图8 直流电测深反演电阻率不同标高切片推断咸淡水界线 (以电阻率5 Ω·m等值线为界线,小于5 Ω·m为咸化区,大于5 Ω·m为未咸化区)

Fig.8 Salty and fresh groundwater boundary line of different elevation was inferred by the DC inversion resistivity section (salty and fresh groundwater is demarcated by the resistivity of 5 Ω·m, less than 5 Ω·m was salt water area, greater than 5 Ω·m was fresh water area.)
