The invention provides a soundproof heating wood-plastic wall plate. The soundproof heating wood-plastic wall plate comprises a base plate layer made from a wood-plastic material, the lower surface of the base plate layer is provided with a heating layer, a soundproof layer is arranged at the bottom of a heat insulation layer which is arranged at the bottom of the heating layer, and the bottom of the soundproof layer is connected with a bottom plate made from the wood-plastic material. One end of the base plate layer is provided with a tenon while the other end of the base plate layer is provided with a mortise matched with the tenon. By arrangement of the heating layer, indoor heating in winter can be realized by the wood-plastic wall plate; by the soundproof layer in the wood-plastic wall plate, noise can be effectively isolated. The wood-plastic wall plate has advantages of convenience in mounting, energy saving and environmental friendliness and also has functions of indoor heating in winter and external noise isolation, thereby being functional versatile.
