Lakes are sensitive indicators of climate change, and studying their dynamics is important for revealing global climate change. This study selected the Hala Lake Basin in the northeastern Qinhai-Tibet Plateau as a study area, and examined the relationships between the temporal and spatial changes of lake in the Northeastern Qinghai-Tibet Plateau and the climate change based on remote sensing imagery, climatological data, and topographic data from 1986 to 2015. Results showed that the lake area change presented a "V"-shaped pattern in the Hala Lake Basin during the study period. The dynamic change process can be divided into two stages: The stage of volatility decline (1986-2001) and the stage of volatility rise (2001-2015). The lake area decreased from 593.68 km2 in 1986 to 584.83 km2 in 2015 (with a reduction of 8.85 km2) and increased from 584.83 km2 in 2001 to 614.31 km2 in 2015 (with an increase of 29.48 km2). Correlation analysis between changes in lake and glacial areas and climatic factors in the same period of remote sensing data shows that the change of lake area is positively correlated with the stage precipitation, and the relevant significance level is above 0.01. The dominant factor of the dynamic change of lake is precipitation.
