Abstract Underground brine resource is rich,has a high resource value and economic value,and can be used in military industry, chemical industry, electronics, pharmaceutical and other fields. For further development and utilization of brine resource, evaluation of development and utilization prospects, of the brine resource research into the cause, evolution and source information of the brine, the brine was discussed from the viewpoint of underground brine chemical characteristics. According to the sodium chloride coefficient,desulfurization coefficient,calcium magnesium coefficient, sodium and calcium coefficient, bromine chloride coefficient a and potassium chloride coefficient in groundwater, the genessis of the underground brine was analyzed and speculeted; according to the mole concentration ratio (Na + Ca)/and Cl compared with other water bodies to genetic types were determined analysized ; according to the mole concentration ratio cNa/cCl judging Na and Cl,the evaporation concentration and leaching effect of chlorine salt dissolving,formation were judged in order to brine determined the formation procecs of the brines; according to the ratio of the density of Cl and Br,the sediment source of the brine were determined.
