- Abstract:
-
In order to find out the current situation of hydrology and water chemistry of rivers in Gobi region, we went to the Tarim Basin and the south of the Qaidam Basin in September 2014 and surveyed 12 typical rivers. We reached our goals through collecting water samples, measuring the flow rate in the field, acquiring data analyzing samples in laboratory. The results showed that: (1) the impermeable channel and reservoir built in Gobi region had the adverse influence on normal development of rivers; (2) the contents of F- were more than 1 mg/L, so it couldn’t meet the drinking standard, however, F- and Ca2+ showed negative correlation; (3) cation intensity of water decrease in the order: Ca2+ > Na+ > Mg2+ > K+, the mainly chemical type of river water were Cl-·SO42-·HCO3-/Na+·Ca2+; (4) the total dissolved solid (TDS) in river water was general high, and ranged between 718.3 mg/L and 8 254.1 mg/L; pH varied between 7.44 and 8.07, and presented the alkalinity.
