Danniang Sand Dune Valley and Sand Source AreaThe valley where Danniang Dune was located was featured by dense contours on both sides of the valley floor, steep valley slopes, large slopes, and relatively high heights. The contours near the valley where the sand dunes were located were sparse and extended to higher altitudes. The river course was more curved, the flow of the river was slower, and the accumulation of water was stronger. The sand dunes were formed by the accumulation of wind power, and the source of the sand was the flood plains and sandbars.
What are moving sand dunes and fixed sand dunesMoving sand dunes referred to sand dunes that were easily changed in position. There was little vegetation on the surface, and the sand dunes had a typical shape. They were easy to move along the wind under the influence of the wind. It poses a great threat to transportation and industrial and agricultural construction. The moving speed of a moving sand dune is related to the height of the sand dune, the wind speed and its variation rate, and the condition of the underlying surface. It was mainly distributed in China's Xinjiang, the Yellow Plateau, and the Inner Mongolia Plateau.
A fixed sand dune was a sand dune that had a relatively constant position. Most of the ground was covered by vegetation, covering more than 30%, causing the movement of sand to almost completely stop, and the position of the sand dune was relatively stable. The formation of fixed sand dunes was closely related to vegetation. The blocking effect of vegetation began to accumulate, and as the accumulation thickened, it grew taller, forming a multi-layered arc bedding structure. The fixed sand dunes had little effect on the sand movement.
According to the information provided, moving sand dunes and fixed sand dunes could be distinguished according to the following characteristics:
- Vegetation coverage: There is little vegetation on the surface of moving sand dunes, while most of the fixed sand dunes are covered by vegetation.
- Sand dune mobility: Moving sand dunes are easy to move with the wind, while fixed sand dunes are relatively stable and almost do not move.
- Sand dune shape: The moving sand dunes are typical, often in the shape of a crescent, while the fixed sand dunes are in the shape of multi-layered arc bedding structure.
In summary, there were obvious differences between moving sand dunes and fixed sand dunes in terms of vegetation coverage, sand dune mobility, and sand dune shape.
