基于遥感技术及时获取小麦倒伏信息，对于农业部门指导小麦倒伏后的农业生产、灾害评估等具有重要意义。在鲁西、鲁西南地区小麦倒伏样方调查的基础上，选用小麦倒伏前后两期环境与灾害监测小卫星数据，探讨了利用遥感影像监测小麦倒伏的基本理论和方法。首先，根据小麦灌浆期不同组分的光谱特性，解释了倒伏小麦光谱变化的原因；其次，分析了倒伏小麦在可见光和近红外波段的光谱反射特点，寻找小麦倒伏遥感监测的敏感波段；最后，利用敏感波段建立植被指数，讨论了小麦倒伏发生程度的遥感监测问题。

Getting wheat lodging information immediately under the help of remote sensing is very impor-tant for agricultural department to guide produce and assess disaster after wheat lodging .On the basis of wheat lodging sample surveys in west and southwest Shandong Province , this research selected two images from the environment and disaster monitoring satellite before and after the wheat lodging , and discussed the basic theory and methods for remote sensing monitor of wheat lodging .Firstly, the cause of spectral changing of lodged wheat was explained based on the spectral characteristics of different components of wheat at filling stage ;Sec-ondly , the spectrum reflection characteristics in visible and near infrared bands of lodging wheat were analyzed to look for the sensitive bands;Finally, the vegetation index was set up with the sensitive bands , and the re-mote sensing monitoring of wheat lodging level was discussed .
