“㓜交movie在线观看”珠江委创新开展㓜交movie在线观看北部湾地区地下水数字监管

  中新㓜交movie在线观看网广州12月31日电 (㓜交movie在线观看记者 王坚)水利部珠江水利委员会(下称“珠江委”)31日通报称,本年度以北部湾地区重点区域作为研究范围,该委探索利用GRACE重力卫星数据反演地下水储量变化情况,结果表明,北部湾地区地下水储量年内受降水影响出现呈现明显季节性周期变化,在2018—2023年整体呈㓜交movie在线观看现逐步稳定到稳步上升的变化趋势。

  珠江委介绍,地下水是水资源的重要组成部分,为实时掌握地下水储量动态变化,完善地下水线上监管工作体系。本年度以北部湾地区重点区域作为研究范围,该委首次采用GRACE重力卫星数据,结合水量平衡方程、水文模型,反演探查2018—2023年北部湾地区地下水储量时空变化,通过对比地下水水位实测数据、地下水蓄变量,分析地下水储量演变趋势、影响因素及其响应关系。

  结果表明,北部湾地区地下水储量年内受降水影响出现呈现明显季节性周期变化,在2018—2023年整体呈现逐步稳定到稳步上升的变化趋势;其中地下水超采区等重点区域地下水储量上升速率明显,地下水超采综合治理成效显著。

  珠江委表示,该项工作推动了遥感技术在珠江流域地下水监管工作中落地应用,为实现地下水数字监管提供技术支撑,为南方平原区地下水动态监测预警、超采区治理成效评估提供了新路径。(完)
