Restoration method for mine wasteland

The invention discloses a restoration method for mine wasteland. The method comprises the following steps: more than one row of fish-scale pit layers are dug on the mine wasteland, vegetation is planted in the fish-scale pit layers, water retention, soil conservation and fertilizer conservation for the mine wasteland are realized by fish-scale pits, and by means of the planted vegetation, heavy metal elements can be adsorbed and soil can be stabilized, so that the ecological system of the mine wasteland is restored. According to the method, the topsoil obtained by excavation of the fish-scale pits and the ecological restoration matrix are mixed and then backfilled, necessary elements are provided for growth of the plants in the pits, the ecological restoration matrix is relatively high in water retention rate and soil retention rate and rich in organic elements for plant growth, the restoration method is low in cost and good in economic benefit, the mine is beautified, and meanwhile, heavy metal pollution to
