The nitrogen cycling in the natural environments has been seriously disturbed due to the industrial and agricultural development and the population increase. Moreover, some nitrogen oxides and hydrides produced in the imbalanced process of nitrogen cycling,such as N2O,NO3-,NO2 -,NH3,NH4+, are the main contributors for three major environmental problems of global warming, water eutrophication and acid rain. As an effective tracing method, stable nitrogen isotope is significant for studying the nitrogen cycling, especially for identifying source of nitrogen pollution. This paper has briefly summarized the nitrogen isotope fractionation effect, reviewed and discussed its applications for tracing and identifying nitrogen sources in the soil-plant-groundwater system and the atmosphere system, and proposed the prospective of the research on the nitrogen isotope for tracing environmental pollution sources.
