北长山岛海水入侵成因机理及现状评价

受全球气候变化影响,海水入侵已成为海岛地区普遍面临的地质灾害,严重制约海岛的开发与利用。本文以北长山岛为例,通过对不同含水层野外现场取样分析与高密度电法测试,探讨该地区海水入侵的成因机制与主要影响因素,并结合前人研究成果对该地区海水入侵现状进行评估。研究成果可为防治海水入侵灾害以及北长山岛地下水资源开发和管理提供科学依据。

Mechanism and assessment of seawater intrusion in the Northern Changshan Island

Saltwater intrusion has become a major hazard in the context of global change,which greatly affects coastal development.By field water sampling and high-resolution resistivity measurement,we attempted to detect the mechanism of seawater intrusion in the Northern Changshan Island.According to the results and compared with previous studies in the Northern Changshan Island,we assess seawater intrusion in this area and claim the potential of our study for seawater intrusion and groundwater management.
