Abstract Leaf area index(LAI)is a crucial parameter of vegetation canopy structure and controls a number of
biophysical processes of vegetation. In this paper, a mixed model which combines the statistics model with the optical
model is presented to estimate LAI from Landsat-5 TM image data. Firstly, the model calculates and outputs a lookup
table (LUT) by useing of FCR model. and then, LAI mapping is conducted based on the empirical relations resulting from
the LUT. The results indicate that, being simple and easy to operate, the method can be used to estimate accurately
the LAI of reed marsh.
