Abstract The Wayue village belongs to the Chaya County,Changdu City,Tibet. Through remote sensing interpretation,we can intuitively observe its special river topography:“solitary mountain” and ring-shaped negative land. According to the survey,typical river deposits were found in the negative land. Identified as the palaeoriver channel landform. In addition,special river-lake confluence deposits were found at the mouth of the ancient channel,indicating that the river was blocked in history,providing clues to the cause of the river diversion,and inferring that the fluvial environments at that time were extremely turbulent,with several flooding periods. During the intermittent period,we speculates that it might have been related to the last glacial period. Combined with remote sensing interpretation and geological background,the river evolution model of the Wayue village of the Lancang River is finally summarized. Because Wayue village is located along the national Sichuan-Tibet Railway,engineering geology is of great significance. The research results presented in this article are of great significance for ensuring the smooth progress and safety of railway projects.
