“…As discussed above, HM contamination indeed significantly affected the bacterial community composition due to the different HM tolerances of different bacterial taxa. In this study, the main phyla were Proteobacteria, Actinobacteria, Acidobacteria, Chloroflexi, Planctomycetes, Bacteroidetes, Gemmatimonadetes, and Firmicutes, which was consistent with the dominant phyla observed in mining soil in some previous studies [77,78], suggesting that heavy metal stress is the main factor underlying the composition of soil bacterial communities in the mining area. Although types of mine soil varied from geological conditions, distribution of mineral resources, and mining activities, Proteobacteria, Actinobacteriota, Chloroflex, Acidobacterita, and Gemmatimonadota played important roles in determining the composition of bacterial communities in the mining environment.…”

Heavy metal (HM) contamination caused by mining and smelting activities can be harmful to soil microbiota, which are highly sensitive to HM stress. Here, we explore the effects of HM contamination on the taxonomic composition, predicted function, and co‐occurrence patterns of soil bacterial communities in two agricultural fields with contrasting levels of soil HMs (i.e., contaminated and uncontaminated natural areas). Our results indicate that HM contamination does not significantly influence soil bacterial α diversity but changes the bacterial community composition by enriching the phyla Gemmatimonadetes, Planctomycetes, and Parcubacteria and reducing the relative abundance of Actinobacteria. Our results further demonstrate that HM contamination can strengthen the complexity and modularity of the bacterial co‐occurrence network but weaken positive interactions between keystone taxa, leading to the gradual disappearance of some taxa that originally played an important role in healthy soil, thereby possibly reducing the resistance of bacterial communities to HM toxicity. The predicted functions of bacterial communities are related to membrane transport, amino acid metabolism, energy metabolism, and carbohydrate metabolism. Among these, functions related to HM detoxification and antioxidation are enriched in uncontaminated soils, while HM contamination enriches functions related to metal resistance. This study demonstrated that microorganisms adapt to the stress of HM pollution by adjusting their composition and enhancing their network complexity and potential ecological functions.

“…Research by Tian et al (2007) showed that elevated levels of HMs in soil can reduce the availability of essential nutrients such as nitrogen and phosphorus, leading to decreased plant growth and productivity. Yin et al (2023) concluded that HMs were the main limiting factors affecting the bacterial community structure in polymetallic mineral soils.…”

“…With economic development, especially with increasing irrational mining activities, a large number of abandoned lands have been produced (Wang et al 2018 a ), which has resulted in large‐scale deterioration of aboveground vegetation, soil and water pollution, and eco‐environmental degradation. Therefore, the ecological restoration of abandoned mining areas has become a research hotspot worldwide and is important for ensuring sustainable development (Jiang et al 2022; Nong et al 2022; Yin et al 2023).…”

“…Although the physicochemical properties of mining wastelands are markedly different from those of natural bedrock‐derived parent materials, the drivers of soil formation are the same, and understanding how these drivers interact is key for manipulating natural processes of soil formation toward desired ecosystem endpoints (Nyenda et al 2021). Soil properties change imperceptibly, resulting in changes in soil physicochemical properties and soil enzyme activities (Guo et al 2022; Yin et al 2023).…”

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.

Nine land types in the northern mining area (BKQ) (mining land, smelting land, living area), the old mining area (LKQ) (whole-ore heap, wasteland, grassland), and southern mining area (NKQ) (grassland, shrubs, farmland) of Xikuang Mountain were chosen to explore the composition and functions of soil bacterial communities under different habitats around mining areas. The composition and functions of soil bacterial communities were compared among the sampling sites using 16S rRNA high-throughput sequencing and metagenomic sequencing. α diversity analysis showed the soil bacterial diversity and abundance in the old mining area were significantly higher than those in the northern mining area. β diversity analysis demonstrated that the soil bacterial community composition was highly similar among different vegetation coverages in the southern mining area. Microbial community function analysis showed the annotated KEGG function pathways and eggNOG function composition were consistent between the grassland of the old mining area and the grassland of the southern mining area. This study uncovers the soil bacterial community composition and functions among different habitats in the mining areas of Xikuang Mountain and will underlie soil ecosystem restoration in different habitats under heavy metal pollution around the mining areas there.
