中文摘要	以亿利生态光伏电站3种不同立地条件的光伏电板阵列内沉积物为研究对象,利用激光衍射技术研究地表不同位置0~5cm沉积物粒度组成,计算平均粒径、标准偏差、分形维数等粒度参数。结果表明:(1)光伏区沉积物以细沙、中沙、极细沙为主。其中甘草光伏区还有少量的粉沙,其体积百分含量为2.93%,裸沙光伏区土壤细沙粒、中沙粒体积百分比分别为74.03%和23.24%,秸秆光伏区细沙粒、中沙粒颗粒体积百分比分别为82.76%和14.41%。(2)秸秆和甘草光伏区极细沙粒百分含量上升,分选性变差,峰态平缓,偏度近似对称,分形维数数值增大,但相比裸沙光伏区,甘草光伏区的标准偏差和峰态值有一定的规律,但秸秆光伏区的标准偏差和峰态值无明显规律。(3)挟沙气流受到光伏电板倾斜角的加速,对光伏电板板间、板下、基座三处位置的土壤颗粒粗细分配不均,且铺设秸秆不足以能使土壤颗粒的细粒组分朝良好趋势发展,种植甘草可以使土壤细粒组分增多。
英文摘要	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 0~5cm 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.
