首先给出利用遥感信息结合作物光合生理特性研究作物产量水分胁迫模型的一般性概念，然后论述作物产量水分胁迫模型中作物蒸散和光合作用的关系。建立以作物蒸散为显参的作物产量水分胁迫模型；对模型的参数给出求解公式，利用遥感信息反演模型参数。最后利用发展的作物产量水分胁迫模型对华北平原典型区进行作物产量填图，将本模型与作物产量经验模型的１９９７年计算结果进行比较，发现本文发展的模型有可比的精度。
Firstly, the general concept of crop yield stress model using remote sensing information combined with photosynthetic physiological characteristics of crop was given, and then the relationship between crop evapotranspiration and photosynthesis in crop yield stress model was discussed. The crop yield stress model with crop evapotranspiration was established. The formula of the model parameters was given and the model parameters were retrieved by remote sensing information. Finally, the crop yield and water stress model was used to map the crop yield in the typical area of North China Plain. Comparing this model with the 1997 crop yield empirical model, we found that the model developed in this paper has comparable precision.
