Abstract: Considering the parameters of remote sensing information and plant eco physiological characteristics,the crop yield estimation model was set up based on remote sensing information and plant photosynthesis model.Among them,Absorbed Photosynthetic Active Radiation(APAR),Crop Photosynthetic Assimilation Potential(CPAP) reflecting crop photosynthetic time,and photosynthetic rate were calculated by remote sensing information and meteorological data.In the typical regional research area,the model has been applied to study regional crop yield distributions and the result shows the model has better precision.

Key words: remote sensing, crop photosynthesis, crop yield, yield estimation model
