- Abstract:
-
The hydrochemical composition of the middle and lower reaches of the Yellow River in the wet season was investigated and the main control factors were discussed. The results show that the main hydrochemical coposition in Xiaolangdi reservoir area is HCO-3—Cl-—Na+, the total dissolved solids(TDS)and HCO-3 concentrations in the Xiaolangdi reservoir area are significantly higher in the bottom layer than those of the surface layer (p<0.05); the TDS, the concentrations of HCO-3, Ca2+ and Mg2+ are increasing from the upper reaches(the section of Fenglingdu)to the downstream(the section of Dongying)due to the downstream carbonate rock weathering. The Gibbs diagram, the anion-cation triangle diagram and the ion ratio map showed that the hydrochemical composition of the section of Fenglingdu to the section of Dongying is mainly affected by the dissolution of the evaporite salt rock and the weathering of the carbonate rock. Domestic sewage or industrial wastewater is also an important contribution to the hydrochemical composition. The results of principal component analysis show that the contribution rates of evaporation salt rock dissolution and carbonate rock weathering to hydrochemical composition are 46.55% and 35.90%, respectively.
