中文摘要	为探究沙区光伏阵列防风阻沙效应,以库布齐沙漠200 MWp光伏电站为研究对象,分别在阵列内上风向边缘(观测点A) 、下风向边缘(观测点B)和阵列外的上风向流动沙地(CK)设置观测点,通过HOBO小型移动气象站和阶梯式集沙仪测定风速变化和输沙情况。结果表明: ①观测点A和观测点B的粗糙度较流动沙地增大,各观测高度平均风速降低,0.2 m高度处风速降低值最大(27.76%、29.83%),随高度增加风速降低值减小,且相应高度处风速降低值均表现为观测点A<观测点B。②观测点A和观测点B输沙率为流动沙地(2.72 g·min~(-1)·cm~(-1))的65.07%和47.79%。因此,光伏阵列的存在对风速和输沙有显著的拦截作用,削弱了近地表风沙活动。研究结果可为评估沙漠地区建设规模化光伏电站对风沙环境的影响提供数据支撑。
英文摘要	In order to explore wind and sand resistance effect of photovoltaic array in sand region,this paper took the 200 MWp photovoltaic power station in Kubuqi dessert as research object,setting observation point A at the upwind edge in the array,observation point B at downwind edge and CK at upwind flows the sand outside array,and the variation of wind speed and sediment transport were measured concurrently through HOBO small mobile weather station and stepped sand collector. The results showed that: ① The roughness of observation point A and B had been increased than the shifting sandy land,and the average wind speed of each observed altitude decreased. At 0.2 m height,the wind speed had the largest reduction value (27.76%,29.83%),and the wind speed reduction value decreased with the increase of height,and the corresponding height wind speed reduction values were shown as observation point A < observation point B. ②The sand transport rate of observation point A and observation point B were 65.07% and 47.79% of the shifting sandy land (2.72 g·min~(-1)·cm~(-1)). Therefore,the existence of photovoltaic array had a significant interception effect on wind speed and sand transport,which weakened the near-surface sand activities. The research results could provide data support for the assessment of the impact of large-scale photovoltaic power stations on sand environment in desert areas.
