- Abstract:
-
Study of the spatial variations and scale effects of soil erosion and sediment delivery is critical for fully understanding watershed hydrological processes and sustainable watershed management. We reviewed published literatures and existed knowledge relating scale effects of soil erosion and sediment delivery, described the effects of spatial heterogeneity of environmental factors, including geology, climate, vegetation, and human activities on the scale effects of sediment yield, and summarized representative conclusions and the corresponding transformation functions for describing the scale effects of runoff generation and soil erosion on hillslopes. Finally, we proposed that future studies should pay more attention to the disturbance of scale effects caused by human activities and to the establishment of physically-based scaling functions. This review will provide information for further study of the soil erosion and sediment delivery processes, and support the planning of soil conservation measures and watershed management projects at different scales.
