将遥感手段和动力估产模型相结合，即通过ＮＯＡＡ卫星获得有效绿度模式；通过绿度—叶面积关系式，估算水稻群体叶面积指数；依据水稻生物量分配规律及环境条件对其的影响，估算水稻各器官的干重，取得了较好的模拟效果．
Combining remote sensing method and dynamic estimation model, the effective greenness model was obtained through NOAA satellite. The leaf area index of rice population was estimated by the relationship between greenness and leaf area. Based on the effect of rice biomass allocation and its environmental conditions, Estimated dry weight of various organs of rice, and achieved good simulation results.
