摘要: The gravity fields from the Gravity Recovery and Climate Experiment (GRACE) satellite have been used to estimate groundwater depletion in many parts of world. Groundwater assessment North China, however, is affected by large anthropogenic disturbance on mass variation. Using water survey data coal flow statistics, we show that variations China during 2003-2011 were largely reservoir regulation, diversion, transport. According our estimates, loss rate (-14 -8.4 mm yr-1) was offset gains caused regulation (1.3 yr-1), diversion (4.4 transport (1.9 Plain. We note impacts change must be taken into account when using GRACE area intensively altered human activities. 2013. American Geophysical Union. All Rights Reserved.
