摘　　要：地下水氟含量高易引发地氟病。分析济南市先行区66件浅层地下水样品氟水文地球化学特征认为,研究区高氟水成因属溶滤-蒸发浓缩型。细的颗粒级配、较高的地下水水位、较高的包气带含氟量等地质条件,在强烈的蒸发气候条件下,蒸发浓缩作用、溶滤作用、离子交换作用共同作用,导致研究区出现高氟水区域。源汇理论分析认为,黄河水灌溉导致氟持续性输入研究区,在蒸发浓缩作用下浅层地下水中氟不断地富集,高氟水区域无论是河间洼地还是古河道,均为源汇项中的汇,表现为地下水位浅,且多伴随土壤盐渍化。High groundwater fluorine content will cause endemic fluorosis easily.After analyzed 66 shallow groundwater samples hydrogeochemical features from the Jinan Pioneer Area have considered that the area’s high fluorine water genesis belongs to lixiviating-evaporating concentration type.Fine grain size distribution,higher groundwater level,higher aeration zone fluorine content etc geological conditions,under strong evaporation climate,the combined evaporative concentration,lixiviation and ion exchange have caused high fluorine water zone appeared in the area.The source-sink theory analysis has considered that long-term Yellow River irrigation continuous fluorine input into the area,under evaporating concentration,shallow groundwater fluorine continuously enriched,high fluorine water zone whether it is in the interchannel depressions or in the paleochannels all the sinks in the source-sink term showing shallow groundwater level,and mostly accompanied by soil salinization.
