摘　　要：以上思县为研究区,以各个地物光谱特征的差异为着入点,利用GF-1卫星数据资料,采用监督分类和卫星NDVI影像差值的遥感方法,提取研究区的甘蔗种植信息。结果表明:利用卫星遥感技术开展甘蔗种植面积估算和长势监测与实际情况基本相符,面积估算准确度为93%,长势监测与实际生长情况基本一致。Shangsi County is taken as the research area in this paper, then taking the differences in spectral characteristics of various features as the entry point, using GF-1 satellite data, supervised classification, and remote sensing method of satellite NDVI image difference to extract sugarcane planting information in Shangsi. The results show that the estimation of sugarcane planting area and monitoring of sugarcane growth by satellite remote sensing technology are basically consistent with the actual situation, the accuracy of area estimation is 93%, and the monitoring of sugarcane growth is basically consistent with the actual situation.
