莱州湾地区海水入侵与地貌的关系

摘要:
于1993－1995年，通过野外实地考察，以及应用卫星影像解译、水文地质及第四纪地质钻孔资料分析等多种方法，综合研究莱州湾沿岸地区海水入侵与地貌关系。研究表明，莱州湾南岸与东岸地貌条件不同，海水入侵类型不同，南岸以古海水即成（卤）水入侵为主，东岸以现代海水入侵为主；海岸地貌以及滨海平原区古河道、古湖沼洼地是影响海水入侵的重要地貌因素；古河道带上，海水以层状入侵和越流入侵为主；平原洼地中，海水以垂向和侧向入渗为主。沙质海岸易于发生海水入侵，而基岩海岸一般尚无明显的海水入侵。

REALATIONSHIP BETWEEN THE SEAWATER INTRUSION AND LANDFORMS IN LAIZHOU BAY AREA

Abstract:
To study the relationship between seawater intrusion and landforms, field investigations, laboratory analyses, satellitic photos, drillings, and relief maps, were used in this May, 1993 to October, 1995 study on the relation between seawater intrusion and landforms. The results showed that sandy bays and argillaceous bays favor seawater intrusions. Because geomorphic types in Laizhou Bay's south coast are different from those in the east coast, seawater intrusions in the south coast were different from those in the east coast. Paleochannels and coastal landforms were the main geomorphic types that affected seawater intrusions. The modes and intensity of seawater intrusions were not alike in distinct landform units and types.
Key words:  Laizhou Bay, Seawater intrusions, Landforms
