The lakes on the high-altitude plateau play an essential role in the local water cycle. Alpine lakes on the Tibetan Plateau have experienced a rapid expansion since 1990s under the global climate change. In order to understand the changing pattern of alpine lakes on the Tibetan Plateau in recent years, this study monitored 127 lakes larger than 50 square kilometers annually on the endorheic Tibetan basin from 2009 to 2014. Based on a semi-automatic lake extraction method, we combined multi-temporal HJ-1A/1B imagery and Landsat imagery to extract lake boundaries accurately. The results have shown that the surface area of large lakes experienced a significant expansion with an overall rate of 231.89 km~2 yr~(-1) (0.87 %yr~(-1))and the trend of lake expansion is slowing down during the study period. 104 lakes expanded at a rate of 271.08 km~2 yr~(-1) (1.02 %yr~(-1)), while 23 lakes shrunk at a rate of -39.19 km~2 yr~(-1) (-0.15 %yr~(-1)). The spatial pattern of the lake area dynamics also have shown significant regional difference. The expanded lakes are distributed in the most of the east and north study area, while the stable lakes are mainly distributed in the south basin. Besides, the shrunken lakes are scattered at the border of the study area. Based on the comparison between the changing rates of glacier-fed and non-glacier-fed lakes, glacier-fed lakes have shown a much rapid expansion trend than non-glacier-fed lakes, which indicates that the increase of glacier wastage is one of the main factors that contributed to the expansion of Tibetan lakes.
