The invention relates to a trace element spectrum method for tracing a phoenix-tailed chicken, and belongs to the technical field of phoenix-tailed chicken breed and origin traceability. According tothe trace element spectrum method, the varieties and the contents of trace elements in the phoenix-tailed chicken and a white-feather chicken are determinated, and then multiple comparative analysis is performed to obtain the varieties of the trace elements having significant content differences in the phoenix-tailed chicken and the white-feather chicken; then, variables that are effective for variety discrimination are obtained through principal component analysis, system clustering analysis and discriminant analysis, a discriminant model is established, and the validity of the model is verified, so that a trace element spectrum having effective discriminative power for a phoenix-tailed chicken sample and applicable to phoenix-tailed chicken traceability is obtained. By the trace elementspectrum method, the trace
