To achieve non-destructive evaluation of wood properties, we took plantation wood of Chinese fir as an example, air-dried density, microfibril angle(MFA) and longitudinal modulus (E L) were experimentally measured on the same non-standard small clear wood sample. Three prediction models of E L were constructed based on density and MFA. The accuracy of these models was different. Compared with the single variable models, the prediction model from the ratio of density and MFA has the highest coefficient of determination, and minimum residual standard deviation. The model confirms that both density and MFA are the main factors influencing tensile modulus. Regarding to Chinese fir, the most critical factor is density.
