| Abstract: | The spatial and temporal variations of hydrochemical characteristics were investigated by the mathematical statistics and Piper diagram methods based on the shallow groundwater quality monitoring data in Nankou,Beijing.The results showed that the hydrochemical type is relatively simple and the water is mainly of the HCO3-Ca·Mg type.The temporal and spatial variations of hydrochemical type are hardly affected by seasonal fluctuation.The variation tendency of the major ions in shallow groundwater is almost the same.The ions with the maximal concentration variation range are potassium and sulfate during both drought and flood seasons.The pH values and the concentrations of Ca2+,Mg2+and HCO-3are related to the groundwater flow.The chemical constituents of the supply source,the hydrodynamic field changes and the pollutant emission affect the hydrochemical characteristics of the shallow groundwater. |
