[Hydrochemical characteristics of three kinds of wetland in Gongbiela Basin].
The study on the hydrochemical characteristics of three representative kinds of wetland in Gongbiela Basin showed that in the water of test wetlands, HCO3 - was the dominant anion, accounting for 81.91% - 85.46% of total anions, and Ca2+ was the dominant cation, accounting for 56.80% - 69.32% of total cations. The hydrochemical type belonged to that of bicarbonate calcium. In the three kinds of wetland, water pH ranged from 6.2 to 7.1, mineralization degree ranged from 112.56 to 461.23 mg x L(-1), and hardness ranged from 14.31 to 148.53 mg x L(-1). On the whole, the water quality of the wetlands met the grade 1 and grade 2 national environmental water quality standards, but the Fe and Mn contents exceeding the standards influenced the water resource quality of this area. The spatial and temporal changes of hydochemical characteristics of the wetlands and the trace element contents in the water were also discussed and analyzed.
