一、研究介绍近年来,使用卫星遥感数据进行作物估产的研究已显得十分重要。土地资源卫星广泛应用于这一领域。但是,对于大尺度的作物估产来说,NOAA 综合植物指标(地表绿色植物叶绿素含量指标)数据较之其它卫星数据具有更大的优越性。本文作者以前的研究表明,NOAA 综合植物指标 I. Introduction of Research In recent years, it has become very important to study crop yield estimation using satellite remote sensing data. Land resources satellites are widely used in this area. However, for large-scale crop yields, the NOAA composite plant index (chlorophyll content indicator of surface green plants) provides greater advantages than other satellite data. The previous study by the authors showed that NOAA integrated plant indicators
