摘要
从大量的野外观测资料出发，总结龙口─莱州地区滨海含水层海水入侵的发展、演化规律；分折该地区海水入侵的基本特征与其水化学特征．研究区海水入侵的主要原因是过量开采地下水。地质因素对入侵地点、途径和方式起着一定的控制作用。海水入侵的发展由孤立的点开始，最终成为连续的面状入侵，其发展和强抽水中心密切有关、有两种类型的界面。过渡带地下水化学成分不是淡水和海水的简单混合，阳离子交换在其中起了重要作用。
Based on the field data, the developmental pattern of sea water intrusion in coastal aquifers in Logkou-Laizhou district is summarized, the basic characteristics of sea water intrusion and its hydrochemical characteristics in the study area are analyzed.The main cause of sea water intrusion in the study area is groundwater overpumping.Geological conditions play an important role in the localities, patterns and ways of sea water intrusion. Sea water intrusion expands from isolated spots to a large successive area, and its development is connected with the position of strong, intensive pumping centers. There are two types of salt water -fresh water interface. The chemical composition of groundwater in the transition zone is not a simple mixture of local fresh water and sea water, in which the canon-exchange played an important role.
