| Abstract: | his paper, according to the feature of e nvironment hydrogeology in Shijiazhuang city,Shows the regional trend and.local anomaly of groundwater hardness in this research area by trend surface analysis; and together considering the regression analysis between hardness and several other routine components, carries out a more comprehensive discussion on the formation causes of the four main hardness anomaly zones within this area. Finally, the author preliminarily puts forward the Ca2+, Mg2+ sources,chemical mechanism and main induced factor of the increase of groundwater hardness in Shijiazhuang city. |
