Degenerated grassland restoration evaluation method and system based on aerial photography and satellite remote sensing

The invention belongs to but is not limited to the technical field of satellite remote sensing, and particularly relates to a degraded grassland restoration evaluation method and system based on aerial photography and satellite remote sensing, aerial photography observation is performed on degraded restored grassland in a research area based on a FragMap unmanned aerial vehicle aerial photography analysis system, fine grassland vegetation coverage information is obtained, and a grassland restoration evaluation result is obtained based on a GEE Google engine cloud computing platform. A long-time sequence (2000-2022) high-temporal-spatial-resolution NDVI data set (the temporal resolution is 16 d, and the spatial resolution is 30 m) is obtained by combining an STARFM high-temporal-spatial data fusion algorithm, and the grassland coverage temporal-spatial change process in the degraded grassland restoration process is carried out, so that a theoretical basis is provided for degraded grassland restoration strategy
