| 摘 要： | 在滹沱河上游区采集了河水、地下水、泉水、水库水样品,分析了各类水的氢、氧、氮同位素和化学特征,并将氢氧稳定同位素与平原区大气降水进行了对比,分析了沿流程的变化,识别了硝酸盐来源。结果表明:滹沱河源区河水、地下水和泉水与平原区大气降水的同位素组成差别明显;滹沱河水进入水库以后,水库水受到明显的蒸发浓缩作用,也可区别于平原区大气降水;水样的NO3-含量变化在1.68~87.4 mg/L之间,大部分样品的1δ5N值大于8‰,指示水中NO3-来自污水或粪便。

| Abstract: | Samples were collected in river,groundwater,spring and reservoir,up-stream of Hutuo River for analysis of hydrogen,oxygen and nitrogen isotopic and chemical compositions, and comparing with precipitation isotopes in the plain area for stable hydrogen and oxygen isotopes.The stable hydrogen and oxygen isotopes along the flow distance and identification of sources of nitrate in water were analyzed.Results indicated that significant differences in isotopic compositions existed bewteen different kinds of waters and precipitation in the plain area.Reservoir water showed great difference from precipitation in the plain area due to evaporation after Hutuo River flowing in the reservoirs.Nitrate contents of samples ranged from 1.68 to 87.4 mg/L.Most of samples had nitrogen-15 values of greater than 8 ,indicating nitrate in water was derived from sewage or animal wastes. |
