摘要: 辽南地下水类型多样,在开采量大的滨海低平原、岩溶发育带、构造切穿地段,地下水受海水污染严重.海水入侵过程可分为缓速、激速、慢速、停滞四个阶段.海水入侵方式与介质有关,呈脉状、面状、带状、复合等四种类型.

Abstract: Based on various patterns of groundwater and their abundance characters in south Liaodong Peninsula,the distribution,intrusion stage,intrusion pattern and intrusion characters of seawater intrusion in the serious seawater intrusion areas are analysed.The reasons to cause seawater intrusion are precipitation,recharge of surface water,artificial overpumping,lithology and geological structure.It can provide scientific basis for reasonable utilization of limited water resource in line with the local conditions.
