摘要
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 City. 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 chemical constituents of the supply source, the hydrodynamic field changes and the pollutant emission affect the hydrochemical characteristics of the shallow groundwater.
