The sediments in the photovoltaic panel array of Yili Eco-photovoltaic Power Station under three different site conditions were taken as the research samples. The particle size composition of 0~5 cm surface layer of sediment at different locations was studied by laser diffraction technology. The particle size parameters such as average particle size, standard deviation and fractal dimension were calculated and analyzed. The results show that:(1)the sediments in photovoltaic area are mainly composed of fine sand, medium sand and very fine sand, there is a small amount of silt in the photovoltaic area of licorice, volume percentage of silt is 2.93%, the volume percentages of fine sand and medium sand in bare sand photovoltaic area are 74.03% and 23.24%, respectively, and the volume percentages of fine sand and medium sand in straw photovoltaic area are 82.76% and 14.41%, respectively;(2)compared with bare sand photovoltaic area, the standard deviation and peak value of liquorice photovoltaic area have the some effect, but the standard deviation and peak value of straw photovoltaic area have no obvious regularity;(3)the sediment-laden air flow is accelerated by the inclination angle of photovoltaic panels, and the distribution of soil particles is uneven in the three locations of photovoltaic panels, under panels and pedestals, and the straw laying is not enough to make the fine-grained components of soil particles develop towards a good trend. Planting licorice can increase the fine fraction of soil.
