“…Vegetation restoration and check dam construction have significantly controlled soil erosion on the Loess Plateau (Fu et al, 2017; Shi et al, 2020). Z. Li et al (2019) noted that check dams on the Loess Plateau reduced the sediment load in the Yellow River by approximately 0.1–0.2 × 10 9 t a −1 . Moreover, the dams currently retain a total of 28 × 10 9 t of water and soil.…”

Restoring vegetation and constructing check dams are important measures for controlling water erosion in slope‐gully systems. However, percolation through the dam body could lead to shortened runoff paths in the gully. Moreover, the synergistic effects of vegetation patterns and siltation‐induced runoff path length decrease (RPLD) in slope‐gully systems on reducing water erosion remain unclear. In this study, 20 physical models of slope‐gully systems were constructed to quantitatively evaluate the synergistic effect of these measures under simulated rainfall. The models included four slope vegetation patterns (no vegetation, up‐slope, middle‐slope, and down‐slope) and five levels of RPLD in the gully (0, 1, 2, 3, and 4 m). Owing to synergistic effects, combined measures led to a more considerable reduction in soil and water loss than a single measure. Furthermore, the synergistic effect was related to vegetation patterns and shorter siltation‐induced runoff paths. The mean synergistic effect produced the following runoff yield order: down‐slope (2.84%) > middle‐slope (2.81%) > up‐slope (1.78%); and 4 m (3.18%) > 3 m (2.66%) > 2 m (2.29%) > 1 m (1.78%). The sediment yields were in the following order: down‐slope (18.15%) > middle‐slope (12.63%) > up‐slope (6.67%), and 4 m (14.56%) > 3 m (12.82%) > 2 m (11.73%) > 1 m (10.82%). These results suggest that revegetation of the lower parts of the slope, along with check dams, will be more effective for controlling soil erosion. Such synergistic effects should be considered in future soil erosion modeling.

“…As a combination of high research heat and high erosion intensity (Hu et al., 2019), Loess Plateau (LP) in China, has been suffering serious soil erosion, and the erosion in this region has occurred in over 60% of the area, which is a typical area for studying soil erosion and SOC storage changes (Chang et al., 2012). Studies have shown that the LP has achieved a transition from a carbon source to a carbon sink due to the implementation of large‐scale ecological conservation and restoration programs, such as the Grain for Green (GFG) and the regional total amount of carbon is about 9.6 million tons (Li et al., 2019). The influence of soil erosion on the carbon cycle is still associated with high uncertainties (Kuhn et al., 2012).…”

Soil organic carbon (SOC) detachment and transport, especially in the eroded areas, has a profound influence on the global carbon cycling and climate. However, soil organic carbon erosion still has a high uncertainty on land C balance components for lack of a detailed capture of local topography and quantitative factors. Here, aimed at the Loess Plateau (LP) area with undulating terrain, we presented an unprecedentedly high resolution (90 × 90 m) soil erosion model, Revised Universal Soil Loss Equation and the contributions of vegetation to SOC erosion changes were quantified through factorial simulation. Our findings demonstrate soil organic carbon which induced a substantial lateral redistribution by soil erosion was 10.46 Tg C yr−1 over the period 2000–2017, which was a decrease of 21% compared with that before 2000. In the fixed‐NDVI scenario, after 2000, SOC erosion increased by around 7% compared with that before 2000. Agriculture and shrub are the primary source of regional soil erosion and SOC erosion. These findings highlight the importance of lateral transport of SOC as an important process in soil and carbon cycles for future regional carbon cycle assessment.

(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25) To achieve more efficient restoration results, it is necessary to continuously improve and optimize ecological protection and restoration measures through scientific and accurate evaluation of the effectiveness of current measures. Presently, in addition to scientific evaluation methods, establishing a natural ecological background system has become a key hotspot of scientific research to judge the effect of ecological protection and restoration.…”
