| Abstract: | In this paper, the concept of crop yield model affected by water deficit is discussed. A model is established based on the remote sensing information from NOAA AVHRR,crop photosynthesis characteristic and meteorological data. In the model the crop stomatal conductance acts as an explicit parameter. The yield distribution of winter wheat in North China Plain is demonstrated as an example. It shows that this model possesses higher accuracy than other existing models. |
