基于GRACE的柴达木盆地水储量变化
The variation of terrestrial water storage in the Qaidam Basin based on GRACE data
摘要
Abstract
The terrestrial water storage(TWS)is an important indicator of regional water resources changes and water balance. The Gravity Recovery and Climate Experiment(GRACE)offers the data for research of variation in large-scale TWS.In this paper,we used the data of GRACE RL05 and the in-situ dataset to discover the spatial and temporal variation of TWS and its causes during 2003-2015 in the Qaidam Basin.The results showed that the variation of TWS showed an upward trend,with an ascending velocity of about 0.26 mm per month.The multi-year average increment of TWS gradually declined from the south to the north,and it ranged between 8.29-69.38 mm.The rise of TWS was consistent with the ascending trend of precipitation in the study area.The method based on GRACE data to calculate TWS can provide an important support for the assessment of TWS variation in data-scarce region in the northwest of China.关键词
