Vegetation restoration is crucial for improving the ecological environment of mining areas, which could promote the development of reconstructed soil, thus regulating biogeochemical cycles, and exerting ecosystem functions. Therefore, it is essential and necessary to conduct in-depth research on the impact of vegetation restoration on soil microbial communities in open-pit mining areas. In this study, surface soil samples were collected from six typical reclamation plots, including bare land (CK), Medicago sativa (GL), Hippophae rhamnoides (BL), Pinus tabulaeformis (CF), Populus tomentosa (BF), and Populus tomentosa + Pinus tabulaeformis (MF), located in the eastern waste dump of Heidaigou mining area of Zhungeer Banner, Inner Mongolia. High throughput sequencing, co-occurrence networks, and correlation analysis were used to explore the influential mechanism of vegetation types on soil abundant, rare bacterial and fungal community structural composition and diversity. Results showed that ① there were significant differences in the effects of different vegetation restoration types on soil physicochemical properties and enzyme activity (P
