Abstract The determining methods of stable carbon and nitrogen isotopes are briefly summarized and the application of stable isotopes to ecosystems about carbon sources, energy flow, trophic structure, the bioaccumulation of pollutants and the stability variations of ecosystems are systematically discussed. Furthermore, the authors propose the application of the stable isotopes in brown tide, environmental pollution, establishing ecologic dynamics models and molecular tracers.
Key words stable carbon isotopes;stable nitrogen isotopes;ecosystem;trophic structure;energy flow;environmental pollution
