英文摘要	Lakes in arid and semi-arid regions are experiencing dramatic variations in water level and volume, which has caused severe ecological and social problems. Long-term study of the lake dynamics in arid/semi-arid regions could provide particular insights into the mechanisms driving lake variations, while hydro-meteorological data were usually limited in these regions, especially before the instrumental period. In the present study, we focused on a typical great lake - Hulun Lake in semi-arid region in northern China, simulated the hydrological processes from 1904 to 2016 using SWATmodel, CRUNCEP7 reanalysis data, and sparse records of lake level during 1900s1950s, and investigated the mechanisms driving the dramatic variations of the lake at the hundred-year time scale. Results illustrated that the simplified Penman equation by Valiantzas (2006) could reproduce the evaporation dynamics of Hulun Lake, with monthly R-2 being 0.93-0.95. The long-termsimulation since 1904 reproduced runoff dynamics, whichwere consistentwith the dramatic variations of lake level over hundred years. The largest water level increase (similar to 5.0min 1950s) and decrease (similar to 4.5min 2000s) during 1904-2016were jointly affected by river runoff, lake evaporation, and precipitation into the lake. Both the positive/negative phase and the multidecadal trend of PDO clearly influenced the hydrological cycle of Hunlun Lake, especially for the period of 1904-1950 with low lake levels. Overall, the present study provided a methodology for investigating the hundred-year hydrological processes for lakes in semi-arid regions in northeastern Asia. (C) 2021 Elsevier B.V.
