Abstract：The F-concentration of deep groundwater in some areas of Cangzhou has seriously exceeded the standard,and the high fluoride area is also expanding.In order to understand the F-diffusion process,it is necessary to analyze the F-vertical migration state and the influencing factors.The vertical solute transport model of deep groundwater in Cangzhou was established by using MODFLOW,the high fluorine in aquifer Ⅲ comes from the higher concentration of fluorine in aquifer Ⅳ by vertical migration,the relationship between the influencing factors and the vertical migration of solute was analyzed by using the sensitivity coefficient formula.The solute transport state shows that the concentration will reached 1.64 mg/L at 2030.The main controlling factors of vertical migration of fluoride in groundwater is the fluorine concentration in the aquifer Ⅳ,and the followed is the effect of pumping amount.
