Summary: | The invention discloses a satellite remote sensing-based sugarcane freezing injury early-stage identification method, and belongs to the technical field of sugarcane freezing injury identification, and the method comprises the following steps: S1, simulating freezing injury conditions of healthy sugarcane leaves at 0 DEG C in a laboratory, and obtaining hyperspectral curves of the sugarcane leaves under different freezing injury durations; s2, performing characteristic analysis on the hyperspectral curve obtained in the step S1 to obtain a spectral range sensitive to freeze injury response, and determining a satellite wave band corresponding to the spectral range; s3, by taking the spectral range of the satellite wave band obtained in the step S2 as a reference, constructing a spectral index sensitive to the early freezing injury of the sugarcane leaves; and S4, acquiring a satellite remote sensing image of the monitoring area, calculating the spectral index constructed in the step S3, and comparing the spect |
