The invention discloses an iron ore waste-rock yard land rehabilitation integral regulation method comprising the following steps: cleaning large size rocks and foreign materials on the waste-rock yard land surface, keeping original roads and public & auxiliary facilities, and leveling the waste-rock yard land and slopes and rolling out; keeping and reconstructing original draining systems according to plans, and newly constructing water supply and power supply facilities; building a retaining wall, an apron wall, a waterway, and/or catch water drain on a slope with easy water and soil floating; covering an iron ore open pit mining erosive rehabilitation pile-up topsoil layer with a thickness of at least 40cm on a compacted platform and a slope, leveling and naturally depositing the soil;building a sprinkling facility on a platform, and covering a humus soil of at least 5cm on a planting soil surface layer, and planting city greening normal tree species; digging planting pits with theline spacing of at least 1.5m*1.5m on other platforms and smooth slopes, setting an impervious layer on the bottom, refilling the rehabilitation pile-up topsoil, and finally planting fast-growing forest trees. The iron ore waste-rock yard land rehabilitation integral regulation method is low in rehabilitation cost, high in land treatment rate, and stable in post-rehabilitation geology, and has sustainable benefits.
