The environment-friendly composite board is composed of a base board and a PE (polyethylene) film arranged on the surface of the base board, wherein the base board comprises the following components in percentage by weight: 50-80% of jute fiber, 20-50% of low-melting-point fiber and 0-30% of Alpinia zerumbet fiber. According to the environment-friendly composite board for home decoration, the base board is prepared by compounding low-melting-point fibers, jute fibers and Alpinia zerumbet fibers, the food grade colored PE film is covered on the base board, and no other components are added, thereby ensuring that the product is free of other harmful chemical substances and causing no harm to the body; and meanwhile, the jute fibers bring favorable moisture absorption and air permeability, and have bacterium resistance and mite prevention effects. The environment-friendly board is light in weight and high in hardness, can be used instead of wallpaper, paint and other decorative materials, and can be directly used in places to be decorated, such as walls, roofs and the like. The preparation method of the environment-friendly composite board is simple in procedures, convenient to operate and easy to realize industrialization; and the gram weight of the prepared product can be up to 100-300 g / m<2>, and the thickness is 0.3-5 mm.
