Abstract

Based on topographic maps in the 1970s and Landsat TM/ETM+ remote sensing images in the 1990s and the period from 2000 to 2011, the data of 83 lakes with an area above 10 km2 each in the Hoh Xil region, located in the hinterland of the Tibetan Plateau, were obtained by digitization method and artificial visual interpretation technology, and the causes for lake variations were also analyzed. It is highlighted that from the 1970s to 2011, the lakes in the Hoh Xil region firstly shrank and then expanded. The increase in precipitation was the dominant factor resulting in the expansion of lakes in the Hoh Xil region. The secondary factor was the increase in meltwater from glaciers and frozen soil due to climate warming
