Abstract
Forest canopy leaf area index (LAI) is an important biological parameter and an evaluation index of the vegetation canopy. It is difficult to get LAI through direct inversion using Li-Strahler geometric-optical model (GOMS)[1,2]. In this paper, LAI is introduced into the GOMS model as an independent variable to substitute other canopy structure parameters. The verification results well demonstrated the accuracy of the modified GOMS model.
