Abstract The disappearance of the ancient Loulan city in Xinjiang has been regarded as a riddle. Through the application of satellite remote sensing technology and the interpretation of the distribution characteristics of the old river in Loulan area from TM image, the authors have found that there are two landslide sites and barrier lakes located in the upper reaches of the river. Based on this discovery, it is thought that the abandoning and final disappearance of Loulan might be attributed to landslides which cut off its water source and broke off its water supply.
