英文摘要Vegetation change is closely linked to fluctuations in ecosystem water use efficiency (WUE). Although vegetation change (VC) involves the natural growth (NG) and the artificial restoration (AR), the individual impacts of these two processes on WUE remain poorly understood. This study used a recently developed ecohydrological model, integrating observed streamflow and multiple remote sensing data sets, to quantify the effects of NG and AR on WUE through three distinct vegetation scenarios in the Yellow River Basin (YRB) of China from 1998 to 2020. This region has experienced remarkable vegetation changes due to both natural and anthropogenic factors. The results show that, on average, VC led to a 13.3% increase in WUE in the YRB. However, NG and AR had contrasting impacts: the former contributed to a 7.4% decrease in WUE, whereas the latter caused a 22.4% increase in WUE. Spatially, NG reduced WUE in the southeastern YRB and the marginal areas of the Tibetan Plateau with somewhat higher precipitation but increased WUE in certain northern and northwestern regions of the YRB with lower precipitation. In contrast, AR generally reduced WUE in arid regions but increased WUE in wetter ones, showing effects opposite to those of NG. However, in specific areas like the Mu Us Sandy Land, a typical dry region, both NG and AR enlarged WUE. In all scenarios, the primary driver of WUE changes appeared to be net primary productivity rather than evapotranspiration. This study provides practical insights for sustainable water resource and ecological management. Plain Language Summary Changes in vegetation are closely linked to how efficiently ecosystems utilize water, a concept known as water use efficiency (WUE). Vegetation changes can occur naturally or as a result of human activities, such as artificial restoration; however, the impact of these two factors on WUE remains unclear. This study aims to separate their effects by conducting multi-scenario ecohydrological simulations in the Yellow River Basin (YRB) of China from 1998 to 2020. This region has experienced significant vegetation changes due to both natural processes and human intervention. The study found that, overall, vegetation changes led to a 13.3% increase in WUE in the YRB over the past two decades. However, natural vegetation growth (NG) and artificial restoration (AR) had opposing effects on WUE, Spatially, AR generally reduced WUE in arid regions but increased WUE in wetter regions, whereas. NG had the opposite effects in these areas. These contrasting roles of NG and AR were not observed in the Mu Us Sandy Land, a typical dry area, where both NG and AR contributed to increased WUE. In terms of causes of WUE, the variation in WUE is primarily driven by NPP rather than ET regardless of the way vegetation changes.
