【Abstract】 In the paper, the state of researches on models for evaluating primary productivity of natural vegetation and crop yield at home and abroad is analyzed, the state of researching primary productivity of natural vegetation and crop yield by means of remote sensing technology is emphatically related. Various influencing factors such as meteorological and biological factors, etc.in the construction of model for evaluating primary productivity of vegetation are approached, and the parameters to be considered in establishing crop yield model coupling remote sensing information with plant photosynthetic mechanism information are also put forward.更多还原
