Introduction to Yangchu River: A Lifeline of Tibetan Nomadic Culture
The Yangchu River (羊曲), also known as “Yangmu Yong” (羊木涌), meaning “Stone Slab River,” is a crucial waterway originating in Dingqing County (སྟེང་ཆེན་རྫོང), Tibet. Flowing northward into Qinghai Province, this river serves as an essential natural resource, supporting the local ecosystem, Tibetan nomadic culture, and traditional herding practices.
The Yangmu Yong River is a tributary on the right bank of the Jiqu section in the upper reaches of the Angqu River. It is located in the northeastern part of the Tibet Autonomous Region and the southeastern part of Qinghai Province, China.
The river originates in the northern part of Gata Township, Dingqing County, Chamdo Prefecture, Tibet Autonomous Region. From its source, it flows northeast for over 20 kilometers before turning northwest. Upon reaching Muta Township, it resumes a northeastward course, flowing along the Tibet-Qinghai border for about 10 kilometers before entering the territory of Zadoi County in Yushu Tibetan Autonomous Prefecture, Qinghai Province. Finally, it merges into the Jiqu River northeast of Xinyun Village in Sulu Township, Zadoi County.
