Abstract This article is based on the effects of wavelet transform in the near infrared(NIR)quantitative model ：denoising，eliminating background interference，data compression and variable selection，with chemometrics being applied in the near infrared model，it reviewed，in the past 10 years，the wavelet transform in near infrared quantitative model for applications.With NIR technology continuing to evolve and improve，the wavelet transform will take its advantages to support modeling and applications.
