The invention relates to the field of mine soil improvement, and particularly discloses a soil improvement matrix suitable for ecological restoration of mines and a preparation method of the soil improvement matrix. The soil improvement matrix is prepared from the following raw materials in parts by weight: 15 to 35 parts of peat, 8 to 12 parts of phosphogypsum, 0.05 to 0.15 part of polyacrylamide, 80 to 100 parts of regenerated waste resources, 20 to 30 parts of urea and 5 to 10 parts of microbial agent. The soil improvement matrix can improve the local environment of plant growth in mining wasteland, provides excellent environment and nutrients for rapid growth of plants, improves the survival rate of plants and the ecological restoration rate of mines, and compared with a traditional different soil covering technology, the soil improvement matrix not only fundamentally solves the problem of plant site, but also improves the ecological restoration rate of the mines. The method saves land resources, and is s
