摘要：In this paper, 50 sets of groundwater samples were collected in Jinan spring catchment, and SPSS was used for factor analysis, as well as piper diagram and ion ratio method for comprehensive analysis. The hydrochemical characteristics and influencing factors of spring water in Jinan spring catchment were studied. The analysis results show that the hydrochemistry type of the spring area is mainly HCO3-Ca or HCO3 SO4-Ca and the groundwater in the spring area is mainly affected by the weathering of rock minerals such as carbonate rock, halite and sulphate rock, and the influence of human activities should not be ignored. It is of great significance to clarify the cause of hydrochemistry in Jinan spring and to protect the spring environment.
