2013年5—11月对松花江汤旺河下游10个断面主要离子进行定期监测分析. 结果显示: 汤旺河下游水域年离子总量平均值为98. 31 mg/L, 属弱矿化度水, 主要阴阳离子分别为HCO3 -与Na+( K+) , 水质类型为CⅡNa.2013年河水年内离子总量变化明显, 离子组成变化亦显著. 其中HCO3 -与SO4 2-呈负相关关系, Cl-基本不变.不同河段除Ca2+、 Mg2+差异显著外, 各离子组成及离子总量则无显著差异. 分析采样点离子总量与离子组成的相关性可知, 离子总量越高, SO2-4 、 Na+( K+)所占比例越大, HCO3 -、 Ca2+所占比例越小.

Through measuring major ions of Tangwang River water every ten days from May to November in 2013, we con-cluded that the average total ion content of the river was 104. 97 mg/L and the water of Tangwang River was low salinity wa-ter. The major anion and cation were HCO3 -and Na+ respectively. The water type was CⅡNa, according to Alekin classi-fication. The total ion content changed significantly in 2013, and the ion composition of the river changed significantly with the proportions of HCO3 - and Mg+ Negative correlation. In addition to that Ca2+ and Mg2+ had significantly difference, the composition and the total ion showed no significant differences. By analyzing the relationship between the ion composi-tion and total ion content in Tangwang River, we concluded that the higher total ions concentration the less the proportion of HCO3 -, Ca2+ and Mg2 .
