongs to the technical field of MOF membranes, and particularly relates to an MOF membrane based on a Cu-BTC/cellulose composite material and a preparation method of the MOF membrane. The MOF membrane based on the Cu-BTC/cellulose composite material is prepared by coating microcrystalline cellulose with Cu-BTC to prepare the Cu-BTC/cellulose composite material, mixing the Cu-BTC/cellulose composite material with a membrane-making mother agent, a pore-making agent and a homogeneous membrane material to prepare a homogeneous membrane casting solution, and coating, winding, curing and drying the homogeneous membrane casting solution to prepare the MOF membrane based on the Cu-BTC/cellulose composite material. The prepared Cu-BTC/cellulose composite material has a submicron rough surface and a slender fibrous structure, the MOF membrane prepared from the Cu-BTC/cellulose composite material has richer pore and channel structures, the accessibility of active sites is increased, and the gas permeabil
