- Abstract:
-
In order to calculate the sediment load entering the Yellow River in the Ulanbuh Desert coastal more reasonably and accurately, and ascertain its impact on vegetation along the Yellow River, we made the sand dunes in the Ulanbuh Desert as the research objects. Through the methods of field topography survey, sand dune morphology measurement and remote sensing interpretation, we studied the morphological characteristics and transport characteristics of the dunes. The results show that the dunes mainly in barchans and barchans chain, which is in the direction of the southwest to northeast, the profile morphology of dune is asymmetric, and the leeward slope is obvious. In the process of development, the sand dune is influenced significantly by the southwest wind and the northwest wind. During the 5 years, the dunes moved the 19.45 m towards the river, and the movement of sand dunes has the characteristics of unidirectional rapid migration. The measures should be taken to curb the constant movement of sand dunes to the Yellow River.
