| 英文摘要 | Climate change and large-scale ecological restoration have significantly enhanced China's vegetation coverage, thereby profoundly altering the spatiotemporal patterns of water availability. However, previous studies often treated vegetation greening solely as a contributor to water loss, neglecting its role in enhancing local and downwind precipitation through moisture recycling, leading to potential biases in evaluating hydrological impacts of greening. To address this gap, we conducted a first-order, offline diagnostic assessment of the effects of vegetation greenness change on evapotranspiration (ET), precipitation (P), and water availability (P-ET) by integrating a remotely sensed ET model, a moisture-tracking dataset, and the Budyko framework. Our results indicate that greening has increased ET over 65.7% of China's land area, with an average increase of 12.85 mm yr-1. Importantly, approximately two-thirds of the additional ET is recycled and returned as precipitation within China. Neglecting the moisture recycling effect leads to an average underestimation of annual runoff by 5.4 mm yr-1 (3.66%) nationwide. Spatially, the largest absolute underestimation occurs in the middle-lower Yangtze River Basin, while the largest relative impact is found in the middle reaches of the Yellow River and Songliao River Basins. We also found strong heterogeneity in evaporative moisture redistribution across China's nine firstlevel basins. Seven basins are dominated by moisture export to downwind basins or beyond China, whereas the remaining two are characterized by local recycling. This study underscores the importance of considering moisture recycling when assessing the hydrological impacts of large-scale vegetation changes. |
