Abstract：River system is important to global biogeochemical cycles, and land erosion is the main input channel to the ocean. Natural weathering is the main force of the provenance of substance in the water, while, the impacts of human activities make the river pollutants more complex. Relying solely on the major ion composition is not enough for distinguishing different sources of substances in the river, while stable carbon and sulfur isotopes can help to trace the source of the matters in the river. This paper reviews  research and analytical methods on carbon and sulfur isotopes in the contemporary river systems, and discusses the development of the coupling between carbon and sulphur isotopes in the future.

Key words：rivers；carbon isotope；sulphur isotope；carbon-sulphur coupling
