Ecological repairing method suitable for mines in arid area

The invention discloses an ecological repairing method suitable for mines in an arid area, and belongs to the technical field of ecological repairing. Firstly, by arranging a water storage system, slope runoff can be effectively collected and stored, slope wash is reduced, a water source is provided for dry season irrigation, the problem that there is a lack of water for repairing the mines in thearid area is solved, and rainfall flood is reasonably utilized. In addition, by applying microorganism fertilizers, the green manure plant decomposition can be promoted, organic matter in soil can beincreased, the organic matter can be chelated with heavy metal ions in the soil, and therefore the content of the heavy metal ions in the soil is reduced. Meanwhile, trees selected to be planted havehigh resistance to heavy metals, easily survive in the mines high in heavy metal content, have no strict requirements for the soil and are high in air pollution resistant capacity, and leaves can absorb toxic gases and dust ac
