The invention provides a borrowed soil layer structure based on river and lake bottom mud and phosphorite solid waste and a preparation method. The soil layer structure sequentially comprises a borrowed soil surface layer, a middle permeable layer and a borrowed soil base layer from top to bottom, and the contact surface between every two layers of borrowed soil layer structures is of a zigzag transition structure. The river and lake desilting bottom mud is modified and improved by utilizing industrial solid wastes such as phosphorus slag, phosphogypsum and steel slag to be used as vegetation concrete borrowed soil, the acid-base property of the borrowed soil meets the vegetation growth requirement, continuous nutrition supply can be provided for vegetation, the method has the technical advantages that raw materials are easily available, the process is simple, economical efficiency is excellent and ecological environmental protection is achieved, and the technical problems of high cost of vegetation concrete
