中文摘要	以库布齐沙漠南缘光伏电站表土为研究对象,利用激光衍射技术分析研究了地表0 ~ 5 cm层沉积物粒度特征,探讨光伏电站对风蚀颗粒粒度的影响。结果表明:光伏电站内沉积物以细砂、中砂为主。光伏电板的阻滞作用使得板下极细砂、细砂含量升高,中砂含量降低。与裸沙丘相比板下与板间分选性变好,板下颗粒细化,板间颗粒粗化,峰态偏离正态,向负偏发展,颗粒频率分布曲线变宽,累积频率曲线依次变陡。光伏电站内迎风方向(东南向西北方向)电板区域沉积物含量波动显著,频率较高,平均粒径较背风方向小,迎主害风方向颗粒出现粗化趋势。背风方向(西南向东北方向)沉积物含量波动频率明显下降,平均粒径较迎风方向大,背风方向颗粒出现细化趋势。北向南方向电板区域沉积物粒径逐渐增大,颗粒出现细化趋势,由光伏电站外缘延至光伏电站内部极细砂、细砂颗粒堆积程度逐渐增大。光伏电站迎风方向沉积物粗粒化现象尤为严重,需要在光伏电站周围、主要在迎风方向建设防护措施,来降低电站内颗粒粗粒化现象以及板间堆积现象的发生程度。
英文摘要	Taking the topsoil samples from the photovoltaic power station in the southern edge of Kubuqi Desert, the particle size characteristics of the sediments in the 0 - 5 cm surface layer were analyzed by means of laser diffraction technology in order to explore the influence of photovoltaic power station on the particle size by wind erosion. The sediments in the photovoltaic power station were mainly composed of fine sand, medium sand and extremely fine sand. The retardation of the photovoltaic panel increased the percentages of extremely fine sand and fine sand, and decreased that of medium sand under the panel. Compared with the bare sand dunes, the sorted behavior of practical was improved under- and inter- panel. The particle size under panel was reduced, but that inter- panel was increased. The peak deviated from normal state and developed toward negative state. The distribution curve of particle frequency widened and the cumulative frequency curve became steeper successively. The sediment content of the photovoltaic power station in the windward direction (southeast to northwest) of panel area fluctuated significantly. With higher frequency, the average particle size was smaller than that in the leeward direction. The particle size demonstrated a growing tendency in the direction of main wind hazard. The fluctuation frequency of sediment content in the leeward direction (southwest to northeast) dropped drastically, with a particle refinement trend, and the mean particle size was larger than that in the windward direction. The particle size of the sediments in the panel area gradually increased from north to south, and grew finer. From the outer edge to the inside of the photovoltaic power station, the accumulation degree of extremely fine sand and fine sand particles gradually rose. The phenomenon of coarse graining of sediments in the windward direction of photovoltaic power station was particularly serious. It is necessary that building protective measures around the photovoltaic power station and mainly in the windward direction to reduce the occurrence of particle coarsening and stacking phenomena between panels.
