寿光市高氟地下水的分布规律和成因

寿光市曾经是山东省地氟病防治的重点地区，通过在病区开展野外调查和岩土、水样测试等工作，总结了该区地氟病分布及地球化学环境特征，探讨了地氟病与地层岩性、土壤、地形地貌、浅层地下水、生活用水等的关系。在系统环境地球化学调查的基础上，研究了当地高氟地下水的成因，认为岩石、土壤、海水是高氟浅层地下水的主要来源，高氟浅层地下水形成可能有海侵富集型和蒸发浓缩型。分析了地下水中氟富集的因素与过程，提出了地氟病的防治措施。

DISTRIBUTION REGULARITY AND GENESIS OF HIGH-FLUORINE UNDERGROUND WATER IN SHOUGUANG CITY

Shouguang was once the key area of preventing endemic fluorine disease in Shandong Province.Based on field survey and soil and water sample test,this paper summarizes the distribution of fluorine disease area and geochemical environment characteristics and studies the relationship between fluorine disease and geochemical environments such as lithologic character,soil,terrain,shallow groundwater and water for human living.On the basis of systematic environment geochemical survey,the cause of high-fluorine groundwater was studied.It is considered that rock,soil and seawater constitute the main sources of high-fluorine groundwater.There probably exist two patterns for the formation of high-fluorine shallow groundwater,seawater invasion enrichment and evaporation concentration.The factors and processes of fluorine enrichment in groundwater are studied and the preventing measures are proposed.
