Received Date: 04 January 2012

摘要: 海(咸)水入侵倒灌是各沿海城市的主要地质灾害之一。青岛市位于黄海之滨,海岸线绵长,海水入侵主要发生在辖区内主要河流的入海口周围。主要原因是入侵区附近地下水开采量过量,引起海水、古海水或高矿化地下咸水沿含水层向陆地方向侵入,从而侵染了地下淡水资源。论述了灾害成因机理及严重危害性,并提出相应的防治措施。

Abstract: Sea (salt ) water intrusion is one of main geologic hazards in coastal Qingdao. It mostly occurs around main estuaries into the Jiaozhou Bay. Sea water and ancient seawater or high mineralized underground salt water intrude to the land along the aquifer due to over exploitation of groundwater around the intrusion zones. As the result, groundwater resources are contaminated. Based on the study of the formation mechanism of the disaster, prevention measures are proposed in this paper.
