Slope Aspect Influences the Organic Carbon Content and Stock in Soil Aggregates of Cut Slopes in the Alpine Region of Southwest China
Road construction in alpine regions generates extensive bare cut slopes, which aggravates soil erosion and leads to substantial loss of soil organic carbon (SOC). Slope aspect modifies hydrothermal conditions, making it a critical regulator of SOC dynamics; however, it is unclear how it affects the physical protection of SOC within various soil aggregates in engineered cut slopes. In this study, we investigated the distribution and drivers of soi…
Soil Aggregate Stability and Characteristics of Nitrogen, Phosphorus, and Potassium Contents in Cut Slope Soils With Different Aspects in Plateau Areas
Slope aspects can affect the soil‐forming process. The implementation of road construction projects in plateau regions has resulted in the formation of numerous cut slopes. However, the soil aggregate stability and the characteristics of soil nitrogen (N), phosphorus (P), and potassium (K) nutrients under different cut slope aspects (east‐facing slope (EFS), west‐facing slope (WFS), south‐facing slope (SFS) and north‐facing slope (NFS)) are still…
Rare and Abundant phoD ‐Harboring Bacteria Mediate the Mineralization of Organic Phosphorus Fractions in Soil Aggregates During Cut Slope Restoration
Phosphorus (P) is the key nutritional element in the soil of cut road slopes undergoing ecological restoration, and the transformation of organic P (Po) is a crucial part of the P cycle. However, the role of phoD ‐harboring bacteria in driving the mineralization of Po fractions in road slope soil aggregates is unclear. This study analyzed road slope soils that had undergone 7, 11, and 14 years of restoration in the western Sichuan Plateau of Chin…
The distribution, effectiveness and environmental threshold of soil aggregate phosphorus fractions in the sub‐alpine region of Southwest China
This article is a study of total phosphorus (TP), available phosphorus (AP) and phosphorus (P) fractions of soil aggregates along an altitude gradient in the sub‐alpine region of Southwest China. We conclude that soil aggregate TP and AP contents are higher at 3980 m and 3347 m; there are no significant differences in soil aggregate TP at any altitude ( p > 0.05); the AP and phosphorus activation coefficient (PAC) are higher in 0.25–0.5 mm aggreg…
Time‐dependent effects of ecological rehabilitation on soil phosphorus fractions on cut slopes in the mountains of Southwest China
When a cut slope is excavated, the ecological environment in the footprint is destroyed. Soil spray seeding technique is used for the ecological rehabilitation of cut slopes in the mountain areas of Southwest China. However, there have been few studies of the temporal variation in soil phosphorus (P) fractions during the rehabilitation of the cut slopes. In this study, time‐dependent changes in soil inorganic P (Pi) and organic P (Po) fractions o…
The formation of small macro‐aggregates induces soil organic carbon stocks in the restoration process used on cut slopes in alpine regions of China
Road construction in mountainous areas of China has formed bare slopes on a large scale, which has aggravated soil erosion and carbon loss, and the restoration processes have changed soil structure and fertility. However, there are few reports regarding the differences of soil aggregate dynamics and SOC sequestration under different restoration process for cut slopes. In this study, three types of cut slopes [cut slope restored naturally (CSN); c…
Effects of frame beam on structural characteristics of artificial soil on railway cut‐slopes in southwestern China
Cut‐slope restoration technologies commonly used in southwest China mainly include using simple outside soil spray seeding (OSSS) techniques, or OSSS combined with an anchor frame beam. Artificial soil used in OSSS can establish a soil layer suitable for revegetation; the addition of an anchor frame beam not only fixes soil and shallow rock, it also acts to strengthen deep rock. However, there have been few studies on the effects of frame beams o…
