Abstract [Background] During the construction of photovoltaic electric field, the excavation, dumping and rolling of the original surface inevitably destroy the soil and vegetation of the construction area. Through the study on the disturbance of soil environment and vegetation caused by the construction of photovoltaic power station, this paper tried to provide technical support for the ecological protection during the construction of photovoltaic power plant in the Gobi Desert Area in the Hexi corridor of Gansu.[Methods] The study took 6 typical photovoltaic power stations in Wuwei, Zhangye and Jiayuguan cities from east to west in the Gobi Desert Area in the Hexi corridor in Gansu as the research object. The disturbances of photovoltaic power station construction on soil environment and vegetation were studied by using the methods of field observation, inspection, and soil and water conservation monitoring data.[Results] 1) There was little difference in soil pH value, total nitrogen, total phosphorus, total potassium, organic matter and available phosphorus in the disturbed area between photovoltaic panels and the undisturbed area outside the photovoltaic power station, and the disturbance to the influence of soil nutrient was not obvious. 2) During the construction of photovoltaic electric field, the original vegetation and the surface crust were destroyed greatly, and the surface crust was damaged, which aggravated soil erosion and dust, and even caused dust storms. The destruction of vegetation reduced the coverage of vegetation and caused the deterioration of ecological environment and the decrease of plant population diversity. 3) During the operation period, the photovoltaic panel collected rainwater and the abandoned water for cleaning the photovoltaic panel, which increased the soil moisture content of the disturbed land between the photovoltaic panels and was conducive to vegetation restoration.[Conclusions] It is suggested that photovoltaic power station construction should give priority to photovoltaic modules with high photoelectric conversion efficiency, and spiral steel pipe pile foundation should be selected as the support foundation under geological conditions to reduce the disturbance range and intensity to the surface. The consciousness of environmental protection must be established in achieving the civilization construction.
