摘要
莱洲湾南岸地下水在咸水入侵条件下发生了较大的变化,从山前冲洪积平原至海岸带共存在6种类型的地下水。本文对研究区地下水化学成分的区域分布进行了研究,并通过水文地球化学调查与室内试验,结合同位素测定资料与PHRQPITZ的模拟结果,对各种类型地下水的形成原因做了深入探讨。指出在咸、淡水过渡带发生了阳离子交换。此外还揭示出卤水形成过程中发生了石盐、泻利盐的溶解。
The composition of the groundwater has been changed in salt-water intrusion condition in the south coast area of the Laizhou Bay. Distribution of different groundwater type is presented in this paper. The genesis of every kind of groundwater is discussed on the base of hydrogeological and hydrogeochemical surveys, experiments in labs, data of isotopes and the modeling result by PHRQPITZ. Relative contents of ions show that 2 cation exchanges took place in the study area. One is Ca2+ in fresh water exchanging for Na+ absorbed in soils. This cation exchange was formed long before. The other is reverse which occurred in salt-water intrusion. Besides the solution of halite and epsomite during the evolution of brine is pointed out in the paper.
