Construction method and application of clinacanthus nutans seed source land classification model based on NIR spectrum

The invention relates to the technical field of traditional Chinese medicinal material identification, and particularly discloses a construction method and application of a clinacanthus nutans seed source land classification model based on an NIR spectrum. The construction method of the clinacanthus nutans seed source land classification model based on the NIR spectrum is characterized by comprising the following steps: collecting near infrared spectrums of clinacanthus nutans samples of different seed source lands; preprocessing the near infrared spectrum data; and carrying out modeling analysis on the preprocessed infrared spectrum data by adopting an SVM algorithm to obtain a clinacanthus nutans seed source land classification model. The invention provides the construction method of theclinacanthus nutans seed source land classification model based on the NIR spectrum for the first time. The clinacanthus nutans seed source land classification model constructed by the method can realize nondestructive, rapi
