Abstract：Photovoltaic （PV） power stations are expanding rapidly as a clean energy source，yet their ecological impacts on desert ecosystems remain insufficiently understood. In this study，we examined the efects of a PV power station，operating for seven years in Hongshagang，Minqin，Gansu Province，on vegetation characteristics and soil physicochemical properties. And，three site types beneath PV panels（BX），between PV panels （BJ），and an undisturbed control area（CK）were investigated.The results showed that the Margalef richness index，Shannon-Wiener diversity index，Simpson dominance index，vegetation cover，and aboveground bio mass were higher in BX and CK than in BJ. The soil moisture content，organic mater，available potassium， and available phosphorus increased in BX and BJ，whereas pHand electrical conductivitydecreased Vegetation coverage and aboveground biomass were significantly negatively correlated with soil electrical conductivity. Overall，after seven years of operation，the PV power station improved soil physicochemical properties and enhanced species diversity and biomass accumulation.These findings provide valuable insights into the ecological effects of PV development in desert regions，offering guidance for sustainable PV station management and ecological restoration.
