| Abstract: | In order to deeply study the formation mechanism of hydrochemical composition of groundwater in the inland plains,based on the analysis of 55 sets of groundwater samples and 7 sets of core sample parameters,mathematical statistics,ion scale coefficient method and numerical method were used to invert the water and salt transport of groundwater process.The results show that the concentration flux of groundwater cations in the cohesive soil in the study area always increased first and then decreased,presumably 50 min shallow groundwater,Na+might be enriched in aqueous media,and Ca2+in groundwater of 80-110 m might be enriched in aqueous media.The hydrochemical components of groundwater in the plain area have vertical zoning characteristics.The main hydrochemical type was Cl-Na type,TDS>5 g/L.Water-rock interactions such as dissolution and precipitation,decarbonation,and cation exchange that was the main reasons for the differences in the hydrochemical composition of groundwater at different depths.The research results provide a scientific basis for the utilization and protection of groundwater resources in inland plains. |
