The results shows that the 1st derivative values increase in the green edge(500~560 nm) and decrease in the red edge (680~760 nm) with DI increasing. The ratio of the sum of derivative within the red edge (SDr) and that within the green edge (SDg) has a good correlation with the healthy or diseased crops 12 days before symptoms appearing. Therefore, the derivative vegetation index SDr/SDg can be used to identify crops disease information effectively., authors=null, authorsList=null, authorCompany=null, correspAuthors=null,

articleAbstract=人工田间诱发不同等级小麦条锈病，在不同生育期测定染病冬小麦冠层光谱和相应的病情指数。对小麦冠层一阶微分光谱进行分析，结果表明随病情指数增大，一阶微分光谱在绿边（500～560 nm）内逐渐增大，在红边（680～760 nm）内逐渐降低。红边内一阶微分总和（SDr）与绿边内一阶微分总和（SDg）的比值，能够在症状出现前12 d识别出健康作物与病害作物。因此，微分植被指数SDr/ SDg能够较为理想地识别作物病害信息。, authors=李京1，2,陈云浩1，2,蒋金豹1,蔡洪春1, authorsList=李京;陈云浩;蒋金豹;蔡洪春, authorCompany=1北京师范大学资源学院 北京 2国家遥感中心全球变化与可持续发展研究部 北京, correspAuthors=null, authorNote=null,
