摘要
分析了国内外自然植被第一性生产力和作物产量模型的研究状况 ;重点阐述了国内外利用遥感技术对自然植被第一性生产力和作物产量的研究状况 ,探讨了植被第一性生产力建模中气象、生物等各项影响因子 ;提出了建立遥感
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.
