The invention provides a water quality BOD5 measurement influence factor analysis method based on a three-dimensional fluorescence spectrum, and the analysis method comprises the following steps: 1, taking a BOD5 standard solution prepared by taking glutamic acid and glucose as solutes as an experimental subject in an experiment, enabling the mother liquor concentration to be 210mg/L, respectively diluting the mother liquor into 21 standard solution samples with the concentrations of 5mg/L, 10mg/L, 20mg/L, 50mg/L, 80mg/L, 100mg/L, 120mg/L, 150mg/L and 180mg/L through pure water, and determining the concentration of the standard solution samples to be 250mg/L, 10mg/L, 20mg/L, 50mg/L, 80mg/L, 100mg/L, 120mg/L, 150mg/L and 180mg/L; the method comprises the following steps: detecting an experimental object by adopting a domestic prismatic F98 fluorospectro photometer; the three-dimensional fluorescence spectrum data in the experiment is subjected to data preprocessing by adopting three methods of blank deduction,
