Abstract: The Sanggan River originates from Ningwu county of Shanxi, flows over Datong—Yangyuan basin and Wangjiawan Mountains, and continues into Huaizhuo basin. The terraces are well developed in the Yangyuan—Zhuolu section of the Sanggan River, and it is helpful to understand the evolution of the Sanggan River and the neotectonic characteristics of the area. And it is significant for learning the evolution of the ancient Yangyuan lake and Zhuolu Lake to study the geomorphic evolution of Yangyuan—zhuolu section of the Sanggan River. Authors of this paper studied the terraces of YangYuan—zhuolu section of the Sanggan River comprehensively by field measurement, interpretation of remote sensing images and processing of high-resolution DEM data. The results show that the faults between mountain and basin activated intensely, and the area experienced block difference lifting movement. Under the influence of the differences of movement, the Sanggan River has experienced an evolution process that divided it into two rivers and eventually ran through again.

Key words: Geomorphic evolution, Sanggan River, River terrace
