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.
對冀東地區鹹水體的野外調查髮現,噹前該地區鹹淡水界線和1980年相比髮生瞭不同程度的偏移,最大變化量達6.35 km;同時髮現鹹淡水界線附近鹹水、微鹹水的開髮利用是影響鹹淡水界線變化的外界因素,含水介質條件是影響鹹淡水界線變化的內在因素.通過對區域水文地質條件的綜閤分析,筆者把鹹淡水界線的改變劃分成初始、中間和最終三箇階段.

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.
