In this study, the water balance method PER combined with the land surface model Variable Infiltration Capacity (VIC) was used to estimate the terrestrial water storage (TWS) in Yangtze River basin during 1982-2005, and its future changes during 2071-2100 under climate change scenarios A2 and B2.The estimated TWS during 1982-2005 and those during 2071-2100 under scenarios A2 and B2 have similar seasonal amplitude of 60-70 mm, and the peaks of TWS appear in June while that under A2 appears two-peaks in response to the related precipitation pattern.It is also found that the recharge time of TWS is from February to June during 1982-2005, and from March to June during 2071-2100 under A2 and B2 scenarios.
