| Abstract: | The technology of N isotope has been employed to recognize the source of NO3-ion in Zhangye city. The result show that the irrigation with the polluted water is the main source of NO3-in the shallow groundwater, in non-polluted irrigation area ,large-scale use of chemical fertilizers and the manure heap is the main source of NO3-in the around groundwater. |
