Abstract: There are mainly four types of models for estimating vegetation productivity and biomass, including empirical, physical, semi empirical and integrated models. The application of these models is limited by factors such as atmosphere, background, geography, vegetation cover and structure. The rapid development of remote sensing technique, especially the use of thermal infrared,microwave, laser remote sensors and the techniques such as multi angle, hyperspectral and high resolution remote sensing, will be helpful to eliminate or reduce the effect of these factors.
