摘　　要：本文以丰富的实际资料，论证了地下水的卤素元素（F、Cl、Br、I）的形成、含量及其分布规律与含水介质成分、上覆岩土性质、地下水退流条件、氧化还原环境、地下水矿化度之间的关系。根据江汉平原东部区和鄱阳湖区地下水中Br、I元素的调查研究结果及它们形成的控制因素与分布规律，结合长江三角洲南部区水文地球化学环境条件分析对比，指出该区是一个形成Br、I矿泉水的有利地区。With plentiful and real materials, this paper demonstrated the relations between the formation, content and distribution law of halogen elements (F, Cl, Br and Ⅰ) in ground water, and the composition of the aqiferous meson in ground water, quality of the overlying rock and soil,the condition of the run-off, environment of the oxidation and reduction and mineralized degree of ground water.The formation, migration and enrichment of F are mainly controled by the aquiferous medium and the quality of supertratum. The contents of Cl reduce in pace with growth of the runoff speed in ground water and incvease in pace with growth of mineralzed degree. The contents of Br increase in pace with growth of soilulmin, the contents of Cl and strengthening of the condition of reduction, but reduce in pace with growth of run-off speed. The contents of Ⅰ increase in pace with growth of the contents o soil-ulmin in medium and the condition of reduction, but reduce in pace with growth of the run-off speed.
