水稻遥感动力估产模拟初探

A Preliminary Study on Remote Sensing Dynamic Simulation for Estimating Rice Yield

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影响，估算水稻各器官的干重，取得了较好的模拟效果。

In this paper,the authors combine the remote sensing technique withdynamic estimating yield model,e.g.to acquire effective green index through NOAAsatellite data,estimate the index of leaf area in a certain rice unit through therelationship between green and leaf area,and estimate dried weight of each riceorgan on the basis of distributive law of rice biological quantity and the imput ofsurrounding conditions.A satisfactory simulaty effect is obtained.
