The invention provides an oriented arrangement method for metal nanowires. The oriented arrangement method comprises the steps of: preparing the metal nanowires, and storing the metal nanowires by using an alcoholic solvent after cleaning; preparing sheet substrates, cleaning the surfaces of the substrates, and performing ozone treatment of the substrates for 5-10 min; and fixing the processed substrates at the clamp head of a lift machine in pairs, adding the metal nanowires or metal nanowire solution in the 70-95-DEG solvent by dropping, and putting the clamp head in the solvent to lift, so that a conductive film is obtained. The oriented network film prepared by the preparation method in the invention is obvious in overall orientation and has high conductivity and high transparency; furthermore, large-area orientation and multi-layer orientation can be realized; operation is simple; and the cost is low.
