A study of the effect of mine exploitation on alpine grassland and its vegetation restoration technology

The rehabilitation of abandoned mining areas has become one of the urgent tasks faced by China. To tackle the bottleneck of the constraints on the natural environment such as short plant growth period, slag gravelly nature, looseness and poor vegetation of the Tibetan Plateau, the study of the remediation process of the mining wasteland in ecologically fragile areas has summarized the typical mine waste of the Tibetan Plateau. The ecological restoration of the land and the governance model of vegetation reconstruction concluded and screened out key technologies to provide technical reference for the geological environment treatment and land reclamation in the alpine high-altitude mining areas.
