Distinguishing climate-and human-driven water storage anomalies in the Yellow River Basin
摘要
Abstract
Clarifying the impacts of climate change and human activities on water storage changes in a basin is es-sential for effective water resource management and protection.Using a statistical model,we reconstructed cli-mate-driven water storage anomalies(CWSA)from precipitation and temperature data at a 0.25°grid scale in the Yellow River Basin,China and isolated human-driven water storage anomalies(HWSA)from terrestrial water storage anomalies(TWSA)derived from GRACE satellite data.The results reveal the following trends:(1)CWSA in the Yellow River Basin shows a significant upward trend,with an average increase of 3.6 mm·a-1,mainly due to increased rainfall.(2)HWSA in the basin shows a significant downward trend,with an average decrease of 8.9 mm·a-1,with higher decreases in the middle and lower reaches,likely driven by excessive ground-water extraction.(3)Correlation analysis indicates that TWSA in the upper Yellow River is primarily influenced by CWSA,while in the middle and lower reaches,it is mainly influenced by HWSA.This study separately quanti-fies the effects of climate change and human activities on water storage changes in the Yellow River Basin.关键词
