In this study, 21 plots including 7 crop-rotation types (CRTs) under 3 different slight gradients (10°, 15°, 20°), were established in Dingxi, a typical semiarid hilly loess area in China. Eight consecutive years of erosion data under different gentle-slope cultivation conditions were compared and analyzed. The most interesting and key finding is that water erosion remained far higher on slopes with gradients of less than 20° than the tolerable criterion, even when some CRT measures and field treatments were implemented. It is highlighted that : Potato cultivation results in higher erosion rates than other crops on sloping land; Potato farming using additional measures should be conducted on terraces; Crop-shrub intercropping and farmland abandonment contribute to erosion control; Effects of CRTs on water erosion are also influenced by rain features
