中文摘要：

本文对河北平原深层高氟地下水进行了研究，发现地下水中的氟含量与锶同住素组成（^87Sr）在水文地球化学性质上有3个相似点和一个明显的差异：①wsr和F一有相同的矿物来源，例如黑云母、角闪石等，这可能是一个普遍的规律；（参河北平原深层地下水的^87Sr值和其中的F含量具有相似的分布规律，高值区都分布在子牙河附近及其以东的地区；（3）^87Sr／^86Sr比值（或^87Sr）与F-含量呈明显的正相关关系，都是水-岩作用“时间积累效应”的结果。二者的差异在于最大值的分布区不一致：δ^87Sr最大值分布区在子牙河一带，而F-含量最大值的分布区在吴桥-东光-沧州一带。本研究在一定程度上揭示了锶同位素对研究高氟地下水的形成机理、分布规律和生态效应的良好示踪作用。

英文摘要：

This paper studied deep groundwater of F- high content in Hebei Plain, and found that there are three similarities and a difference on relations between F- content and strontium isotopes composition, according to the study on Sr and F on geochemistry and hydrological geochemistry and ^87Sr /~^86Sr ratio of groundwater in Hebei Plain. （1）F- and ^87Sr have the same sources, such as biotite and hornblende, which may be a universal phenomena; （2）δ^87Sr value, and F- concentration have similar distribution that higher F- concentration （〉 1.0 m/L） and higher ^87Sr value are both in the vicinity of Ziya River and the eastern area; （3）^87Sr/ ^8Sr radio is positively correlated with F- content in groundwater, reflecting the result of ＂time-accumulation＂ of water- rock interreaction. However, the maximum distribution area is not consistent. The δ^87Sr maximum distributes around the Ziya River while the maximum distribution of F- is mainly in the region of Wuqiao-Dongguang-Cangzhou. The study revealed to a certain extent that strontium isotope plays a good tracer role to study the formation mechanism distribution and ecological effects of groundwater with high F- content.
