The invention discloses a method for evaluating the quality of saffron based on a near infrared diffuse reflection spectrum technology. The method comprises the following steps: (1) laboratory determination; (2) constructing a saffron quantitative analysis model by combining near infrared spectroscopy with chemometrics analysis; (3) model evaluation; (4) model verification; and (5) unknown sample prediction. According to the present invention, the near infrared spectroscopy is combined with the chemometrics to carry out the rapid evaluation method research of the saffron imported medicinal material standard, such that the rapid and nondestructive quantitative detection of the saffron can be achieved, the detection cost of the detection institution and the enterprise can be significantly reduced, and the scientific saffron medicinal material quality evaluation method is established; a saffron medicinal material quality evaluation system is perfected, a scientific basis is provided for safe and reasonable appli
