The Topsoil Quality Variation Under Different Reclamation Modes in Pasture Opencast Coal Mine of China

Abstract:

As the lack of topsoil resources, and the shortage of water resources, the ecological environment is extremely fragile in the pasture opencast coal mine area of China. Therefore, that the way to achieve the most efficient use of the limited topsoil resources in pasture area, plays a crucial role in land reclamation and ecological restoration. East II opencast coal mine in Datang, Inner Mongolia was taken as an example to analyze topsoil quality variation under different dump platform and slope reclamation modes in the pasture opencast coal mine area. The field investigation method was used in this paper. The study found that the mode "covering topsoil, overlying grass, grass grid, N fertilization, planting vanguard vegetation" in dump platform and "covering topsoil, overlying grass, grass grid, planting vanguard vegetation " in dump slope can lead to the best topsoil quality, though it still less than the original landscape topsoil quality level. The research can provide technical support and scientific basis for the pasture reclamation and ecological restoration.
