滹沱河流域是华北平原浅层地下水超采的典型区域,本文通过整理分析区域内布控的地下水位监测点长系列实际观测数据,对浅层地下水时空规律进行了精细研究,系统总结了50多年来浅层地下水在各个时段的变化和分布状况,并进一步提供不同埋深段的分布面积及随时间的变化状况。在查明浅层地下水埋深的时空演变规律的基础上,揭示了目前研究区浅层地下水埋深整体大幅度下降的区域特征和从西部山前、北部河道带和东部向西南方逐渐增加的分布特征,警示了研究区当前面临的浅层地下水日益衰竭的紧迫现状。
The Hutuo River Basin is a typical area of shallow groundwater over-exploitation in the North China Plain. In this paper, the long-series observation data of groundwater level monitoring points distributed in the area are analyzed to study the temporal and spatial laws of groundwater in detail. Over 50 years Shallow groundwater changes and distribution in various time periods, and further provide the different depths of the distribution area and the changing conditions over time. On the basis of ascertaining the temporal and spatial evolution of shallow groundwater depth, the regional characteristics of the overall shallow groundwater depth reduction in the present study area are revealed. The regional characteristics of the shallow groundwater depth in the study area are gradually increasing from the southwestern part of the western piedmont belt to the east, Distribution characteristics, warning the study area currently facing the increasingly depleted shallow groundwater current situation.
