    Abstract:
    The total NPP on the agricultural land has been estimated in the period of crop growth from 1996 to 2000 with the global 10-day composite NDVI data. The agricultural production is a part of NPP(Net Primary Production) on the agricultural land. By considering the relation between agricultural NPP and agricultural production, the conversion efficiency of agricultural production from agricultural NPP is made. The agricultural production is estimated based on agricultural NPP and the conversion efficiency. It shows that the accuracy of the model is very satisfactory. The model can be used in the operational crop production forecast.
