| 摘 要： | 利用气象卫星NOAA AVHRR资料，反演出农作物生育期内每日和旬度的NDVI数据，分析了NDVI时间曲线的波动与农作物生长发育阶段及农作物长势的响应规律，并以华北冬小麦为例，探讨了NDVI在冬小麦中生育期的积分值与农作物单产之间的相互关系。结果表明，利用长时间序列的NDVI数据，结合作物的物候历，可以实现作物长势的遥感监测和产量遥感估算。

| Abstract: | Growing situation monitoring and yield estimation of crops is an important region of agriculture research using remote sensing. Electronic waves reflected or emitted by crops and surface objects passed through atmosphere and reached the surface of sensors onboard satellite. The variation of the waves can be recorded and useful indexes reflecting growing status of crops can be created with proper procession and analysis. Therefore, continuously monitoring of growing status of crops can be carried out success... |
