Abstract: This paper is designed to discuss the periglacio-geomorphic distribution and evolution in the source region of Urumqi River on the Tianshan Mountain on the basis of repeated mea-surements and investigation in the field during the period of from 1985 to 1989. The major conclusions arse as follows.
