Brought forward and reasoned the forming mechanism of Maowusu sandy land. Based on the analysis of the development of Holocene rivers and related loess and windsandy geomorphology, the paper put forward the forming mechanism of Maowusu sandy land as follows: while the climate became dry, the exterior channels extended backwardly and cut through the remained lake system of ancient Hetao lake. This resulted in the rapid discharge of underground water. The vegetation living on this water resource was destroyed completely. Then the sand began to form.
