【摘要】 海岸带海水入侵问题一直是国际社会共同关注的焦点。海水入侵的影响因素很多，其中人为因素占较大比重。海水入侵的方式因地而异，孔隙水含水层海水入侵较为严重。在研究中突变界面模型和过渡带模型各有其实用性。其中过渡带模型更具有适用价值，是今后主要的研究方向。本文概述了海岸带海水入侵问题现状，系统地总结了海岸带海水入侵模型近 40 多年来的研究成果，分析了研究中存在的困难，为进一步的研究打下基础。更多还原

【Abstract】 The seawater intrusion of coastal areas has been a focus of common concern in the world. The factors affecting seawater intrusion are quite a lot , of which the artificial one plays a chief part. The manner of seawater intrusion varies with local conditions. The more serious one is the seawater intrusion in porous aquifers. The abrupt interface model and the saltwater-freshwater transition zone model have their respective practicability in the study. Owing to its more applicable value, the latter will be a major research target. This paper summarizes the actuality of the seawater intrusion of coastal areas and the achievement of the study in the past 40 years, analyses the difficulties in research work, and thus provides a favorable foundation for further study.更多还原
