| 英文摘要 | Soil erosion removes soil particles, which mostly deposit in lower-lying landscapes. In the erosion-deposition catena, soil hydraulic parameters have been less understood, hindering our evaluation of soil water retention and release. In this study, profile soil samples were collected from the erosion topography (i.e., upslopes) and the deposition topography (i.e., check dams) of cropland and revegetated forest and grassland in a small catchment on China's Loess Plateau. Soil saturated hydraulic conductivity (Ks) and soil water retention curve (SWRC) were measured, and soil pore size distribution, water-holding capacities, and infiltration were investigated. The Ks, residue water content, and n (curve shape of SWRC) responded sensitively to erosion and deposition. With the increasing water suction, soil water content decreased more smoothly in the deposition zone, and the SWRC of the deposition zone was generally located above the SWRC of the erosion zone, which indicated that more moisture was mainly retained for sediments than for eroded soils at the same water suction. The higher ultramicropores (0.1-5 mu m) and cryptopores (< 0.1 mu m), field capacity, permanent wilting point, and available water content in the deposition zone also demonstrated its better water retention ability. However, Ks and infiltration rate at ponded water conditions monitored by HYDRUS-1d were almost one-half for the deposition zone than the erosion zone. Deep soils exhibited greater discrepancies in hydraulic parameters than surface soils between landscape positions, and revegetation could weaken the differences due to the attenuated erosion effect. These differences were mostly explained by the changed soil particle distribution and bulk density driven by erosion and deposition. In addition, the simple inclusion of the erosion/deposition topography could improve the estimation capacities of hydraulic parameters, especially for Ks and n. Our study shed light on the eco-functionality of water retention for deposited sediments but its inferior role in water release. |
