对海岛潜水流动特性和防止海水入侵污染问题的探讨

对小海岛地下潜水而形状、渗出高度以及盐水楔形状、长度的计算问题进行了探讨．认为控制地下水开采量，采取人工回灌井以及建造人工截水墙等工程措施保护地下潜水资源，防止地下水受海水入侵污染是有效的．

Research On Flowing Character of Phreatic Water and the Prevention of Pollution after Seawater Intrusion into Sea Island

The problems of water supply or small sea island,phreatic water depression curve,height of seepage face,and the form or saltwater wedge are considered in this paper.For the prevention of pollution after intrution or the seawater into the fresh groudwater,pumping well rate in a phreatic aquifer must be limited and sometimes injection well or impervious wall may be considered to build.These effective measures can protect phreatic water source from the pollution of saline water for seagirt sea island.
