Abstract Fundamental knowledge is necessary for establishing a statistical model between LAI and vegetable
indices to perform the inversion of LAI with remotely sensed data. The authors processed the canopy spectral data
of winter wheat in Beijing area obtained by ASD Spectrometer with spectral response function of the TM sensor,and
got the canopy NDVI of the wheat. Two different kinds of non-linear statistical data of LAI and NDVI were
constructed in this paper. The experimental results show that there exists a close exponent correlation between
LAI and NDVI.
