Based on the systemic chemical analysis for the Fuyang River in Handan area,it is revealed that:(1) there mainly are five type waters as mainstream,karst,reservoir,coal mine drainage and city waste ones in this valley,among which the water types are HCO₃·SO₄-Na·Ca for mainstream,SO₄·HCO₃-Na·Ca for karst,HCO₃·SO₄-Mg·Ca for reservoir,HCO₃·SO₄-Na·Ca or CO₃·SO₄-Ca for coal mine drainage,and Cl·SO₄-Ca·Na or Cl-Na for city waste waters,while the total dissolved solids(TDS) are less than 1 g/L for the former three type waters and great than 1 g/L for the latter two ones;(2) there is a trend of salinization and acidification for the river with the notable increase of concentrations of Ca₂⁺,Mg₂⁺,Na⁺⁺K⁺,HCO₃-,SO₄₂-,Cl-and NH₄⁺,and TDS values in the mainstream water along the river pathway starting from the Dongwushi Reservoir,and the decrease of pH value;(3) the salinization,acidification,nitrogen pollution and local heavy metal pollution for this river are the main hydrochemical characteristic of the river influenced by artificial factors,and the most important mechanisms of such an influence are manufactural evaporation,direct importing chemicals and intensification of chemichal weathering through environmental change.
