Although the reclamation activity could effectively promote the ecological service function of mining areas, the microbiological mechanism of functional reconstruction of reclaimed soil is still unclear. Clarifying how reclamation affects the characteristics, assembly mechanisms, and carbon sequestration functions of soil bacterial communities, is crucial for reshaping the ecological self-sustaining capacity of mining areas. To shed light on this purpose, combined with zero model analysis, MiSeq high-throughput sequencing and qPCR SmartChip technologies were used to explore the assembly processes and carbon sequestration functional variations of soil bacterial community in Dongtan mine area at four reclamation years (reclaimed 9 a, 12 a, 15 a, and 18 a). The results showed that: ① Reclamation activity and time presented significant impacts on soil physicochemical properties and enzyme activities. Soil pH, ammonium nitrogen (AN), catalase (CAT), and alkaline phosphatase (PO) showed the significant increasing trends with the incremental reclamation time (P |
