典型地质环境下的高氟地下水形成影响因素分析——以山东省高密市为例

高密市是山东省地氟病防治的重点地区,该区地下水中氟含量之高、地氟病分布之广,危害程度之严重均居山东省之最。高密市典型的地形地貌、气候条件、地质条件以及水文地质条件是造成该区地氟病高发的主要原因。本文分析了高密市与高氟地下水相关的地质环境,通过大量水样岩土样品的分析测试,半定量阐述了地下水中F元素的富集与地形地貌、地质岩性、气候条件、水动力条件的相关关系,总结出高密市典型地质环境下高氟地下水形成的影响因素。以期对高氟地下水形成机制的研究工作提供借鉴,以及对高氟区寻找低氟地下水提供参考。

Analysis on the influence of forming factors of high fluorine contained groundwater in typical geological environment A case from Gaomi area

Gaomi is an important controlling city of the endemic fluorosis. The Fluorine content in groundwater is the highest in Shandong Province. The topography and geomorphology, climate, geological and the hydrogeological conditions are the main causes of the endemic fluorosis. The paper analyses the analyzes the geological environment related to the high fluorine groundwater, semi-quantitatively presents the relationship between the enrichment of fluorine in groundwater and the topography, geomorphology, geologic lithology, climate, and hydrodynamic conditions based on the massive test results of water and soil samples, concludes the influence factors forming high fluorine groundwater in typical geological environment. The paper provides a reference for the study on the high fluorine groundwater formation mechanism and the water resource exploration in high fluorine areas.
