Claim 5:
6. A method of land reclamation and vegetation reconstruction in the strip mine dump, comprising:
combining an ecological reconstructed sponge structure with a ground penetrating radar to monitor thicknesses and moisture content of soil layers;
wherein, the ecological reconstructed sponge structure of a strip mine dump is a three-layered sponge ecological structure arranged on a groundmass layer of the dump, and the three-layered sponge ecological structure comprises, from bottom to top, a water-resisting layer, a water-containing layer, and a topsoil ecological layer;
wherein
a thickness of the water-resisting layer is 100-200 cm,
a thickness of the water-containing layer is 150-250 cm,
the water-containing layer comprises a mixture of sand, soil, and fly ash that has been subjected to a degree of compaction,
the degree of compaction is 800-900 kPa, and
a permeability coefficient of the water-containing layer is 10-20 m/d.
