摘要: A method to establish a Holocene sediment budget for 103 ha agricultural catchment representative the Belgian loess belt is presented. Soil erosion and deposition were determined based on 185 coring locations large excavation in valley bottom. Results integrated GIS interpolation techniques applied derive spatial patterns of sedimentation. Total soil erosion, export calculated results show that volumes are highly dependent technique used. Sediment delivery ratios between 20% 42% derived consistent with data reported previous studies. This clearly shows majority sediments produced during have been stored near their source area not delivered downstream rivers. The distribution within strongly slope gradient position catchment, which suggests that, since human impact began, topography has main factor determining long-term
