黄淮海地区2003-2014年GRACE水储量时空变化
Temporal and spatial variation of water storage in Huang-Huai-Hai area during 2003-2014 based on GRACE satellite data
摘要
Abstract
We obtained the variation of water storage in Huang-Huai-Hai area from 2003 to 2014 by using the monthly gravityfield data from GRACE satellite data .Then we compared it with the precipitation data in the same period to analyze its interan -nual and annual temporal and spatial variation characteristics .The results indicated that :temporally ,the water storage in theHuang-Huai-Hai area decreased by 0. 42 mm/month in 2003-2014 ,and that in Haihe and Huaihe river sub-basins decreased by0. 52 mm/month and 0.28 mm/month respectively .Within a year ,the water storage was in surplus only in February ,Septemberand December ,reaching the maximum in September to 9.86 mm ;the maximum water deficit occurred in June at 56.65 mm .Spatially,the water storage decreased from south to north .The water deficit in Haihe river basin was more serious than that inHuaihe river basin .But as the season changes ,the water deficit was relieved from south to north ,and switched to surplus inwinter .The spatial variation of water storage was mainly affected by precipitation ,and also affected by regional agricultural layoutand crop irrigation .GRACE data can facilitate the study of water storage variation in the Huang-Huai-Hai area and can pro-vide basis for the scientific management and planning of regional water resources .关键词
