The invention discloses a strip mine area topsoil reconstruction mode and application, and the strip mine area topsoil reconstruction mode combines local natural materials of sandy loess, aeolian sandy soil and arsenic sandstone in Shanxi, Shaanxi and Mongolia strip mine areas to construct a layered soil body according to the national land reclamation technology standard. The reconstructed soil body with the soft sandstone interlayer thickness of 20 cm is screened out by comparing the soil moisture of the reconstructed soil body with different soft sandstone interlayer thicknesses and the alfalfa growth condition through an indoor test, a soil column test and a field test, the water storage capacity of the soil body is increased, plant growth is promoted, and the reconstructed soil body can serve as an optimal mode for reconstructing the surface soil body of the mining area in the area. According to the reconstruction mode, the water retention effect of the soil body is remarkably improved, water evaporation
