“…In contrast, albedo is significantly lower in GRE than in CTL, with larger albedo differences in the northwest of the plateau. The lower albedo difference in the southeast of the plateau can be explained by the saturation of the albedo response to vegetation changes in the regions with higher values of vegetation fraction (Figure S3 in Supporting Information ; Feldman et al., 2023). Such spatial patterns of changes in growing season surface properties over the plateau since 2001 are overall consistent with those in previous studies (Ge et al., 2020; Tian et al., 2022; B. Q. Zhang et al., 2021).…”

The Loess Plateau is a highland area covering approximately 640,000 km 2 in north central China. Historical longterm deforestation and crop expansion, as well as the semiarid background climate, cause severe soil erosion and land degradation (Fu et al., 2011;He et al., 2006). Moreover, the plateau serves as the ecological safety barrier of the upper reach of the Yellow River. Soil erosion augments the sediment discharge of the Yellow River, increasing the flooding risk in densely populated areas downstream (Fu et al., 2017). To address these issues, China has carried out a series of large-scale ecological programs over the plateau, including the most influential "Grain for Green Program" (GFGP) initiated in 1999 (Bryan et al., 2018). Benefiting from the GFGP, the plateau has shown a significant greening trend since then, with the vegetation fraction increasing from 31.6% in 1999 to 59.6% in 2013 (Chen et al., 2015).Greening is beneficial to soil erosion control and, on the other hand, can influence the terrestrial water balance through biophysical processes (Piao et al., 2020;Zeng et al., 2018). Greening can facilitate surface evapotranspiration due to the larger leaf area, aerodynamically rougher surface and higher canopy conductance for tran-

“…In thermal risk landscapes, reductions in vegetation cover in urban ecosystems were found to be due to exposure to extreme thermal events or prolonged hot weather, and thus ESV may be reduced by anomalous changes in MET (Kabano et al, 2021). Feldman et al (Feldman et al, 2023) explained the negative effects of heat stress in terms of plant surface cooling capacity. In addition, this study also investigated the interactions between ESV drivers (ECO, MET and LULC).…”

The investigation into the impact of the Three Gorges Project on ecosystem services is crucial for ecological conservation, sustainable developmen and ecological management decisions. While numerous studies have focused on assessing the current state of regional ecosystem services, there remains a gap in research related to simulating the spatiotemporal changes and impact pathways. The objective of this paper is to uncover the direct and indirect impact pathways of ecosystem service value (ESV) in the reservoir area altered by the construction of the Three Gorges Dam project, by using the structural equation model (SEM) method. Additionally, this study aims to identify spatial and temporal changes in ecosystem service relationships over the 30 years before and after the dam's construction, utilizing self-organizing maps (SOM). The results of the study reveal that land use and land cover (LULC) factors predominantly exert direct negative effects on ESV. In comparison, socioeconomic development (ECO) and meteorological development (MET) factors have a nuanced impact on ESV, with MET factors exhibiting the strongest positive effect on ESV through the pathway MET → LULC → ESV. Furthermore, the application of SOM indicates that between 1990 and 2020, the patterns of ecosystem service bundles were spatially heterogeneous. Additionally, trade-offs and synergies between ecosystem service bundles are relevant to hydrological regulation services. These findings contribute to a comprehensive understanding of how various factors interact and influence ESV through multiple pathways. The intricate relationships among ecosystem services highlighted in the study are valuable for guiding ecological management at various scales.

“…Based on this, Froehlich modified it to adapt it to site‐specific under‐cloud atmospheric conditions and to observe long‐term seasonal variations in excess deuterium (Froehlich et al, 2008), suggesting that secondary evaporation under clouds is a local factor influencing stable isotope variations in precipitation. Recent studies have concluded that topographic features (Chen et al, 2021; Feldman et al, 2023; Huang et al, 2021) have a significant impact on under‐cloud evaporation, which is more intense in the plains than in the mountains (Chen et al, 2020; Zhu et al, 2021). Stable isotopes in central and eastern Asia are affected by below‐cloud evaporation, especially in the arid regions of central Asia and the northern Tibetan Plateau (Wei et al, 2018).…”

The study of below‐cloud evaporation effects under clouds in the Yellow River source region is of great significance for regional water resource generation as well as for water resource security in the arid and semi‐arid regions of northern China. In this study, we quantitatively assessed the evapotranspiration effect in the Yellow River source region from March to November based on the improved Stewart model. The study concluded that: (1) below‐cloud evaporation was slightly higher in summer than in other seasons (residual fractions of raindrop evaporation were 80.57% in summer, 81.12% in spring, and 84.2% in autumn, respectively); and (2) sub‐cloud evaporation diminishes with increasing altitude (residual fractions of raindrop evaporation were 83.09% in the western part of the area, 81.82% in the central part of the area, and 81.36% in the eastern part of the area, respectively). (3) The total linear index between study areas f and ∆d is 2.24, where f > 95%, it is 1.19; that is, the evaporation of raindrops increases by 1% and the reduction in the excess of mercury by about 2‰. (4) Local meteorological factors (temperature, precipitation, and relative humidity) and raindrop diameter have a cross‐influence on below‐cloud evaporation, with relative humidity having the most significant effect, with the highest correlation coefficient of 3.03 when relative humidity is less than 70%. The results of the study can provide a parameter basis for hydrological and climatic models in the Yellow River Basin.
