Abstract:We analyze the temporal and spatial terrestrial water storage(TWS) changes in the Loess plateau from April 2002 to December 2016 using the COST-G GRACE temporal gravity field model, and data including precipitation, temperature, surface water(SW) of the GLDAS model, measured shallow groundwater(GW), NDVI. Then, we use the partial least squares regression method to qualitatively analyze the driving factors of TWS changes in the Loess plateau. The results show that: 1) During the study period, the TWS changes of the Loess plateau have the characteristics of rising-declining-declining gently, and the loss of TWS in Shanxi province is obvious. 2) From 2004 to 2009, the coal mining water, human domestic water, and vegetation effect are important factors for the loss of TWS in the Loess plateau. Industrial water, human domestic water and temperature rise are important factors for the decline of TWS in the Loess plateau from 2010 to 2016.
