Abstract：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 .
