Claim 10:
11. A method of land reclamation and vegetation reconstruction in the strip mine dump, comprising:
constructing an ecological reconstructed sponge structure;
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 consisting of, from bottom to top,
a water-resisting layer having an initial thickness of 100-200 cm,
a water-containing layer having an initial thickness of 150-250 cm, having a permeability coefficient of 10-20 m/d, and consisting of a mixture of sand, soil, and fly ash that has been subjected to a degree of compaction of between 800 and 900 kPa,
and a topsoil ecological layer having an initial thickness; and
periodically using ground penetrating radar to evaluate the thickness and moisture content of the topsoil ecological layer and the water-containing layer.
