英文摘要Cropland changes modulate local temperature by altering terrestrial biophysical properties, yet the global sign and magnitude of this impact remain uncertain due to fragmented distributions and complex natural land-cover conversions. Using satellite remote sensing (2000-2020), we quantify sub-pixel-level biophysical effects on land surface temperature from global cropland expansion into both forest and non-forest vegetation. Our results show that cropland expansion into non-forest vegetation (87% of global conversions) induces spatially heterogeneous temperature responses. Summer cropland conversions caused net global cooling (-0.002 +/- 0.000 degrees C per five years), with 50% attributable to non-forest vegetation replacement. Boreal regions (40 degrees N-50 degrees N) exhibited pronounced cooling (-0.02 +/- 0.001 degrees C per five years), while tropical zones (0 degrees S-10 degrees S) experienced localized warming (+0.07 +/- 0.001 degrees C per five years). Winter cropland conversions contributed minimally to boreal temperature changes but amplified tropical warming (+0.07 +/- 0.002 degrees C per five years; 10 degrees S-20 degrees S). Temperature sensitivity to cropland fraction varied asymmetrically with background land cover: Complete non-forest vegetation replacement in the Northern Hemisphere yielded stronger summer cooling (-0.06 degrees C) than warming from reversed conversions (+0.02 degrees C), whereas maximum forest replacement warming (+0.78 degrees C) exceeded its cooling benefits (-0.55 degrees C). These findings highlight the summer cooling capacity in boreal non-forest vegetation replacement and reveal the risk of tropical cropland expansion to climate mitigation.
