The yellow river-bed evolution a statistical proof of the mountain-river-desert conjecture

Abstract

When the Yellow River flows through the Hetao Plain in Inner Mongolia, north China, it forms a mountain-river-desert system with the Yin Mountains on one side and the Hobq desert on the other side. In this mountain-river-desert system, a dense growth of green grass is formed in the area fronting the river and with the mountains at the back, however, on the opposite the river, the area has an inherent trend to lost moisture, which might cause desertification. This study verifies this theoretical conjecture by analyzing the Yellow Riverbed change from 2014 to 2021. The seven year change showed the river is the inherent boundary between the grassland and the dessert, and it was nothing to do with the river banks? past earth surfaces.
