The relationship between estimation of vegetation carbon assimilation and remote sensing information

The relationships among vegetation carbon assimilation and remote sensing information such as NDVI(normalized difference vegetation index)，LAI(1eaf area index)，APAR (absorbed photosynthetically active radiation)，and TIR (thermal infrared radiation)were analyzed in this paper．It will be essential to establish the estimation model of carbonasimilation using remote sensing information and photosynthesis mechanism ，and serve as an independent comparison to more detailed eco-physiological models of biological proces ．
