摘　　要：在获取广西甘蔗种植空间分布遥感信息及结合大量田间调查的基础上,应用EOS/MODIS遥感数据资料对2008年初寒害冻害发生前、后及2007年同期的广西区域甘蔗NDVI值变化进行比较、分析,结果表明:应用EOS/MODIS遥感数据资料开展甘蔗寒害冻害监测具有重要意义。Based on the sugarcane growing distribution information by remote sensing in Guangxi and a lot of field investigations, the values of sugarcane NDVI before, during and after the period of chilling and freezing injuries in early 2008 and the same term in 2002 were compared and analyzed with the data of EOS/MODIS remote sensing, the result showed that monitoring sugarcane chilling and freezing injuries by use of remote sensing technique is of great economic significance.
