英文摘要Geochemical processes controlling hydrochemical evolution of shallow groundwater (<200 m) were studied in the Chahan Lake Basin, China. A combination of chemical and isotopic tracers (delta H-2, delta O-18,Sr-87/Sr-86,H-3 and(14)C), along with inverse geochemical modeling were applied. Shallow groundwater primarily originates from local precipitation, and has negligible mixture with deep groundwater. Shallow groundwater in the recharge areas and discharge areas were recharged during the Holocene and late Pleistocene, respectively. Groundwater chemistry systematically changes along the flow path from northwest to southeast: water type evolves from Ca.Mg-HCO3 type in the recharge areas through mixed cations-HCO3 type towards Na-HCO3 and Na-HCO3.SO4 type in the discharge areas. Carbonate dissolution and cation exchange are the predominant processes controlling groundwater chemical evolution, which principally occur in the recharge areas and discharge areas, respectively. Furthermore, human activities (e.g. agricultural fertilizer) also significantly affect the chemical compositions of groundwater in the recharge areas, particularly NO3- and Cl- contents. Silicate weathering is found to be an insignificant reaction, although the aquifer studied is composed of silicate-dominated sandstone.
