摘要: 对冀东地区咸水体的野外调查发现,当前该地区咸淡水界线和1980年相比发生了不同程度的偏移,最大变化量达6.35 km;同时发现咸淡水界线附近咸水、微咸水的开发利用是影响咸淡水界线变化的外界因素,含水介质条件是影响咸淡水界线变化的内在因素.通过对区域水文地质条件的综合分析,笔者把咸淡水界线的改变划分成初始、中间和最终三个阶段.Abstract: The fresh water-salt water boundary have different degrees of migration compared with 1980 in the eastern area of Hebei Province.The biggest change is about 6.35 km.The development and utilization of salt water and brackish water is the external fac-tors of the fresh water-salt water boundary changes.Aqueous medium conditions is the internal factors of the fresh water-salt water boundary changes.The changes of the fresh water-salt water boundary is divided into initial,intermediate and final stages,through a comprehensive analysis of the regional hydrogeological conditions.
