Dataset on the Interactions and Evolution of Soil-Plant-Microbial Dynamics in the Ecological Restoration of Mineral Black Clay Covered Dump

In the feasibility study on using mineral black clay to replace surface soil for ecological restoration of an open-pit mining dump, various bioremediation methods were applied to assess their impact. These included a single biological treatment group (S-ERB), a three-time biological treatment group (F-ERB), and a control group (N-ERB). The study aimed to examine how different frequencies of bioremediation influenced the effectiveness of black clay in ecological restoration. Observations were made on the diversity and distribution of surface vegetation across the different treatment areas, differences in soil nutrient structures were analyzed, and the microbial community structure and metabolomics characteristics were compared among the treatment groups.
