库布齐沙漠光伏设施对近地表风速和输沙通量的影响
Impact of the Photovoltaic Facilities in Kubuqi Desert on Near-Surface Wind Speed and Sand Transport Flux
摘要
Abstract
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.关键词
