The Lancang River originates from Qinghai Province of our country and flows through the outside to be renamed as the Mekong River. It is one of the most important international rivers in China and even in the world.Through the field investigation of the hydrology, geomorphology, glaciers and rivers in the source region of the Lancang River and using the global positioning system (GPS ), Geographic Information System (GIS) and Satellite Remote Sensing System (SRS) to determine the source of the Lancang River (Mekong) and its source.According to the length of the river, and with reference to catchment area, river water and other elements, the final The positive source of the Lancang River is Za’a Qu, which originated from Guozongmucha Mountain at an elevation of 5514m in Zhaqing Township, Zaduo, Zaduo, Yushu Tibetan Autonomous Prefecture, Qinghai Province, China The source of the Lancang River is a 0.67km2 glacier, At 5 2 2 4m. Its geographical location is 94 ° 41’44 “east longitude and 33 ° 42’31” north latitude.
