| 摘 要： | 采用GRACE卫星数据反演2002~2017年间华北平原地下水储量变化,并对该地区地下水储量变化进行时间序列分析,获取长期变化趋势.结果表明:华北地区地下水储量变化整体均呈现出下降的趋势,下降幅度最大的地方为黄河中下游地区,且山东中部和河南北部表现为加速下降的趋势,而京津冀地区的地下水储量的下降趋势得到了明显的减缓.

| Abstract: | In order to study the groundwater loss in north China plain,the groundwater storage change in north China plain during 2002-2017 was inverted by using GRACE(Gravity recovey and climate explorer)data in this paper.And its long-term trend change was obtained by time-series analysis.The results show that the groundwater storage change shows a falling trend in north China plain with the largest decline areas being the middle and lower reaches of the Yellow River.There is an accelerating downward trend in the central of Shandong and the north of Henan,while the decline trend has significantly slowed down in the Beijing-Tianjin-Hebei region. |
