The utility model discloses an aluminum, titanium, nickel and stainless steel four-layer composite plate for an LNG (liquefied nature gas) transport ship. The composite plate comprises an aluminum plate layer, a titanium plate layer, a nickel plate layer and a stainless steel plate layer which are adhered one another, wherein the aluminum plate layer has a thickness of 13mm, the titanium plate layer has a thickness of 2mm, the nickel plate layer has a thickness of 2mm and the stainless steel plate 304L layer has a thickness of 20mn. The composite plate is manufactured by adopting the explosive welding technology. The four layers of different materials can be arranged to serve as gradient materials with thermal conductivity by fully considering the mechanical properties of mutual combination of the four layers of different materials of the composite plate during manufacturing by explosive welding and the difference of thermal conductivity of the four layers of different materials, the heat conduction of a manu
