- Abstract:

Based on the results of water chemistry of six stations in Urumqi River Basin in different seasons of 2011—2013, we analyzed the temporal and spatial characteristics of surface water chemistry in Urumqi River Basin by using water chemistry analysis method and SPSS statistical software in combination with hydrological data. The results show that: (1) the TDS of Urumqi River is lower and the water is slightly alkaline; (2) water hydrochemical characteristics varied over the years, TDS is lower in summer than that in early spring, early summer and autumn; (3) the control ions of the surface water are HCO3-, Ca2+, SO42-, the icon concentrations decrease in the order: HCO3- > Ca2+ > SO42- > Cl- > Na+ > Mg2+ > K+ > CO32-; the main ions changed with years: Ca2+ and HCO3 are the main ions in dry season; while Ca2+, HCO3 and SO42- start to dominate in wet season for the dilution of abundant water; (4) the SO42- concentration suddenly rises in site 1 to site 2 due to the release of sulfuric acid and chloric acid in the gypsum horizon of the river segment; (5) the conclusion indicates that water-rock interaction movement is the main factor controlling the surface water hydrochemical properties.
