“…Previous studies mainly focused on surface layer (P. Li et al, 2019; Sun et al, 2021). Result indicated here that the effects of restoration patterns on OC contents in deeper layers (30–50 cm) were more significant.…”

Vegetation restoration of land post‐mining can strengthen the development of soil aggregates and promote the accumulation of soil organic carbon (SOC), and Microbial restoration such as Arbuscular mycorrhizal fungi (AMF) can significantly improve the effect of vegetation restoration. However, the effects of different recovery modes (microbial and natural restoration) on soil macroaggregates development and the carbon flows of the organic carbon (OC) have been less studied on reclaimed mine soil. A 4‐year field experiment was conducted on opencast coal reclaimed areas in Inner Mongolia grassland, and three recovery modes were set up: artificial restoration, artificial restoration (inoculated with AMF) and natural restoration. Results showed that compared with the natural restoration, artificial restoration and AMF inoculation increased the OC, total glomalin‐related soil proteins (TGRSP) contents and the value of δ13C in macroaggregates (>0.25 mm) in deep soil (30–50 cm). The shallow roots were the most likely starting points of carbon flow in the natural recovery area surface soil, and artificial restoration inoculation with AMF increased the carbon flows between all levels of aggregates in deep soil, showing a carbon flow pattern from macroaggregates to microaggregates (<0.25 mm). Moreover, significant correlations among the TGRSP, SOC content, and δ13C value were recorded, indicating the SOC sequestration and stability of reclaimed mine soil were potentially associated with TGRSP. In summary, both natural restoration and artificial restoration had advantages and disadvantages on reclaimed mine soil, but the artificial restoration inoculation with AMF showed great potential in promoting the aggregate carbon flow and persistent SOC accumulation.

“…In general, the results of this study showed that soil nutrient levels increased over the restoration period. Among various soil parameters, soil C, N, and P (Ma et al 2020), macrometallic nutrients (Nyenda et al 2021) and enzymes (Sun et al 2021) are often considered.…”

The space‐for‐time method was used to track changes in heavy metals (HMs), selected physicochemical properties and soil enzyme activities at different restoration ages, that is 5, 10, and 25 years (named R5, R10, and R25, respectively) and in a natural forest (NF, age > 100 years, as the control) in the Daxin manganese (Mn) wastelands in China. The results showed that the HM concentrations decreased over time, with Mn exhibiting the highest concentration, followed by zinc, copper, and cadmium; all the studied sites exhibited heavy pollution levels based on the Nemerow multifactor index, with a very high potential ecological risk (RI) level in R5, moderate RI in R10 and R25, and low RI in NF; generally speaking, the soil physicochemical properties improved, with the exceptions of the available phosphorus (AP) and calcium (Ca) levels; the soil enzymes generally exhibited the highest activities in R25, while the activity of catalase showed a significant (p < 0.05) decrease over time; both the HM concentrations and physicochemical properties showed significant correlations with soil enzyme activities; redundancy analysis showed that soil pH and HM species should be given more attention in R5 for vegetation recovery; and the HM concentrations, soil moisture content, and ammonium nitrogen, total nitrogen, potassium, and magnesium levels might be the limiting factors for plant colonization in early restoration periods, while the AP, total phosphorus, and Ca levels might be the limiting factors in later restoration periods. The obtained results will provide guidance for the restoration of abandoned Mn‐polluted areas.

“…However, due to problems such as the long period and wide spatial scale of artificial vegetation restoration, there are currently few evaluations of the restoration effects of coal mining subsidence areas. In addition, the soil conditions of coal subsidence areas are poor [19] , the community structure of artificial ecosystems is relatively simple, and the stability of the ecosystem is low, making it highly sensitive to emergencies and human activities. Therefore, studying the dynamic changes in vegetation coverage in Jiawang District is particularly necessary and significant for exploring artificial vegetation restoration and ecological environment governance.…”
