| Abstract: |
| According to the relationship between the growing characters and yield of winter wheat, it was determined that the best stage to monitor the yield by remote sensing was from blossom to filling. GDVI was derived and analyzed from the TM image, and the model was set up to express the relation between GDVI and yield of wheat, which was available to accomplish the estimation of yield. The results showed that the estimating precision was more than 88.90%. |
