- Abstract:
-
The Geochemical characteristics of groundwater in Yanqi Basin, Xinjiang, were studied based on correlation analysis and principal component analysis. Results of this study indicated that groundwater salinity increased from 0.21 g/L to 37.45 g/L from the upper reaches of Kaidu River to the irrigation area in the middle of the basin, and hydrochemical types of groundwater gradually changed from HCO3 type, HCO3-SO4 type, SO4-Cl type to Cl-SO4 type; cations were mainly Mg2+ and Ca2+ while anions were mainly SO42- and Cl- in the study area; groundwater salinity, EC, Mg2+, Ca2+, SO42- and Cl- presented strongly spatial variation while pH demonstrated very slightly spatial variation; groundwater salinity of the grassland was the maximum while groundwater salinity of Gobi was the minimum. The abundance of salinity and main ion contents of groundwater for different land use types decreased in the order:grassland > farmland > forest land > Gobi. Groundwater salinity has the significant positive correlation with the concentrations of Mg2+, Ca2+, SO42-, Cl- and HCO3-.
