为确定县域尺度的烤烟种植面积,进而为烤烟生产决策提供更准确的数据支撑,选取湖南省茶陵县为测试点,研究Sentinel-2A数据对烤烟种植面积遥感监测的效果。并对2019年6月份湖南省茶陵县烤烟、林木、灌木草地、道路及水体的光谱特征和植被指数进行了分析,采用决策树分类方法提取烤烟种植区域并绘制植烟区的域图。精度验证结果表明,Sentinel-2A数据对湖南省茶陵县烤烟种植面积遥感监测总体分类精度达90.29%,与实际调查的年度种植面积相比,误差为3.7%,可满足烤烟生产管理的实际需求。

In order to determine the flue-cured tobacco planting area at a county scale and to provide more accurate data for the production decision of flue-cured tobacco, the tobacco-planting area in Chaling County of Hunan Province was measured, and the effect of corresponding Sentinel-2A data gathered by remote sensing was investigated. The spectral characteristics and vegetation indices of flue-cured tobacco, trees, shrub grasslands, roads and water bodies in Chaling County in June 2019 were analyzed to extract the flue-cured tobacco planting area us...
