| 英文摘要 | Urban vegetation regulates local thermal environments, yet rapid urbanization has simultaneously driven widespread browning that undermines these benefits. Although greening is widely promoted as a heat-mitigation strategy, its capacity to mitigate the warming from browning remains unclear, particularly given the potentially asymmetric thermal responses of these processes. Here, using 30m-resolution Landsat data (2000-2024), we mapped greening and browning across the Yangtze River Economic Belt, quantified their thermal effects, and explored the underlying drivers. We found that browning (35.1 %) outpaced greening (21.6 %), with the former concentrated in expansion zones and the latter in urban cores. These changes produced strongly asymmetric thermal effects: while browning increased daytime land surface temperature (LST) by 0.44 degrees C, greening reduced it by 0.59 degrees C, offsetting 134 % of the warming. However, the cooling effect of greening was limited in the two sub-periods (2000-2012 and 2012-2024) and rapidly expanding cities, and even leading to nighttime warming. Vegetation greenness changes and the area of browning emerged as primary drivers of these outcomes. Our findings highlight the limitations of relying solely on greening strategies for urban heat mitigation, and emphasize the urgent need to curb browning through proactive land-use planning to support climate-resilient urban development. |
