【Abstract】 [Objective] This study aims to review the development of composite fingerprinting technique and provide support for the study of sediment sources in the Loess Plateau. [Methods] The theoretical basis of composite fingerprint tracing technique was reviewed. The development process, model algorithm and uncertainty analysis of various fingerprint factors(physical tracers, radionuclides, geochemical tracers, mineral magnetics, properties of organic matter, stable isotopes of organic carbon and nitrogen, plant pollen and biomarkers) were discussed in detail. [Results] A series achievements have been made in studying the sources of sediment and quantitatively describing the development of erosion process in the Loess Plateau by using the spatial and temporal differences of fingerprint factors. [Conclusion] Most existing studies on the Loess Plateau focused on the application of sediment tracing methods. Further studies are needed in the area of mix model correction, methods comparison and fingerprint factor conservation in the future.更多还原
