Abstract On the basis of studying the geological conditions of convective geothermal resources on the East Bank of the Yellow River in Yinchuan， the hydrochemical characteristics of geothermal water in the study area are comprehensively analyzed by using the analysis data of geothermal water quality， and the quality of geothermal water is evaluated. The evaluation results show that the geothermal water in the study area has high salinity， strong corrosivity and is not easy to scale. It is a fluoride hot spring containing metasilicic acid and has certain medical and physiotherapy value.
