摘要
为评估沙区光伏电站建设对风沙输移特征及生态环境的影响,利用2023年9月1日—2024年3月31日气象、沙尘强化观测试验期间风速等资料,基于Owen起沙估算模型,定量给出研究区光伏外围流沙区、光伏边缘区板间、光伏边缘区板下水平输沙通量。结果表明:(1)光伏外围流沙区平均风速显著高于光伏中心区和光伏边缘区,光伏外围流沙区约是光伏中心区和光伏边缘区的1.3倍和1.8倍;(2)光伏外围流沙区、光伏边缘区板间、光伏边缘区板下摩擦速度(u*)和起沙风速(ut)分别为0.36、0.28、0.30 m/s和6.0、4.3、4.6 m/s;(3)光伏外围流沙区、光伏边缘区板间、光伏边缘区板下平均沙尘水平通量分别为0.12、0.05、0.04 kg·m^(-1)·min^(-1)。沙区光伏电站建设对风速和水平输沙通量有显著的拦截作用,可有效减弱近地表风沙活动。
To evaluate the impact of photovoltaic power station construction in sandy areas on wind and sand transport characteristics and the ecological environment,meteorological data,including wind speed,collected during the intensive observation experiment on sand and dust from September 1,2023,to March 31,2024,were used.Based on the Owen sand emission estimation model,this study quantitatively calculates the horizontal sand transport flux in the surrounding quicksand area,the inter-panel area,and the under-panel area at the edge of the photovoltaic facilities in the study area.The results show that:(1)The average wind speed in the peripheral quicksand area of the photovoltaic facility is significantly higher than in the central and edge areas,being approximately 1.3 times and 1.8 times greater,respectively.(2)The friction velocity and sand emission velocity in the peripheral quicksand area,inter-panel area,and under-panel area of the photovoltaic edge are 0.36 m/s,0.28 m/s,0.30 m/s and 6.0 m/s,4.3 m/s,and 4.6 m/s,respectively.(3)The average horizontal sand transport fluxes in the peripheral quicksand area,inter-panel area,and under-panel area of the photovoltaic edge are 0.12,0.05,and 0.04 kg·m^(-1)·min^(-1),respectively.Overall,the construction of photovoltaic facilities in sandy areas has a significant impact on reducing wind speed and horizontal sand transport flux,effectively decreasing near-surface aeolian activity.
