2002-2020年海河流域陆地水储量变化的时空变化特征
Temporal and spatial variation characteristics of terrestrial water storage change in the Haihe River Basin from 2002 to 2020
摘要
Abstract
In order to explore the temporal and spatial variation of terrestrial water storage change in the Haihe River Basin,the terrestrial water storage change in the Haihe River Basin was calculated based on GRACE(Gravity Recovery and Climate Experiment)satellite and GRACE-FO satellite data from 2002 to 2020.The reliability of GRACE/GRACE-FO satellite data was explored through the correlation between valuation of changes in groundwater storage and groundwater level variation.The re-sults showed that:① The correlation between the valuation of changes in groundwater storage and groundwater level variation was strong,and the correlation coefficient was 0.78.② The terrestrial water storage change in Haihe River Basin showed a de-creasing trend from south to north;the annual change rate of terrestrial water storage change reserves is-9.80 mm/a.关键词
