Using reflectance,transmittance,absorptance and reflectance of different spectral interval and disturbed by noises,comparison is made between the effect of retrieving foliar biochemical components with statistical models and that with physical models. The result shows that the physical model is more robust to spectral interval and noises than the statistical model. However,as far as the real retrieving values are concerned,especially when it comes to the inversion of water in fresh leaves,the statistical model is as good as the physical model. So in order to improve precision and efficiency in retrieving plant biochemical components,statistical and physical models should be used according to the purpose of research.
