The destruction of arable land caused by coal mining in grain compound areas is a major bottleneck restricting production increase. spatiotemporal correlation between the decline cultivated quality and crop growth deterioration due to subsidence still needs be clarified. This study employed CDR AVHRR NDVI dataset applied trend analysis methods extract vegetation cover information from 1982 2022. It also explored relationships temperature precipitation. found following: (1) Over past 41 years, area showed significant upward trend. Specifically, average annual rate was 51.85%, while corresponding rates for 10 km buffer area, 20 check (CK) were 65.91%, 65.86%, 68.09%, respectively. start growing season (SOS) winter wheat control advanced 49 ± 1.5 days 65 days, respectively, length (LOS) extended 59 72 For summer maize, SOS 11 15 LOS 17 19 exhibited positive temperature. coefficient 0.6865 (p < 0.01); zone, it 0.5937 0.01), 0.6775 (CK), 0.6591 0.01). results this can provide data support collaborative rehabilitation source reduction areas, as well restoration damaged farmland.
