The invention relates to cement-based materials and particularly discloses a basalt fiber reinforced cement based material and a preparation method therefor. The basalt fiber reinforced cement based material contains the following ingredients: 400-800kg/m of cement, 150-330kg/m of active mineral admixture, 800-1,500kg/m of fine aggregate, 10-40kg/m of water reducing agent, 0.01-0.05kg/m of setting retarder, 0.5-3.0% (volume percent) of basalt fibers and 0.2-1.0% (mass percent) of fiber surface modifier. According to the basalt fiber reinforced cement based material and the preparation method therefor, through optimizing a formula, the compactness of the material is improved, meanwhile, the property of an interface layer between the basalt fibers and a cement bonding material is improved, and the interfacial bonding strength is improved. The structure and mechanical properties of the basalt fiber reinforced cement based material disclosed by the invention are improved relatively greatly, and the compression st
