沙戈荒地区光伏建设对土壤微生态系统影响的研究进展OA

With the large-scale construction of photovoltaic(PV)power stations in desert,Gobi,and Barrenland(referred to as"DGB")regions,increasing attention has been paid to the evolution of the soil environment in PV construction areas.This paper integrates findings from empirical investigations conducted in China,systematically reviews the patterns of changes in soil physical and chemical properties and the succession characteristics of the soil micro-ecosystem caused by variations in the surface microclimate beneath PV panels in DGB regions,and summarizes successful models for the synergistic and healthy development of the PV industry and soil ecology.Results indicate that the shading,rainwater harvesting,and wind-redirecting effects of PV panels can significantly alter microclimatic conditions such as light,heat,water,and wind beneath the panels,thereby improving soil physical properties,including temperature,humidity,and particle composition,as well as soil chemical properties,such as nutrient and organic matter content.The synergistic effects of changes in surface microclimate and soil physicochemical properties can promote beneficial changes in the soil organic carbon pool,microbial diversity,and biomass.The"PV+ecological restoration"model,which features clean energy generation above the panels and ecological restoration beneath them,demonstrates considerable potential for synergistically advancing clean energy production and the restoration of fragile ecosystems.Future research should focus on the development of mathematical models describing the regulation of surface microclimate and soil physicochemical properties by PV,the dynamic mechanisms underlying soil micro-ecosystem restoration,and the optimization and intelligent management of key technologies for the"PV+ecological restoration"model.These efforts will provide scientific support for achieving high-quality,synergistic,and healthy development of the PV industry and the soil ecological environment.
