The two-year observation data of the three monitoring stations inside and outside Qinghai Gonghe Photovoltaic power plant from January 2019 to December 2020 was compared to analyze the characteristics of soil temperature changes inside and outside the photovoltaic power plant. The results showed that the photovoltaic power plant had the function of heat insulation and heat preservation, and had a greater impact on shallow soil. Specifically speaking, the photovoltaic power plant is the cold source in spring, summer and autumn, and the cooling effect on soil is the strongest in spring; the station offers insulation to the soil, and the impact of the station on soil temperature decreases as the distance from the center of the photovoltaic station increases.
