Ecological restoration method for waste dump of high and cold grassland mining area

The invention provides an ecological restoration method for a waste dump in a high and cold grassland mining area. The method comprises the steps that a biological crust compound serves as an inoculation material to be applied to the surface of to-be-remedied soil, sun shading and progressively-decreased water supplementing are conducted, and ecological remediation is completed; wherein the biological crust compound is composed of algae crust and moss crust. According to the method, the composite biological crust material and the decreasing type water supplementing culture method are adopted, the inoculation survival rate of the biological crust under the real field stress is increased, the soil habitat of the high and cold mining area can be rapidly and remarkably improved, and meanwhile overall, healthy and sustainable restoration of a vegetation-soil system is promoted. 本发明提供了一种高寒草原矿区排土场的生态修复的方法。该方法包括：将生物结皮复合物作为接种材料施加于待修复土壤表面，进行遮阳并递减式补水，完成生态修复；其中，生物结皮复合物由藻结皮和藓结皮组成。本发明采用复合的生物结皮材料及递减式补水培养的方法，提高了生物结皮在野外真实的逆境下
