| 摘 要： | 在水稻遥感估产中,直接基于光谱与水稻产量间关系和基于水稻生长模拟这两种估产方法都能取得较高的精度,但都存在着一些不足之处。通过试验研究了如何充分发挥两种方法的长处,来弥补它们的不足,从而形成一种新的、更好的估产方法,为准确、方便、快速地估测水稻产量提供了可能。

| Abstract: | The rice yield estimation could be based on the relationship between spectral variable and yield, and the YLDMOD (crop weather model) having high accuracy. Both of them had their advantages and defects needed improve. In this paper, a new method of combining the advantages of the two methods was made and discussed, and the new method has the advantages of high accuracy and high speed. |
