Control of Fissure Development on Soil Erosion in Karst Forestland Revealed by Simulated Rainfall Experiments
Monitoring soil erosion in karst regions poses significant challenges because of the complex geological structures, particularly in forestland characterised by frequent root activity where rainfall‐runoff processes remain poorly understood. In this study, the mechanisms underlying the control of underground fissure development on runoff generation and sediment transport in karst forests were investigated. Indoor simulated rainfall experiments wer…
Effects of rainfall intensity and underground pore density on the soil erosion mechanism of sloping maize farmland in a typical karst area of SW China
The rainfall intensity, slope, and underground pore density are major factors affecting the soil erosion of maize‐covered karst slopes. We studied the erosion process of maize‐covered karst slopes and the influencing mechanism of soil erosion on these slopes under different rainfall intensities, slopes, and underground pore density via simulated rainfall tests. The results are as follows: (1) No runoff was observed on the slope surface under ligh…
Effects of vegetation restoration types on soil erosion reduction of a shallow karst fissure soil system in the degraded karst areas of Southwestern China
Shallow karst fissures are the main hydrological paths, underground loss channels, and one of the most critical root habitats in fragile karst rocky desertification areas. Revegetation may alter the type of vegetation cover in fissures, resulting in changes to soil properties and erosion reduction. In this study, we evaluate the influence of revegetation on the soil erosion reduction of fissure‐soil–plant systems (FSPS) for three vegetation types…
Effects of preferential flow on soil nutrient transport in karst slopes after recultivation
In response to the global food shortage, a large amount of abandoned land in karst areas has been reclaimed as cultivated land, causing severe nonpoint source pollution. Preferential flow-driven soil nutrient transport on karst slopes remains poorly studied, though it is a major factor in nonpoint source pollution, as it responds to changes caused by reclamation. We explored the characteristics of soil preferential flow differences in recultivate…
The mechanisms of nutrient output through water flow from sloping farmland with slight rocky desertification in a karst region
Nutrient loss from sloping farmland with rocky desertification in karst regions leads to low farmland productivity and non-point source pollution. The mechanisms of nutrient outputs through water flow in such contexts under different rainfall intensities and slope angles were studied by using artificial rainfall simulation. Research showed that surface water flow occurred when the rainfall intensity was between 30 mm · h ^−1 and 50 mm · h ^−1 , a…
