| 英文摘要 | The Loess Plateau, a critical region for ecological restoration in China, has experienced extensive vegetation recovery since 1990s, yet its cooling effect on surface warming remains debated. Combining multi-source satellite observations (MODIS LST and GLASS LAI) with climate data, this study quantifies the spatiotemporal interplay between vegetation greening and land surface temperature (LST) dynamics across the Loess Plateau from 2001 to 2020. Results reveal a 0.038 m2 & sdot;m- 2 & sdot;yr- 1 increase in annual LAI, with 72.89 % of the region showing significant greening. Despite this, LST exhibited an overall warming trend (0.027 degrees C & sdot;yr- 1), driven by pronounced nocturnal heating (0.064 degrees C & sdot;yr- 1) that offset daytime cooling (-0.011 degrees C & sdot;yr- 1). Seasonal analysis demonstrated summer cooling (-0.050 degrees C & sdot;yr- 1) but accelerated warming in spring (0.074 degrees C & sdot;yr- 1), autumn (0.050 degrees C & sdot;yr- 1), and winter (0.011 degrees C & sdot;yr- 1). Structural equation modeling identified air temperature (path coefficient: 0.79) as the dominant LST driver, while vegetation greening (LAI) exerted a significant yet spatially heterogeneous cooling effect (-0.43). During the daytime, LST is primarily influenced by air temperature (0.71) and LAI (-0.62). While, at nighttime, it is mainly governed by air temperature (0.72) and precipitation (0.48), with no significant relation to LAI (-0.08). Cooling efficiency peaked in humid eastern zones with high LAI gains but diminished in arid northwestern and urbanized areas due to energy balance alterations. Residual analysis indicates that vegetation degradation significantly accelerates surface warming (2001-2020 mean LST increase of 0.055 degrees C & sdot;yr- 1, with 61.0 % attributed to vegetation degradation), while vegetation greening induces a pronounced diurnal asymmetry: daytime LST shows a significant cooling (-0.024 degrees C & sdot;yr- 1, with a cooling contribution of -187.7 %), but nighttime cooling is limited (nighttime LST increase of +0.045 degrees C & sdot;yr- 1, with only 23.2 % attributed to greening), resulting in a slight overall increase in mean LST (+0.010 degrees C & sdot;yr- 1). These findings imply the necessity of region-specific ecological strategies to optimize vegetation climate-regulating potential under global warming. |
