摘　　要：本文通过对辽东湾北部和东、西两侧滨海地区108个地下水井的监测数据进行分析,得出:(1)辽东湾海水入侵严重地区主要分布在辽东湾北部淤泥质海岸,其分布特点是严重海水入侵区、轻度海水入侵区由岸向陆呈带状分布;东西两侧以砂砾质海岸为主,局部地区海水入侵较重,大部分地区海水入侵较轻;(2)辽东湾地下水化学类型可分为五种类型,其分布特点是由岸向陆呈带状分布,规律明显,反映了海水入侵分布特征。氯化物型一般分布在微咸水至咸水区,重碳酸盐氯化物型或氯化物重碳酸盐型、重碳酸盐氯化物硫酸盐型或氯化物重碳酸盐硫酸盐型分布在微咸水向淡水过渡区,硫酸盐重碳酸盐型或重碳酸盐硫酸盐型、重碳酸盐型主要分布在淡水区。Based on the monitoring data of 108 groundwater wells in the north and east and west of Liaodong Bay, this paper comes to the conclusion：（1） The severe seawater invasion areas of Liaodong Bay mainly distribute in the north of Liaodong Bay. It shows a belt type of the severe seawater invasion areas and light degree seawater invasion areas from shore to land, but in the east and west of Liaodong Bay, the seawater invasion is severe, while most part of this area is lightly polluted;（2） The groundwater hydro￣chemical type is divided into 5 kinds. It shows a belt type from shore to land and the disciplinarian of the type change reflects distribution features of seawater invasion obviously. Chloride type generally distribute in brackish to saline water area, bicarbonate￣chloride type or chloride￣bicarbonate type and bicarbonate￣chloride￣sulfate type or chloride￣bicarbonate￣sulfate type distribute in brackish to freshwater transition zone, bicarbonate￣sulfate type or sulfate￣bicarbonate–type and bicarbonate type are mainly in freshwater area.
