“…The large-scale construction of PV panels can cause heterogeneity in environmental factors, such as light, precipitation, and wind speed. This can lead to microhabitat climate changes that may affect ecosystems ( Li C. et al, 2023 ; Li X. et al, 2023 ). The study found that light intensity varied significantly ( p < 0.05) across different locations, with the order being CK > FP > RP > UP.…”

“…In some small-scale habitats, light may be a key factor driving bacterial community aggregation ( Li C. et al, 2023 ; Li X. et al, 2023 ). The correlation between the relative abundance of Proteobacteria and light intensity was significant in the EP sample plot.…”

“…UPARSE version 7.1 1 was used to group operational taxonomic units (OTUs) with a 97% similarity criterion and to detect and remove chimeric sequences. RDP Classifier version 2.2 was applied to compare the taxonomy of each OTU representative sequence to the 16S rRNA database (e.g., Silva v138) with a confidence threshold of 0.7 ( Li X. et al, 2023 ). OTUs were eliminated if they did not contain three reads in at least two samples or were not assigned to a bacterial phylum ( Yang et al, 2022 ).…”

Solar photovoltaic (PV) power generation is a major carbon reduction technology that is rapidly developing worldwide. However, the impact of PV plant construction on subsurface microecosystems is currently understudied. We conducted a systematic investigation into the effects of small-scale light stress caused by shading of PV panels and sampling depth on the composition, diversity, survival strategy, and key driving factors of soil bacterial communities (SBCs) under two vegetation restoration modes, i.e., Euryops pectinatus (EP) and Loropetalum chinense var. rubrum (LC). The study revealed that light stress had a greater impact on rare species with relative abundances below 0.01% than on high-abundance species, regardless of the vegetation restoration pattern. Additionally, PV shadowing increased SBCs’ biomass by 20–30% but had varying negative effects on the numbers of Operational Taxonomic Unit (OTU), Shannon diversity, abundance-based coverage estimator (ACE), and Chao1 richness index. Co-occurrence and correlation network analysis revealed that symbiotic relationships dominated the key SBCs in the LC sample plots, with Chloroflexi and Actinobacteriota being the most ecologically important. In contrast, competitive relationships were significantly increased in the EP sample plots, with Actinobacteriota having the most ecological importance. In the EP sample plot, SBCs were found to be more tightly linked and had more stable ecological networks. This suggests that EP is more conducive to the stability and health of underground ecosystems in vulnerable areas when compared with LC. These findings offer new insights into the effects of small-scale light stress on subsurface microorganisms under different vegetation restoration patterns. Moreover, they may provide a reference for optimizing ecological restoration patterns in fragile areas.
