“…The analysis of microbial communities between and under various types of PV panels at Gonghe PV power station, Qinghai Province, has allowed researchers to examine the community abundance, diversity, structure, and distribution characteristics of soil bacteria and archaea. The conclusion drawn from this analysis is that PV stations have minimal impact on the community structure of soil bacteria and archaea ( Wu C. et al, 2022 ; Wu W. et al, 2022 ; Yuan et al, 2022 ). However, none of the previous studies have examined the response of soil microbial communities to small-scale light gradients caused by shading from PV modules under different vegetation restorations, nor have they investigated the vertical distribution of bacterial communities.…”

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.

“…More than 90% of precipitation occurred from May to September (Yue et al, 2021). The annual sunshine is about 2772 h and the average temperature is 4 C. Local soil types can be divided into three main types: grassland soil, eolian sandy soil, and saline alkali soil (Yuan et al, 2022). The types of vegetation are mainly shallow-rooted plants, like Achnatherum splendens, and fringed sagebrush (Wei & Wu, 2011).…”

Global drylands are experiencing booming development of centralized photovoltaics (PV), which aims to address the dual challenges posed by climate change and energy transformation. In dryland areas with large‐scale deployment of solar PV infrastructure, vegetation was reported to experience drastic changes. However, the long‐term dynamic changes and driving mechanisms have not been thoroughly studied yet. Quantitatively distinguishing the disturbances of climate change and PV plant deployment on vegetation change is the key to understanding the environmental impact of clean energy development and formulating adaptive ecological recovery measures. To understand this, we selected the Gonghe solar power project in northern China, one of the largest dryland PV plants in the world, as a case study. Specifically, satellite‐derived Normalized Difference Vegetation Index (NDVI) and meteorological data from ground stations were used to analyze the changing patterns of vegetation growth and climatic factors. The relative contributions of climatic factors and PV plant deployment to NDVI change were quantified by multiple regression analysis. The results indicated that vegetation has increased gradually since 2000, with the rate of vegetation recovery doubled during the PV expansion period. From 2013 to 2020, climate change was the main driver of increased vegetation (56%), followed by the expansion of solar PV infrastructures (44%). Vegetation inside PV arrays increased 1.4 times faster than outside, mainly because the PV panels improve the efficiency of rainwater utilization in summer and reduce the negative impact of excessive sunlight in the growing season. In addition, vegetation management practices like grazing can further enhance carbon sequestration and create sustainable livelihood opportunities, achieving sustainable economic, social, and ecological development. The novelty of the study lies in the proposed framework to quantify the impact of solar PV programs on vegetation in dryland allowing easy interpretations of vegetation dynamics under clean energy development and climate change, which provide scientific references for clean energy planning and ecological recovery in arid areas.

This study analyzes the dynamic variation and patterns of Soil Moisture (SM) content in Gonghe photovoltaic (PV) industrial park in Qinghai Province based on the measured data and discusses the impact of PV development on SM content and its effects. The results show that the PV panel has a humidification effect on the soil. The annual average SM content in the 10 cm layer under the fixed trackers (FIX) PV panel increases by 14.34%, and the SM under the Oblique Single-Axis (OSA) PV panel increases by 10.26%. The humidification effect of the fixed axis PV panel is greater than that of the inclined uniaxial PV panel. Different shading of PV panels will lead to significant spatial variation of SM, and the SM under and between PV panels is significantly different in vegetation growing season.
