摘　　要：地下水是十分宝贵的水资源,而过度开采地下水引起的地下水咸化已成为一个世界性环境问题。水文地球化学和环境同位素等分析方法已经广泛应用于此类问题的研究。地下水咸化成因有很多,不同地区的咸化过程也不尽相同,其中沿海地区由海水入侵引起的地下水咸化问题得到广泛关注。总结了沿海地区地下水咸化的研究进展,在了解地下水咸化过程中主要的水文地球化学作用的基础上,梳理了水文地球化学和环境同位素方法在研究地下水咸化成因与演化等方面的研究成果,并展望了水文地球化学和环境同位素方法在地下水咸化问题中的应用前景,认为该方法可以为地下水盐分来源和咸化特征研究提供重要支撑。Groundwater resources are very precious for us,but due to the over-exploitation the groundwater saliniation has been raised,which becomes a global environmental problem.The present study concerns the different salinization incentive caused by geologic setting.The salinization of groundwater in coastal regions mainly controlled by seawater intrusion has been most extensively studied.This paper mainly reviews the studies on groundwater salinization in coastal areas.Based on the studies of the mainly hydrogeochemical processes during the groundwater salinization process,the paper summarizes the progresses and achievements of the researches,focusing on the fields of the origin and evolution of salted groundwater,and also discusses the research methods of hydrogeochemistry and environmental isotope used in the problem of groundwater salinization.It is indicated that hydrogeochemistry and environmental isotope provide important support for the study of groundwater salinization.
