The invention discloses a soil type identification method based on spectral curved surface matching. The method comprises the steps that firstly, profile depth interpolation processing and first-order derivation processing are conducted on the spectral reflectivity of each generation layer of to-be-identified soil profiles, and spectral curved surfaces of the to-be-identified soil profiles are generated; secondly, according to each soil profile in a soil sample database and the spectral reflectivity of each generation layer of the soil profiles, profile depth interpolation processing and first-order derivation processing are conducted on, and the spectral curved surface of each soil profile is generated; finally, spectral curve surface matching is conducted, and the soil types of the to-be-identified soil profiles are identified. In this way, depth interpolation processing, derivation processing, spectral curve surface generation and spectral curve surface similarity judgment are carried out on the basis of t
