摘　　要：The visible and near infrared(NIR)(350-2500 nm)spectra and the MOE of 438 small clear wood samples from Chinese fir,eucalyptus and poplar 72 were measured.Using partial least-square(PLS)modeling,the NIR spectra could be used to predict MOE and MOR of the clear-wood samples from Chinese fir and eucalyptus solid wood.NIR spectra could only be used to predict MOE but not MOR of poplar clear-wood samples.With the exception of MOR of poplar clear-wood samples,the correlations between NIR and the mechanical properties are very strong,and the calibration and test correlation coefficients are both above 0.80.The visible and near infrared （NIR） （350-2500 nm） spectra and the MOE of 438 small clear wood samples from Chinese fir, eucalyptus and poplar 72 were measured.
