中文摘要	[目的]研究光伏电站内芦苇沙障对风沙流的风速、输沙量及其沙粒分布的影响,为中国北方风沙区光伏电站沙害防治提供理论依据。[方法]通过野外观测库布齐沙漠200MWp光伏电站铺设芦苇沙障后的风速(20,50,100,200,310cm)和近地表030cm高度输沙量,分析风速廓线、地表粗糙度、摩阻风速、平均跃移高度、防风作用、固沙效益等指标的变化规律。[结果]①芦苇沙障风速廓线呈对数函数分布,相关系数在0.99以上,芦苇沙障相对于裸沙地表粗糙度提高了3.47~3.79倍,摩阻风速增加了1.39~1.54倍,防风作用最大值出现在20cm高度处,为21.72%。②总输沙量芦苇沙障仅为裸沙的6.95%,总体固沙效益为93.05%,裸沙90%以上的输沙量集中于08cm范围,而芦苇沙障在此高度范围内输沙量占总输沙量的51.39% ,芦苇沙障的风沙流结构有向上层移动的趋势。[结论]铺设芦苇沙障降低了近地表风速,有效拦截了风沙流,达到了防风固沙目的,是沙区光伏电站有效的防护措施。
英文摘要	[Objective]The benefits of a reed-sand barrier in a photovoltaic plant with regard to wind velocity, transported sand volume,and transported sand diameter were studied in order to provide a theoretical basis for the prevention and control of sand damage caused to the 200MWp photovoltaic plant in Hobq Desert, Northern China.[Methods]The wind speed after placing reed-sand barrier(20,50,100,200,310cm)and sediment transport(at a height of 030cm)near the surface of the photovoltaic plant were measured. Then,the trend of indicators such as the wind speed profile,surface roughness,friction speed,average jump height,wind prevention,and sand fixation benefit were analyzed.[Results]① The wind speed profile of the reed-sand barrier followed a logarithmic increase function and the goodness of fit(R~2)of the regression was >0.99.The aerodynamic roughness and shear velocity above the reed-sand barrier were 3.473.79times and 1.391.54times higher,respectively,than those above bare sand.The wind break function at a height of 20cm was the maximum (21.72%).② The total sediment transport of the reed-sand barrier was only 6.95%of that of the bare sand,and the sand-fixing benefit was 93.05%.More than 90%of the total sand transport flux above the bare sand was distributed within a height of 08cm,whereas only 51.39%of the total sand transport flux above the reed-sand barrier was distributed at this height.Therefore,the sand flux above the reed-sand barrier tended to move towards the high layer.[Conclusion]The reed-sand barrier acted as an effective windbreak and provided sand fixation by reducing the near-surface wind speed and intercepting sand transport.Thus,the reed-sand barrier is an effective protective measure for photovoltaic tracks in sandy areas.
