英文摘要	Lakes are important indicators of climate change. The change in lakewater level objectively reflects the availability of regionalwater resources. Analyzing the changes in water level and climate response of major lakes in countries along the "Belt and Road" is essential for sustainable water use and ecological protection. Based on the water level datasets of 39 large lakes (>400 km(2)) in China, Mongolia, and Russia (CMR) from 2002 to 2016, this study analyzed the spatiotemporal characteristics of water levels in major lakes of CMR, and their responses to climatic factors containing temperature, precipitation, and evapotranspiration. The results showed that (1) the water level of main lakes in CMR slightly increased with change rates ranged from -0.36 to 0.48 m/a, and the trends varied in lakes, (2) thewater level of most lakes was sensitive to temperature with sensitivity value ranged from -2.14 m/degrees C to 5.59 m/degrees C, (3) changes of annual cumulative precipitation and evapotranspiration contributed most to the change of lake water level, but key factors affecting water level varied in lakes. Human activity is an important driving factor for the change in water levels and its impacts need further study.
