Abstract：Inorder toclarifytheinfluence offlatsingle-axis low-piletrackingphotovoltaicpanelsonthespatial distribution characteristicsofsoilnutrients inphotovoltaic powerstations insandyareas，thesoil underflatsingle-axis low-piletrackingphotovoltaicpanels in the vegetationnatural restorationareaof photovoltaic power stations in typical sandy areas of western Inner Mongolia was taken asthe research object.The photovoltaic panels were divided into 4 positions：inter-panel （IP），front-panel （FP），back-panel（BP）and under-panel（UP）.At the same time，5 soil depths of0 to10，10 to 20，20 to 40 ，40 to 60 and 6O to 1OO cm were set at each position. The bare sandy land without any photovoltaic measures inthe photovoltaic power station was used as thecontrol（CK）.Through correlation analysis andone-wayanalysis ofvariance，the horizontaland vertical distributioncharacteristicsofsoilnutrientsundertheflat uniaxial low-pile tracking photovoltaic panel were explored，and the principal component analysis was further used to evaluatethesoil qualityat diferent locationsinthe field.Theresultsshowed that theconstructionof tracking photovoltaic panels would reduce the atmospheric temperature and atmospheric humidity inthe photovoltaic field.The soilmoistureandsoilbulkdensityatdifferentpositionsof theelectricboardshowedalawofincreasingwiththeincrease of soil depth.Theconstructionof tracking photovoltaic panels would increasethecontentofsoil nutrients.Thecontents of soilavailablenitrogen，organicmatterandavailablepotassiumdecreased withtheincreaseofsoil depth.Thecontent ofavailable phosphoruschanged littleand fluctuates between diferent depths.Thesoil qualityof the tracking photovoltaic panel area was higher than thatof the CK position，among which the soil qualityof IP，FPand RP positions was beter，andthe soil qualityof UPandCK positions was poor，which showed that theconstruction and operation of tracking photovoltaic panels in sand area improved the soil qualityinthe field area.Above results provided theoretical supportfor the ecological restoration of photovoltaic power stations in sandy areas.
