【 摘 要 】

Dust is an important part of the particulate matter in the desert atmosphere environment . It moves to the nearby solar panels by suspension and saltation, which affects solar power. Collecting sand dust with sand sampler and compare with the dust distribution characteristics and parameters on the earth's surface to find out the transport law of dust and variation of dust weight with height in sand sampler. The results showed that the distribution of dust particle size obeyed the exponential distribution law. The dust particle size of surface dust is larger than that of sand sampler and the dust is in poor sorting which was caused by the selection of external factors such as wind. There is a good correlation between the dust in the sand sampler and the specific gravity of dust particle size in the earth's surface. The dust weight increases with height in sand sampler obey the law of power-decreasing. The heigher the solar panel, the surface dust deposition has less influence on it. The results will provide a theoretical basis for the impact of desert dust on solar power station.
