摘要
在前人研究我国北方高氟水分布特征基础上,总结了我国北方三种高氟水的形成机制:①浓缩富集型;②岩石溶滤型;③海侵富集型。通过对三个典型地区——张掖盆地、赤峰盆地以及沧州平原的地貌地质条件、气候条件、含水层条件的系统分析以及水化学、同位素证据,得出三个地区的高氟水形成机理分别为蒸发浓缩富集、岩石溶滤以及海侵富集,并针对我国国情,提出了防止氟中毒的建议和方法。
Based on the achievements about distribution study of high-fluoride water of north China the paper,summarized three types of high-fluoride water forming mechanism:enrichment type,rock leach type and seawater intrusion type.Illustrating geological and geographical condition,climate condition,aquifer condition,and evidences of water chemistry and isotope of three typical areas,Zhangye Basin,Chifeng Plain,Cangzhou Plain,the paper draws the conclusion that the high-fluoride water forming mechanisms of the three typical area are evaporation concentration,rock leach type and seawater intrusion type.According to China's national conditions,the paper gives advice and measures to prevent fluoride poison.
