| description | The invention relates to the technical field of grassland degradation evaluation, and provides a grassland degradation evaluation method and device based on remote sensing data, equipment and a medium. The method comprises the following steps: calculating the maximum vegetation coverage of each to-be-evaluated pixel in a to-be-evaluated region in an evaluation time period and the climate characteristic value of each to-be-evaluated pixel, performing climate type grouping on the to-be-evaluated pixels according to the climate characteristic value, and calculating the climate type of the to-be-evaluated pixels according to the calculated maximum vegetation coverage of each to-be-evaluated pixel. And determining the maximum value of the vegetation coverage corresponding to each climate type group as an evaluation criterion, and calculating the grassland degradation index of each to-be-evaluated pixel for evaluating the grassland degradation degree of the to-be-evaluated region. The grassland in the historical op |
