“…Different lower-case letters indicate significant differences among all treatments at p < 0.05 [Colour figure can be viewed at wileyonlinelibrary.com] had been not added in 4 years since the fish-scale pits were covered by gravel and straw in 2016 in this study. Compared to gravel, straw has a lower density and is easily eroded away by overland flow, especially under high-intensity and erosive rainfall (Wang et al, 2020). The decomposition of straw can also lead to a decrease in the amounts of straw materials.…”

“…An Infiltration hole is a supplemental measure of slope engineering. It is vertically drilled on the ground of the installed slope engineering measures and can be fillled with a certain volume to improve infiltration (Wang et al, 2020; Zheng et al, 2019). Runoff can rapidly and directly infiltrate into the deeper soil layer via the bottom and sidewall of the hole, rather than just through the ground surface.…”

“…Hence combining infiltration hole and slope engineering measure can intercept and infiltrate more overland flow into deeper soil layers and reduce water evaporation thereby increasing the utilization of runoff and alleviating the desiccation of deep soils. In addition, the nutrient‐rich sediments intercepted by slope engineering measure can be transported and stored into infiltration holes via runoff (Wang et al, 2020). This is essential to enhance the effective utilization of nutrient‐rich sediments and improve soil nitrogen and organic matter contents of the root zone for the growth of vegetation.…”

“…Slope engineering measures such as fish-scale pit, level ditch, and terrace can effectively intercept runoff and sediments via altering the microtopography (Chen et al, 2020;Feng et al, 2018;Garcia-Franco et al, 2014). The runoff and nutrient-rich sediments intercepted by engineering measures are the most valuable water and nutrient resources for slope revegetation and are retained in shallow soil layers (Feng et al, 2018(Feng et al, , 2019Wang et al, 2020). However, most of the rainfall in shallow soil layers is easily and rapidly dissipated into the atmosphere due to intensive soil evaporation in arid and semiarid areas and the utilization rate of rainfall resources is limited (Xu, 2011).…”

“…Runoff can rapidly and directly infiltrate into the deeper soil layer via the bottom and sidewall of the hole, rather than just through the ground surface. Moreover, the greater infiltration area offered by the infiltration hole enhances the ability of soil water infiltration (Wang et al, 2020). Hence combining infiltration hole and slope engineering measure can intercept and infiltrate more overland flow into deeper soil layers and reduce water evaporation thereby increasing the utilization of runoff and alleviating the desiccation of deep soils.…”

Soil water, nitrogen, and organic matter contents are among the main limiting factors for successful vegetation restoration on degraded slopes in arid and semi-arid areas.Combining slope engineering measures for revegetation is considered an effective eco-rehabilitation practice used to restore degraded slopes. However, a single slope measure is insufficient to efficiently utilize runoff and sediments to improve soil water, nitrogen, and organic matter for revegetation. In this study, four treatments were implemented on a hilly slope in a temperate continental semiarid area slope engineered with fish-scale pits (semicircle-shaped pit, 1.0 m in diameter, 0.5 m in radius, and 0.2 m deep), namely: with gravel mulching (GM), straw mulching (SM), infiltration hole (IH), and without other measures (CK). The effects of the combined measures on soil water, nitrogen, and organic matter contents were analyzed over 4 years. The results showed that the soil water storage (0-100 cm) showed no significant differences among all treatments; however, the soil (100-260 cm) of GM/SM/ IH treatment increased by 11.65%/8.62%/7.10% compared with CK (p < 0.05). The soil organic matter and nitrogen (0-100 cm) under IH were 73.34%/81.29%/98.32% and 77.37%/80.27%/85.31% higher than CK/SM/GM, respectively (p < 0.05). Overall, IH is the most effective measure for increasing nitrogen and organic matter, and it is equally effective with GM and SM to increase the water replenishment of deep soils in semiarid areas. Our findings provide the combined measures to combat soil water, nitrogen, and organic matter deficits for slope revegetation in arid and semiarid areas.

Investigating responses of soil greenhouse gas (GHG) emissions to vegetation restoration is important for global warming mitigation. On the Loess Plateau, a wide range of vegetation restoration strategies have been implemented to control land degradation. However, the thorough quantification of soil GHG emissions triggered by different modes of vegetation restoration is insufficient. There is still a knowledge gap regarding the regulation of soil biochemical and microbial processing on soil GHG emissions. To do so, we compared responses of soil GHG emissions to various types of vegetation restoration on the Loess Plateau, and investigated the changes in soil properties as well as microbial composition and activities. We found that artificial plantation of Caragana korshinskii had low soil carbon dioxide (CO2) emission, while natural grassland had high CO2 emission. The possible explanations could be related to higher moisture and microbial biomass carbon, and greater nitrogen limitation in natural grassland, which was controlled by actinomycetes and gram‐negative bacteria. Natural grassland had low soil nitrous oxide (N2O) emission and high methane (CH4) uptake, whereas Prunus mume had high N2O emission and Medicago sativa had low CH4 uptake, respectively. Soil N2O emission could be driven by fungi and gram‐positive bacteria which were affected by N availability and dissolved organic carbon. Soil CH4 consumption was associated with anaerobic bacteria and gram‐negative bacteria which were affected by N availability and moisture. These different emissions of CO2, N2O and CH4 generated the largest total GHG emissions for plantation of Prunus mume, but the smallest total GHG emissions for natural grassland and plantation of leguminous Caragana korshinskii. Overall, our findings suggested that the restoration of natural grassland and artificial N‐fixing shrubland like Caragana korshinskii should be encouraged to alleviate GHG emissions, with the practical implications for selecting suitable modes and species to improve ecological sustainability in degraded lands.

The introduction of exotic plants with high‐water consumption and high‐density planting have greatly changed the deep soil water environment on the Loess Plateau of China. Slope measures can intercept runoff to change slope soil water redistribution, however, the existing measures are not enough to improve deep soil water replenishment. Infiltration holes were used as a supplement of the existing slope measures. In this study, the effects of three different measures (the control without any measures, the level ditch, and the combination of level ditch and infiltration hole) on slope runoff and deep soil water redistribution were evaluated under field conditions. The results showed that the combined measure reduced the runoff by 44.1% and the sediments by 78.6% under an intense rainfall event compared with the control. After two rainy seasons, compared with the control and the level ditch, the combined measures significantly increased the soil water storage below 50 cm in the soil layer. Combining infiltration hole with level ditch improved the deep soil water replenishment within 30 cm from infiltration hole in a horizontal plane. Overall, the single‐level ditch was insufficient to improve deep soil water replenishment, and the combined measure can more effectively intercept runoff to increase the water replenishment of deep soils. Our findings provide a new thinking in regulating and utilizing slope runoff to effectively improve deep soil water replenishment in arid and semiarid areas.
