Lop Nur
Summary
Lop Nur or Lop Nor (from a Mongolian name meaning "Lop Lake", where "Lop" is a toponym of unknown origin) is a former salt lake, now largely dried up, located in the eastern fringe of the Tarim Basin, between the Taklamakan and Kumtag deserts in the southeastern portion of the Xinjiang (Xinjiang Uygur Autonomous Region). Administratively, the lake is in Lop Nur town (), also known as Luozhong () of Ruoqiang County, which in its turn is part of the Bayingolin Mongol Autonomous Prefecture.
The lake system into which the Tarim River and Shule River empty is the last remnant of the historical post-glacial Tarim Lake, which once covered more than in the Tarim Basin. Lop Nur is hydrologically endorheic – it is landbound and there is no outlet. The lake measured in 1928, but has dried up due to construction of dams which blocked the flow of water feeding into the lake system, and only small seasonal lakes and marshes may form. The dried-up Lop Nur Basin is covered with a salt crust ranging from in thickness.
An area to the north west of Lop Nur has been used as a nuclear testing site, and since the discovery of potash at the site in the mid-1990s, it is also the location of a large-scale mining operation. There are some restricted areas under military management and cultural relics protection points in the region, which are not open to the public.
From around 1800 BC until the 9th century the lake supported a thriving Tocharian culture. Archaeologists have discovered the buried remains of settlements, as well as several of the Tarim mummies, along its ancient shoreline. Former water resources of the Tarim River and Lop Nur nurtured the kingdom of Loulan since the second century BC, an ancient civilisation along the Silk Road, which skirted the lake-filled basin. Loulan became a client state of the Chinese empire in 55 BC, renamed Shanshan. Faxian went by the Lop Desert on his way to the Indus valley (395–414), followed by later Chinese pilgrims. Marco Polo in his travels passed through the Lop Desert.
